Bug Description
*** IMPORTANT **
*** The fix is not included in TRUSTY. Will be included with next SRU. ***
If you can reproduce this bug please be sure to provide the following info:
1. Do you use a multi-head setup? If yes, using just one monitor fixes the issue?
2. Can you reproduce all the time?
3. Do you use ldap? If yes, using gnome-screensaver fix the issue (see comment #115) can you still reproduce that?
4. Please consider posting /var/log/auth.log (at least part of it, should not contain sensitive information)
5. Please specify the unity version
*** END IMPORTANT **
[Impact]
Sometimes (but not always) after locking the screen there is the situation not having any input field where I can type the password to unlock the session again. The shaded gray area simply does not have the input field. I can't do anything, I have to switch to text console and stop/start lightdm service to cure the problem loosing all of my session :(
[Test case]
1. Lock/unlock the screen multiple times
2. Expect the lockscreen password input field stay there
[Regression Potential]
Lockscreen shield isn't properly shown. Or fails to login.

I don't think so, at least not recently but this install is quite old and was upgraged during the time to newer and newer releases. However what made me thinking is the fact that it does not always happens only sometimes. Also, it's the situation only since some days it didn't happened before, so some kind of upgrade since then can cause it (and I am sure there was no "pam game" since then at least).

Just noticed: sometimes (if the problem occurs) I see the screen I've posted after locking the screen (ctrl-alt-l). If I don't touch the keyboard and mouse the screen fades into black and after some seconds I see the login screen presented with full bright again where I can unlock the session. I don't know too well the new features of the unity desktop, but I guess the first (problematic) screen may be the unity-locker and only that have the problem. Moreover, it's kinda strange for me that I lock my computer (notebook) so I expect that it should save power to turn off display, fade to black etc, but after it happens I get the login screen where I can unlock my session but it's not faded etc. I try to adjust settings in gnome control center and unity control center (I am not sure they are some or not) but I couldn't figure out what settings affect these exactly.

@LGB [Gábor Lénárt] that you don't see input field doesn't mean that you can't type password and unlock the screen.
I was trying to reproduce a bug that some people described about fullscreen YouTube videos showing on top of Unity lock screen. I managed to get once a screen locked which would flash and without text input field visible just like on your screenshot but I just typed my password and unlock normally.

Also affected randomly. For me its impossible to unlock again. Even if I type my password blindly.

Joan CiberSheep (cibersheep) wrote : | #10 |
I just noticed two things:
- If focus is on a text file when Unity locks, when you type the password is been typed in the text file (even if it's not visible until you manage to unlock clicking on top menu and clicking again in the password area)
- Sometimes, visualizing a fullscreen video, system lock but it keeps showing one of the frames of the video making dificult to unlock. The way I found to unlock is to press ctrl+alt+L to lock and type the password

I'm having this issue as well. It's not very frequent but it has happens once in a while.
I have a machine with an NVIDIA card, using proprietary nvidia drivers, dual monitor display. Since it's not very often, I haven't yet been able to correlate it with any specific event.
My pam configuration is customized, but I don't believe it's related at all, since most of the time it works fine.

I'm also affected. It was not acceptable for me to loose my work, so I was looking for workaround. And I have found it:
What I did:
0) Switch to VT1 using Ctrl + Alt + F1, logged in
1) killall light-locker
2) killall gnome-screensaver
3) killall /usr/lib/
4) /usr/lib/
5) unity --replace
I think number five (number 0 prepended) solves the problem, but in order to be sure, I have added another tries.

Evan is right.
If you find top panel missing icons and/or menu-in-
compiz --replace
I have found somewhere this command prepended by 'setsid ', but don't know if it changes anything.

Here as well, fresh install of 14.04 on a Dell Latitude notebook (Intel graphics) with the internal screen and two external screens being in use.
Happens randomly as it seems.
Only one time I didn't get password field but at least the cogwheel icon on the top right, so I could select "switch user".
But most of the time there are no user interaction elements whatsover.

I've had this happen twice. Each time was slightly different.
I have dual monitors and the first time it happened, I moved my mouse to the other screen. When the user login box switched to the screen my cursor was on, the password field appeared. When I moved my mouse back to the second monitor, this time, the password field was there.
The second time it happened, both screens were the same with no password field. Moving the cursor back and forth never reloaded the password field and I had to take other measures to log in.

Another observation: in case of problem also shutdown does not work sometimes, it simply doesn't do anything, even if try multiple times. The only solution then: switch to text console, log in, give command "init 0" as root.

I've also encountered this issue with a dual monitor setup.
I only seem to trigger it when locking my Dell Latitude E6530 (NVIDIA Corporation GF108GLM [NVS 5200M]) with Ubuntu 14.04.1. Sadly I cannot reproduce it reliably, but I trigger it in maybe 5% of the cases.

