Ubuntu GNOME boots to black screen when using proprietary Nvidia drivers

[Manvydas]

To fix this now without waiting for the Stable Release Update
=============================================================
Install xserver-xorg-legacy

Impact
======
Many users are unable to use their computers after installing the NVIDIA proprietary drivers to Ubuntu GNOME. Specifically, the log in screen does not load.

The problem is that many of nvidia-* driver packages do not depend on xserver-xorg-legacy which is needed for gdm/gnome-shell to work

Test Case
=========
1. Check that gnome-shell depends on xserver-xorg-legacy.

2. Optionally, if you have an affected computer, set gdm as the default login manager (sudo apt install gdm3; sudo dpkg-reconfigure gdm3; sudo reboot). Does the login screen show up? And can you log in to gnome (sudo apt install gnome-shell)?

Regression Potential
====================
Low. Installing a missing dependency should cause no issues; if it does, something is very broken already.

Other Info
==========
The most minimal fix here for 16.04 LTS and 16.10 is to just have gnome-shell depend on xserver-xorg-legacy. Updating all the nvidia-* packages in Ubuntu and the PPAs would be a lot more trouble; although that would still be a good idea so that this gnome-shell dependency could be dropped in future Ubuntu releases.

xserver-xorg-legacy is a very small package.

gdm3 depends on gnome-shell.

Original Bug Report
===================
Using latest Ubuntu Gnome x64 daily build with all updates installed.
Lenovo Z70-80 laptop with Nvidia 840M, BIOS updated to latest version, secure boot and other potentially problematic BIOS settings disabled.

Can only see a black screen instead of a log-in screen after boot completes when proprietary Nvidia drivers are installed.
Regular Ubuntu works absolutely fine on the same machine with the same driver version. Attempting to use older drivers on Ubuntu Gnome made no difference.

Bug is affecting more than just me. We were talking about workarounds in ubuntuforums. User fthx claims that switching to lightdm fixes the issue http://ubuntuforums.org/showthread.php?t=2317628&p=13457703#post13457703

This change was made by a bot.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Francois Thirioux (fthx)]

I can confirm that lightdm+GnomeShell works without any Nvidia or Intel issue.
GDM fails.

[Tassos (tassos-chen)]

this bug affects me too, my laptop is Lenovo t440p with Nvidia 730M. Changing GDM to lightdm also works for me too.

[Tassos (tassos-chen)]

When I switch to tty1~tty6, the screen showed only one line: A start job is running for Hold until boot process finishes up( 56s/ no limit), and I can't do anything, even login to tty1...

[Alberto Salvia Novella (es20490446e)]

Please:

1. Report to (http://tinyurl.com/zzhjgjz).
2. Paste the new report link here.
3. Set this bug status back to "confirmed".

Thank you.

[Tim Lunn (darkxst)]

Alberto, this is probably not an upstream bug. the prime support is ubuntu specific.

I am not sure if this is fatal, but there is an error setting up prime offload, seems like the helper scripts are not getting called as root anymore.

[Tim Lunn (darkxst)]

Also can you attach /var/log/gpu-manager.log

[Tim Lunn (darkxst)]

Alberto,
   Any ideas on this one?

   The gdm PRIME scripts no longer seem to run as root, which I think was to do with the root-less Xorg work. Though that shouldn't otherwise affect the prime-offload script, right?

[Tassos (tassos-chen)]

my gpu-manager.log is almost the same as Manvydas's.

[Flames_in_Paradise (ellisistfroh-deactivatedaccount)]

Hey Tim,

it's just a guess, but could you try adding

iomem=relaxed

to the boot-parameter line? (Linux section, where you find the "quiet splash")

[Flames_in_Paradise (ellisistfroh-deactivatedaccount)]

@ TIm

The above mentioned just works in VirtuaBox.

Nvidia driver is using the new nvidia-drm and NOT module (nvidia.ko).

subscribing Alberto to look into that.

[Flames_in_Paradise (ellisistfroh-deactivatedaccount)]

Similar issue covered on Archlinux-bugbase:

https://bugs.archlinux.org/task/47140 ([bumblebee] can not handle nvidia-modeset.ko)

confirm same. reproducible on hardware Lenovo Yoga 500-15IBD Primus HD 5500/ Nvidia Geforce GT940M.

Bug

[Yaty Lee (ookong)]

Same to me. I have to rollback to Ubuntu Gnome 15.10. Please fix it.

[Alberto Milone (albertomilone)]

the log in comment #10 looks good to me.

@Tim: yes, it could be a problem with permissions. I don't use Gnome, so I didn't notice. I can certainly have a look at GDM.