I have the same issue here, Ubuntu 14.04.1 64bit (3.13.0-33-generic) with Unity, using Dual screen and NVS 300, Nvidia proprietory drivers v 340.24.
Sometimes in the past I was able to get the input password box to appear when I was moving the mouse around from one screen to another. This was causing the login box to change screens and sometimes the input would come back. Lately this doesn't work for me any more, and the only work around is the unity --replace command from a terminal. I also noticed that when I come back to my session my gnome-terminal is completely lost in the background and if it was minimized I cannot bring it back. I don't know if this is related.

I am also having this issue. I attempted the "unity --replace" workaround, and it appeared to kill my existing session.
I'd also like to note that I use VMWare workstation (my machine with the problem is the host) and if I leave my cursor in my vmware window the screensaver doesn't activate until I move my mouse out of VMware. This may be unreleated but I wanted to mention it in case it is meaningful to others.

It also affects me. Dual monitors, 64 bit, Graphics: Intel® Ivybridge Desktop - also only every now and then, not always.
When I can't login and try with 'unity --replace' in console (pressing Ctrl + Alt + F1) I can login again but top menu is missing in all applications, but 'compiz --replace' doesn't work (it prints some lines one of them being: Fatal error: Coulnd't open display).
But if I do Ctrl + Alt + F1 and run 'unity --replace', then go back to unity with Ctrl + Alt + F7, then I can login - and after I am logged in in unity and open a Terminal there and run 'compiz --replace' then also top menu comes back.

This is happening much more often since the latest Unity releases. There were several changes done to the lockscreen and it seems that these changes made this problem more frequent.
It seems to be particularly frequent when the machine is under heavy load (i.e. compiling stuff), which seems to point to some kind of race condition that is made worse when things are going slow.

There is many people with such defect affected - we can add debug for some component to triangulate this bug?

I am affected as well. Dual monitors, Intel graphics, Chrome was open. Happens randomly. Sometime the password box is still visible on one screen, but not on the other. When it disappears on both screens, only the unity --replace and compiz --replace methods mentioned above will allow me to get back to my desktop.

Let me add a small twist to this...
I have a triple-screen setup on an ATI card. I have the same issue above, but I also have another...
Sometimes when I come to my computer in the morning for work, one screen will not have the input field, but two others will. If I mis-type my password in one of the working screens, the input field then disappears. If I type it incorrectly in the other window, the input field disappears on that one as well. Then I'm back to the issue in this bug. But if I do type it correctly on either of the working monitors, then sometimes I'll get another lock screen, and sometimes I'll get my desktop.
Additionally, if I do end up in a spot where I have visible fields, if I restart lightdm and then login, then I get the lock screen again after logging in and have to enter my password again.
The Unity Lockscreen has been a huge nightmare for me...

Same here, same hardware as henryweismann in comment #19 (System76 Gazelle pro), with external monitor (i.e. dual monitor setup).
Switching to VT1 and running unity fixes it but then the windows are on different desktops, some settings are reset (e.g. ctrl-alt-0 does not minimize windows anymore, top menu line is empty, no indicators etc.).
Also tried compiz --replace and unity --replace, neither fixes the keyboard shortcuts and empty menu/panel at the top of the screen (where notifications are).

Happens for me on Lenovo T420 frequently. At work, I hook it up to the second monitor.
Yesterday I rebooted, it came up in dual monitor mode, and it was fine all day, including closing the lid, and the password box is there. At the EOD, I close the lid, unplug the monitor. Came back in, plug it back in, initial log in is ok. And then when the screen times out, both screens doesn't have the password dialog.
End up doing a unity --replace on VT1

I tryed to reproduce this bug on a single-screen computer but I didn't see any problem, so I think this bug is related to the dual-screen configuration. To ensure : Someone has this bug on a single-screen computer ?
I know somebody who uses Ubuntu 14.04/Unity on a dual-screen computer and seems do not have this bug, do you need specific informations about the configuration of his system ?

Hi Giampiero,
Unfortunately the fix for Trusty will need some weeks in order to be available, because we're still in the verification phase of the previous Unity SRU that needs to go in, before we prepare a new one (you can help to speed up things by verifying the relevant bugs¹, BTW)

I have a workaround for this, use Gnome instead of Unity.
It took me a while to realize/figure out that it's pretty painless to just run a different window manager on Ubuntu. I did look at maybe switching to a different lock screen but there was no straightforward way to do that.
It turns out you just use apt to install gnome-shell and then from the login screen you have the option to run Gnome instead of Unity (click the little icon on that line with your name when you're logging in to select the window manager you want).
The bug makes Unity so inconvenient to use that I was considering switching to another Linux distribution. I don't see any downside to switching to Gnome so far, so this seems like a reasonable workaround until the problem is resolved. Or maybe forever, I don't care about Gnome vs. Unity and Gnome seems to work just fine.

I would like to know the answer to that as well. Back in the good 'ol
days the screen lock was a separate process, and "pkill -9
gnome-screensaver" would bring back the desktop. But now...? There is
a process called "/usr/lib/
but if I "kill -9" on it, it just comes back with a new PID.

Usually only happens when both monitors are active, and when a VirtualBox VM is on the screen. Today, I was on a workspace that didn't include any VMs. First occurrence after locking I got a blank login on one monitor but the second allowed me to enter password; a few minutes later a second lock screen resulted in both monitors refusing to accept a password.

NOTE: I wondered if this patch was applied since my last login / Unity load. Checking update history shows it was installed on 11/14/2014 along with kernel patches, meaning a reboot was required post-install.

I still get this issue on Ubuntu 14.04. Managed to get an input field after killing all instances of unity-panel-service (it might be that you'll have to run killall several times). After doing that I get windows messed up among desktops. The good thing there are borders and titles for all the windows. Usage of "unity --replace" solution works, but removes borders and title bars for all windows.

I don't know if it helps, but I always had problems like "no input field for password" or the "double unlock" (if the first problem does not occur, unlock presented another unlock field with a sightly different screen) problem on my notebook. Then I noticed, I have a package installed named "light-locker" (I am not sure about the name though, just by heart now). After removing that package I had no problem like these since then! Since I've installed meta-packages xubuntu-desktop and lubuntu-desktop as well (so I can test different desktops) it can be a reason as (if I am correct) these packages depends on light-locker. Removing them caused those meta packages to be removed as well (again, if I remember well enough), but at least since then I have no problem with regular ubuntu (unity) desktop locking&unlocking.

FWIW - I have Marco's PPA package installed and I continue to see this issue. Another issue that seems partly relevant is that my screensaver never stays on for more than a few minutes before I see the lock screen again. I notice that when this happens, this issue is more prevelant. Here is a snippet of my auth.log (note that I, nor anyone else is at the office during this time frame) and 6:25 is when I first sat down at my desk to log in.

We also have this problem on several machines, and I hope I can contribute to getting it fixed.
Removing light-locker fixed the "double unlock" problem, but not this problem. The machine is a fully up-to-date Ubuntu 14.04 with LDAP authentication.
The output of ls -l /sbin/unix_chkpwd is
-rwxr-sr-x 1 root shadow 35536 Jan 31 2014 /sbin/unix_chkpwd
I cannot post full auth.log because of personal data,
but I will try to remember to grap the last lines of the log the next time the problem appears.
The problem occurs only randomly and not very often (maybe once per week). It happens less often now that the "double unlock" problem is fixed, I guess simply because I have to enter my password less often now.
A reliable work around is to switch to a text console, login as the same user, and run "unity --replace".
This restores the password input field. After unlocking, the panels are missing but I can fix this by opening a terminal window and running "unity --replace" there.

Sorry for my english but I don't understand if the fix works or not when you say "We released a fix but it does not work" then "The one we released was text entry not showing randomly on multimonitor and seems to be fixed", for me it's contradictory.
What I can say :
- My PC using Marco Trevisan's unity package (https:/
- Another PC using Ubuntu's unity package, randomly, I have no input field to type password for unlock (normally this PC is up to date but I have to check).
Both use multimonitor and LDAP authentication.

I cannot imagine how a missing password input field in the lock screen could be related to an LDAP configuration issue on our side.
If the authentication would fail after entering the password, then yes, of course this could be such a problem.
But a password field should always be shown by the unlock screen, regardless of the authentication backend.
Also our LDAP configuration is working for several years now without problems.
Only since the upgrade to Ubuntu 14.04 this problem with the lock screen has started appearing.
All other applications, including the login screen (lightdm) are working fine.
By the way, we have a dual monitor setup, too.
Our home file systems are on an NFS fileserver, mounted using automount and with root_squash enabled (this means that root does not have full access to my home directory, but only the same rights as all other accounts). If there is a root process trying to access files in my home this would fail.

Because we don't show a text entry if PAM (the authentication module) does
not respond correctly. We wait for PAM to ask the passoword not the
opposite, and if PAM fails there is nothing we can do about. Briefly PAM
works like that: we ask to authenticate the current user, pam responds
asking us to show a text entry with some text (like "Password:", etc...),
we send the password to pam, etc. If for some reasons pam cannot
authenticate the current user, it answers with an error.
Gnome Screensaver was working out of the box?

No.
For example, if smart card authentication is in use, the PIN entry field should not be shown until and unless the smart card is inserted in the reader.
If challenge-response authentication is in use, it would incorrect to display the response field until the user ID has been entered and a challenge presented.
There are a number of scenarios in which it is just wrong to present a password field. It is correct for the Unity lock screen to not always displaying a password entry field when it has not been instructed to do so by the underlying auth mech. Any authentication dialog that does so, and actually authenticates the user as a result, possibly has a critical security vulnerability.
It would be a good idea to audit your local authentication setup if you are seeing this bug.

For auditing my PAM config, could you please tell me which PAM config the lock screen uses
(i.e., which file in /etc/pam.d is used)?
So far I could not find any differences between them.
The LDAP config is in common-
All these services (login, lightdm, polkit-1, sudo, sshd) are working fine.

For my part, reading explanations above, I understand it may be an LDAP configuration issue.
However, I perform tests on 2 PC with the same configuration (LDAP Authentication, home areas served by NFS + automount, multimonitor) :
- PC 1 using Marco Trevisan's unity package (https:/
- PC 2 using Unity up to date from Ubuntu repository, I get this issue randomly (about once a week).
So I think this is an issue related to Unity.
Like there is a known and not solved Unity bug about this issue, for me, this is not logical to search the cause of this bug elsewhere (maybe I'm wrong).
So msp3k and Philipp Wendler (and others using LDAP authentication), could you test Marco Trevisan's unity package and tell us if it solves this bug ? https:/

They run as root that's why. Try to lock using gnome-screensaver (without running it as root!) and let me know if you can unlock the screen.

I've been suffering this bug for months now. Today I noticed some issues with window animations before it happened, and it came to my mind that it might be compiz-related. I killed compiz and the login screen was gone, without losing the unity session. It's the first time that I manage to go back to my session without losing the data.
This is a Sony Vaio running Ubuntu 14.04.1 with dual monitor.
After that, when the screen lock appeared again, the password field was there.
This seems to me a better workaround than unity --replace, if it proves to work consistently. Worth trying it.

Okay, I set System Settings > Universal Access > Typing > On Screen

Then I hit alt+control+L to lock.
Sure enough, I got what looks like gnome-screensaver.
Via an SSH login I confirmed that gnome-screensaver was indeed running,
and running as me and not as root.
Entering my password returned me to the desktop with no problem.
I repeated the lock test four times.
I'll ask my boss to make the same settings change and let me know if/how
that changes things for him, and pass the results on to you guys.

1) The bug just bit my boss again. Here's the auth.log:
Dec 10 09:13:23 anolis compiz: PAM unable to dlopen(
/lib/security/
file or directory
Dec 10 09:13:23 anolis compiz: PAM adding faulty module: pam_kwallet.so

opened for user root by (uid=0)
There's nothing out of the ordinary here compared to my other hosts.
There's a mysterious complaint about pam_kwallet.so, but all of my hosts
complain about that.
2) There is something new to note:
When the bug bites, not only is there no password field, but the
indicator apps also disappear from the top-right of the screen. I
noticed this when I tried to switch to another user in hopes of being
able to log back in. Attached is a screenshot I grabbed via vinagre.
3) I set System Settings > Universal Access > Typing > On Screen
Keyboard = On
We'll see if the problem persists when using gnome-screensaver.

1. Yes. Dual monitors.
2. No. The problem is random.
3. Yes. We have just switched to gnome-screensaver for testing
purposes. Initial tests look promising.
4. Included auth.log entries in a previous message
5. unity 7.2.3+14.

Seems like there is a misunderstanding: the fix is not included in Trusty (14.04 LTS) but just in 14.10+. Will be inclued in next SRU.

I had a new development.. Maybe I should report as a new bug? In case this helps anyone as a workaround or to fix the bug I thought I would post here:
I had the lock screen complain of the wrong password. I sure it was the right one as I tried many times and eventually opened a virtual terminal where the password worked (tried several times again in the lockscreen to be sure) BUT instead of using the unity or compiz trick as usual I found this process with ps -ef:
/usr/lib/
and killed it, then the lock screen would take the password. This might be something for you to try I guess as as a workaround next time.. At least when I restarted the old way, the desktop, that is the panel, didn't quite work afterwards (at least the time disappears from the panel), and I would restart after getting in to be on the safe side. I might do that now also, but at least I do not seem to have any problems.
[This may not stricly be the same bug, but I guess the bug is in the same program and I would guess both this and the bug in the subject have the same root cause - memory at some point running out and making trouble afterwards.]

Yes, BUT I think you are getting at that with my layout the password would change if I press the same keys in another layout. It doesn't (matter if the English one is used). It's a guess.
You think this could be adifferent manifestation if the same bug? Should *I* file a new one?

I use Icelandic. It has extra letters, such as þæðöÞÆÐÖ (and accented), over English (as it is a superset I never change to English layout) but as I said I'm not using those in my password. And this bug had just happened for the first time while getting no password prompt has happened many times. I changed to gnome-shell, at least to try out, so I do not expect the bug to happen there..

I've just run into this with Ubuntu 14.04.1, updated today at about 15:45. I didn't happen immediately after the update, in fact it was fine for a few hours so I think it's unlikely to be related.
Some info:
* unity --version: unity 7.2.3
* uname -r -v -p -i -o: 3.13.0-43-generic #72-Ubuntu SMP Mon Dec 8 19:35:06 UTC 2014 x86_64 x86_64 GNU/Linux
* Dual-head?: yes, 2 monitors
* modified pam?: no, and not using ldap
* Running 2 VMware Workstation 10 VMs (both Windows 7 x86_64)
I have too much work (in VMs) going to risk re-setting unity, so I'm going to have to wait for it to timeout and hope!

Resetting unity from tt1 should be just fine. Or you can run metacity

Same problem here:
- No LDAP
- Dual-monitor setup (Intel HD graphics in i7-4770)
- Usually two users are logged in graphically (VC 7 and 8)
- Usually it starts happening for the second user (VC 8):
- The box on the locked screen shows the user's name,
- The box does not show the password entry field,
- There are no icons shown in the top bar (i.e. no way to shutdown).
- As long as the problem doesn't happen on the other VC, the session on the
problematic VC can be recovered by:
- Switching to the still working VC (which is in locked screen mode),
- Clicking on the icon in the upper right corner, and selection "Switch
work, and merely switches to the problematic VC.
- A new lightdm session appears. Log in with the account of the user
whose session has problems.
- The system switches to the problematic VC, and unlocks it.
- Logging in on text VC1 and running "unity --replace" unlocks the
problematic VC, but kills compiz.
- Running "compiz --replace" in the graphical session restarts compiz, and
locks the screen again, now showing a password entry box.
- After unlocking the screen, everything works again, but all open windows
have been been moved to the first desktop, so I have to untangle the desktop
clutter manually.

I spoke too soon.
During untangling my desktop after pressing Super-S, I noticed:
- Some fullscreen evince windows don't want to be moved to another desktop,
they always pop back to desktop 0. It seems they have lost their close/minimize/
maximize icons, too.
- Moving windows after Super-S is slower than usual, and sometimes complety
blocks, so I have to press Super-S twice to continue.
So I gave up and logged out, and can online recommend "unity --replace" and
"compiz --replace" to recover critical applications that had been left open.

I have the same problem. It happens randomly.
My environment when the problem appears:
* 2 screens, the problem normally affects both monitors, but sometimes the input box for the password appears on one of the monitors... it is random.
* 1 session (I only have one user)
* normally I have a rdesktop session opened when the problem happends.
$ unity --version
unity 7.2.3
$ dpkg -l unity

ii unity 7.2.3+14.
I'm going to update to "Landing PPA 004". I'll comment in the next days if the problems is fixed or not.

I updated to Unity 7.2.4 (using the ppa described above) and still have the problem. It happens quite regularly, but not predictably.
Ubuntu version:
LSB Version: core-2.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.1 LTS
Release: 14.04
Codename: trusty
Dual monitors. The password box only appears on the monitor that is "active" as defined by where the mouse pointer is. When it stops working the dialog box has no text-entry field. I can switch the dialog from one monitor to the other but the text-entry field for the password will never appear.
I can SSH into the machine, issue "unity --replace" and it will cause the password prompt to reappear. I can then issue "unity --reset-icons" (but only after entering my password and finding an open terminal windows - this doesn't work from the SSH session) to get the UI to the desktop working again. If there is no open terminal window I am out of luck - there is no keyboard interaction with the desktop and there are no controls available to open a window with a mouse). I have to fix all my terminal windows which have moved to the upper left of the leftmost screen but I'm OK.
The "unity --reset-icons" command hangs and if I ctrl-c the terminal session or stop that process I lose the UI again. But as long as that terminal session stays open things work. It enter the error state again (no password field in login dialog) after I've done this.

Update on Comment #143. I have yet to see the problem again. When it last happened I had installed the ppa but not rebooted the system. While Unity indicated that 7.2.4 was running it' s possible that the ppa didn't restart a necessary process. It's now been over three days with many opportunities for problems and I have not seen a recurrence since I rebooted (after I posted #143).
I'm knocking on wood as I write this. I'll post again if I see a recurrence after installing the ppa and rebooting.

I have the same bug as described on my fresh install of Ubuntu 14.04, however I'm with a newer kernel because of problems with my wifi drivers in previous versions, which were fixed:
Linux
3.17.3-
#201411141335 SMP Fri Nov 14 18:36:40 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux
Ubuntu 14.04.1 LTS
14.04
trusty
The problem is reproducible multiple times. After closing the laptop lid and going in suspend for a longer period, when opened the laptop displays the welcome screen with my wallpaper, but does not have any field to enter password. Clicking any sound/lang icons on the menu bar does not help, but waiting for a bit of time does.
Diagnostics so far:
So I dig a bit myself and looked at the log of lightdm, with "the problem" occurring here:
[+0.28s] DEBUG: Session pid=1224: Running command /usr/lib/
[+0.28s] DEBUG: Creating shared data directory /var/lib/
[+0.28s] DEBUG: Session pid=1224: Logging to /var/log/
[+0.33s] DEBUG: Activating VT 7
[+0.33s] DEBUG: Activating login1 session c1
[+0.45s] DEBUG: Session pid=1224: Greeter connected version=1.10.3
[+0.60s] DEBUG: Session pid=1224: Greeter start authentication for alex
[+0.60s] DEBUG: Session pid=1283: Started with service 'lightdm', username 'alex'
[+1.67s] DEBUG: Session pid=1283: Got 1 message(s) from PAM
[+1.67s] DEBUG: Session pid=1224: Prompt greeter with 1 message(s)
[+3.49s] DEBUG: Session pid=1283: Authentication complete with return value 0: Success
As can be seen the period 0.60-1.67 is just waiting for the PAM service to respond (1 minute wait). I typed my password asap as it was available, so my guess is it is connected with the PAM service. I will look into it, but if someone has an idea why would be great. The /var/log/auth.log does not contain any useful information for the why the problem is occurring.

Also if you could answer the question in #108 this could help us a lot to further debug if necessary the PAM module.
And to add, I'm also using a finger print reader (fprintd) as an authentication before the password, but there are some interesting facts about it(before anyone jump and point fingers there):
It has a timeout of 10s, the wait for the password text area is ~1 min
If I suspend the laptop manually and wake it it uses the fingerprint reader normally.
If I close the lid and open it - the finger print reader authentication is not available and the bug occurs.
Conclusion:
Possibly the fprintd.so library is not loaded for some reason on lid open, or the PAM module encounters some problems, after which it falls back (somehow) to the unix password. Again if you answer #108 would be most appreciated.

I see this on systems with LDAP, and systems without. It's just happened on this machine, which is built from scratch about 1 week ago. It's with a new user - so all the user config is as created by a new clean Ubuntu system. I haven't customised PAM at all.
I see lots of failures in auth.log, but none of them are specific to this condition. E.g:

I updated my machine recently to the current Unity 7.2.4 and this solved this issue for some time.
BUT: Now I am experiencing it again, exactly 50 % ( that is actually 25 % of time, see below) of times I log into my maschine. My case if different, though. When my Laptop wakes up from sleep I always have to log in two times each time. Meaning I enter my passphrase, the screen unlocks, I see my screen 1-2 seconds, the screen starts flickering and then it locks again, this time without the input field. I then close my lid so that the machine hibernates again. I wake it up again, and have again to unlock the machine two times. This time I have in both cases an input field.
So, you could say I have to log in four times every time I want to use my machine. This is always reproducable, btw.
I did not reboot the machine so far, meaning it is up for some days now, where in the beginning it had it prefectly working with just one needed attempt to unlock the machine.
I attach the Auth.log entry from the last login, which seems a bit weird...

Can you give more detail how to do this? Man pages have no mention of "debug" at all.
My entire pam.d/unity looks like this:
-----<start>-----
@include common-auth
auth optional pam_gnome_

Where does the debug keyword go?

So you just add it to the end of the line of an entry, of course monitor the /var/log/auth.log, as this means you are passing it as an argument, which might not be valid for all packages(its a common practice to be tough, but who knows). For instance my /etc/pam.
#
# /etc/pam.
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the
# traditional Unix authentication mechanisms.
#
# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
# To take advantage of this, it is recommended that you configure any
# local modules either before or after the default block, and use
# pam-auth-update to manage selection of other modules. See
# pam-auth-update(8) for details.
# here are the per-package modules (the "Primary" block)
auth [success=2 default=ignore] pam_fprintd.so max_tries=1 timeout=10 debug
auth [success=1 default=ignore] pam_unix.so nullok_secure try_first_pass debug
# here's the fallback if no module succeeds
auth requisite pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
auth required pam_permit.so
# and here are more per-package modules (the "Additional" block)
auth optional pam_cap.so
# end of pam-auth-update config
If you want full debug some packages (including fprintd) would require to be compiled from source with a debug flag on. Even without that, enabling debug can produce some usefull stuff in the auth.log

I was experiencing similar problems to post #32 above using VMware Player 6, latest version.
Dual monitors. I don't recall seeing the problem with only one, i.e. the built-in laptop one.
Problem did not occur every time - only after some varying amount of run time.
AFAIK I don't use ldap, but I will look later.
I will post auth.log later.

My workaround was to send a hangup signal to compiz from VT1. I say was because as of three kernel updates ago, the problem has become worse. Now when the screen timeout occurs when my mouse is on the Win7 VMware VM, when I move the mouse to the host screen (which is the built-in one), the login session crashes and restarts as if I sent ctrl-alt.backspace, thus wiping out all running apps. Needless to say, this is an unworkable situation.
I am happy to provide any helpful information I can to help target this problem. Let me know if my situation belongs in different/another bug report.
FYI, I much prefer the old bug. I might try reverting kernel releases using grub and see if that helps.

I tried reverting back to 3.13.0-45, but the session still crashes when the screen times out while the mouse is positioned over the VM. Next I will try reverting Unity versions, if that is possible. Kernel is back to 3.13.0-51.
One other item - if the screen times out with the mouse in the host, i.e. on the built-in screen, the session will act as expected and present the login screen.

I'm on Ubuntu 14.04.4 LTS Trusty. This report applies to a few weeks back (was at least 14.04.3).
If I recall, I did get the input field (but months earlier I got no input field onces in a while).
Sorry, I forgot to report, but then could reproduce easily, since memory was low. If I locked the screen, then I couldn't get back in, but realized if I got into a virtual terminal and killed one of the chrome processes, to make some room, I could get in.
Since then I've given up on the Chrome browser and went back to Firefox. I'm not saying this has happened always with Chrome or it is the cause (or Firefox the solution), just that it is an example of a program that can fill the memory so it can be done manually reliably in other ways to reproduce my bug.
Sorry if this is not the same bug, do say if you want it reported separately. I find it very likely that memory low could be the same problem, even when the symptom is slightly different.
1. Do you use a multi-head setup?
I think not.. I do have another monitor, have set up dual in the past, now the other is unconnected, and the mouse pointer does not go "off" to either side.
If yes, using just one monitor fixes the issue?
Not sure, I must work with 2 screens
2. Can you reproduce all the time?
Frequently every day, under conditions above.
3. Do you use ldap? If yes, using gnome-screensaver fix the issue (see comment #115) can you still reproduce that?
I'm not sure if I'm using ldap, I guess Thunderbird may be, we do have ldap at work, not sure I'm using it for a "address book".
[Seems strange that ldap would be the cause.., what could I likely be using else, that uses ldap?]
Not sure what #115 is telling me to do or if asking for this info:
ps -ef | grep -i screensaver
qwerty 32042 30834 0 17:09 pts/27 00:00:00 grep --color=auto -i screensaver
4. Please consider posting /var/log/auth.log (at least part of it, should not contain sensitive information)
Probably outdated..

I'm still having this problem even after all the latest updates. The status says "fixed released" but I'm still facing this issue. I'm using Ubuntu MATE 16.04. This doesn't happen every time, but sometimes when resuming from suspend, I cannot type my password. The work-around that works for me is to "switch user" and then log in as myself. This will allow me to resume my session, but my mouse cursor is invisible for a while, but comes back eventually. I think the "fix released" status should be removed as this is clearly not fixed.

I have had this bug since I installed 16.04 (Not an upgrade)
It does not happen often but when it happens it is always when returning to my normal user id after having switched to another user id.
So basically I click upper right corner and selects another user, say user2, when I am logged in as user1.
When I am finished with user2 I just log out and am normally returned to the login window where I can login as user1 again and the session is resumed.
When the bug strikes it is not possible to login and only a switch to TTYx and executing a
$ sudo service lightdm restart
will give me back a working login page but I have to login twice before I get access and then is of course all work in the old session gone.

running 16.04.1
Fujitsu Lifebook E752
single head.
no screensaver that i know of.
i don't use locking, but when returning from sleep the screen is locked.
so far, most of the times the pw-field is there, but not usable.
i also think that there should be icons in the top right corner and a clock maybe? the space is empty.
just now i had a case of pw-field missing altogether. found this bug. did not find any newer bug, so i post here.
initially recovered with workaround "unity --replace" which made the PW-field show up. i could unlock the desktop, seemed fine.
now desktop totally screwed up: alt-tab unresponsive, launcher missing, top-bar missing, whole thing looks funny. mouse works, can use scroll-wheel and mark text in a left-over, fullscreen terminal, but not type..
put computer back to sleep, woke up again, now got a gray box that says "Chris" (my username) "Password", a field and button s switch user and unlock. never saw that before. might be because i tried to use described locking procedure (ctrl-alt-l) which was suggesting to fix some things, which did not seem to work.
typed PW, screen went away. back to screwed up desktop.
keyboard seemed useless. noticed that ctrl-n opens file-browser. works repeatedly. with those windows open, i can use alt-tab to switch between these new windows. browser, netbeans, thunderbird (should all be still living in the background) are not presented.
task-switcher looks funny, too. just a row of images and a box around the middle one.
used file-browser to start a video. worked. can now use alt-tab to switch between file-browser and videoplayer.
i am a noob. if you need something, tell me.

This really isn't acceptable for our use. We may have a rather smallish
organization (I manage 103 Ubuntu machines, most of them user-facing
workstations) but we are a national research institute and we give Linux
and Ubuntu international attention every time we have a group of
scientists arrive for a workshop simply by running something other than
the standard Winblows ecosystem. Creating a second account for them
really isn't feasible, and trying to convince them to log in a second
time, "just in case," just doesn't work. For many of them this will be
their first exposure to a Linux desktop environment, and if they get
bitten by a bug like this then it'll probably be their last. This bug
makes both Ubuntu and Linux in general look bad, and that makes me sad.
There are some functions that you just expect to work without fail, and
this is one of them.

The lack of indicators might indicate a problem on the upstart user session. This upstart failure can confuse PAM as well. I'm going to propose a branch that will allow the system to lock if there are such types of failures.

Not sure if this is important, but I can notice the following: if I switch to the second (or any other than me) logged user (Ctrl + Alt + F8), it works normally. I can, then, in second Xorg session, select my user from indicators and then log in.
And, I'm not sure if this is related, but appears that all the times this happens, Unity dash launcher don't display icons for any application (see attached screenshot).

The only workaround I got is that I made a dummy user that I always login on terminal 7. When any in the family gets this problem they hit CTRL+ALT+F7 to that user lockscreen and use its fast user switch to pick their own name. Then you get login prompt and can access your session. Once in the session you get the same problem if you lock the screen so its just to be able to save your work, close appications and kill the screem with AltGr+SysRq+k since the logout will show a logout button that will not work.
Once logged in again though the lock screen is normal for a random duration of unlocks before the same happens again.
It beats loosing data but a fix would be nice.

And the "fix" doesn't work as I'm using Unity 7.4 on Xenial LTS patched up with the newest fixes.

@azzar1: I faced today again this issue, after install the modified Unity from the PPA. I resumed after suspend. Yesterday all the family logged in.

This is getting wores.. The workaround mentioned above "@Klemen, as a work around I make sure that a second user is logged in (most of the time one of my children). If I am locked out, I can switch to a different X-session (ctrl-alt-f8 or so) and then switch to my user with the menu in the top left corner. Then I can enter my password." is not working anymore. When I switch X-session the screen in that session just keeps flickering and blinking and there is no way I can switch to my user with the menu...
Will this be fixed or should we abandon Ubuntu as a GUI option for Linux? Should I switch to KDE? Any other recommendations?

Just for the record: I had Ubuntu 17.10 (upgraded from 17.04 which was upgraded from 16.10) running on my HP Spectre x360 just fine with GDM3 and Unity and when the screensaver kicked in or I locked the screen, it turned to the GDM3 greeter.
A few days ago, I cleared my SSD and installed 17.10 from scratch. But now, when I lock the screen, I see what looks like the LightDM greeter with a red "Authentication failed" message and "Switch to greeter..." where the password input should be. I then have to Ctrl+Alt+F1 to the GDM3 greeter and unlock from there. Why is that?

Using the "Switch to greeter..." button you should be able to login without any Ctrl+Alt+F1 press, isn't it?
Andrea might help more here, though.

A few reboots later, I'm now able to unlock the notebook from the LightDM lockscreen. There's no "switch to greeter" anymore, but a real password entry field which works. However, I still don't know why I had the GDM3 lockscreen before.

Unable to reproduce the bug (in VirtualBox - low graphics mode, single monitor) so I can't verify the fix. Unable to switch to non-lowgfx because I get 'No such key 'lowgfx'' when trying to run `gsettings set com.canonical.Unity lowgfx false`.

=/ I'm also facing this issue. The curious part is that the issue happens more if I take a while to reboot the machine. I mean, if I don't reboot and just put the machine to sleep this issue start to happens more and more. I also realized that when I use two different users in the machine it also implies to happen more.
Sometimes just type ctrl+alt+f7 a couple of times works to bring the entry field back, but not always (as today), though, typing unity --replace in the user I had the GUI start it works. Last time I have this issue I was with two users logged in, so I just pkill -9 -u <user2> and the login entry screens backs to user1. Also happens to the login screen stay black just with the mouse pointer working.