@virgosun: that sounds like a different problem.

[Tim Lunn (darkxst)]

@Flames_in_paradise I do not have access to any optimus hardware to test.

@Alberto, Thanks, gdm does not run as root anymore, X is for now launched as root via Xwrap for NVIDIA, but once the nvidia KMS drivers land even that should not be required.

[virgosun (hdefendme)]

@Alberto Milone yet , 362 driver only works if the PRIME profile set to Intel Graphics power save. If the profile is set to NVIDIA Geforce then black screen after login. With Nouveu there is no way to turn of Nvidia GeForce. 16.04 in fact ruin the PC, toast it really heat.
Driver 351 run fine in 15.10 http://i.imgur.com/ubN15iq.jpg

[Alberto Milone (albertomilone)]

@virgosun: does 352 from the PPA work in 16.04? https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa

[virgosun (hdefendme)]

@Alberto Milone solve by add graphical ppa, nvidia 364.19

[Rick Gatewood (george-gatewood)]

This is a real show stopper for hybrid graphic laptop. I had to reinstall 15.10. I will be interested to see the fix for this one.

[virgosun (hdefendme)]

Rick Gatewood@ graphics ppa work for me, you can try. If you face back screen boot, then restart to recovery console:

mount -o remount,rw /
prime-select intel

If it don not work

apt-get purge nvidia*

If it work, login to desktop add graphic ppa address as @Alberto Milone.
On additional driver, choose Nvidia 364.19 (open source).
This work for me, PRIME profile work with both Intel and Nvida

[Simon Kjellberg (simonkberg)]

@virgosun just tried it with the latest open source driver (364) from graphics-drivers/ppa, and while selecting intel in prime works fine, after switching to nvidia and rebooting I'm faced with black screen again. Are you sure you're using gdm and not lightdm?

[virgosun (hdefendme)]

@Simon Kjellberg If 364.19 not work for you, you may try roll back to 352 as it work in 15.10.
I am sure it is gdm, I have almost naver been able to combine lightdm with Gnome in my system.
$dpkg-reconfigure gdm

[Tassos (tassos-chen)]

The latest open source driver (364.19) from graphics-drivers/ppa work for me now.

[Alberto Milone (albertomilone)]

one minor correction: 364.19 is not open source.

[Simon Kjellberg (simonkberg)]

@Alberto apologies. it's labeled as open source in software-properties-gtk http://i.imgur.com/7tgluHG.png

[virgosun (hdefendme)]

@Alberto Milone ah yet they said that it is just packed from the vendor's release

[shinyblue (shinyblue)]

Still have this problem while running 364.19 Tue Apr 19 14:15:03 PDT 2016

[virgosun (hdefendme)]

@shinyblue you can try different version from ppa, but remember to turn off Nvidia in bios before you are ready to turn it on.

Terminal upgrade and terminal recovery console is a very bare runtime without any power management. I was facing frequent force-reset while working in terminal, due to overheat

[Ameur Mohammed (ameur-mohamed)]

I was following daily build until one big update, then did this problem, I play Dotaz2 with nvidia drivers, I rolled back to 15.10, sad so sad, please fix ASAP

[shinyblue (shinyblue)]

Phew! Just done all 48 of these tests...

Tests:

1. GDM starts
2. Lightdm starts
3. Can launch Gnome
4. Can launch Gnome Classic
5. External monitor with Lightdm
6. External monitor with Gdm
7. External monitor with Gnome
8. External monitor with Gnome Classic

Results: . is fine, E is error (caused hang), F is fail but not hang. S is skipped, e.g. couldn't get to that test.

Variables:

- graphics driver
- prime select, one of:
  - intel (530 Skylake GT2)
  - NVIDIA Corporation GM107M [GeForce GTX 960M]

c6 364.19-0ubuntu0~gpu16.04.1 nvidia F.FF?SSS
---------------------------------------------------

## Config 1 ##

- 7:* Probably an E. I had it as a pass because when one monitor is ON it
  works, but having done the other tests I realised that the hang comes when
  two are turned on at once, which was not something I tested here.

- 5:E With monitor plugged in, working under Gnome, logging out to LightDm
  caused hang. Also booting to lightdm with hdmi monitor caused hang.

- 6:F. gdm goes blinky on laptop, unusable with external screen plugged in. See
  note below, seems to be the same problem: can't do two screens at once.
  Unplugging restores a working laptop screen.

- 8:F on test 8 first plugin of monitor caused blank screens. Unplug, replug gave
  an image on the external, laptop turned off. Nb. I had the 'Displays' config
  ui up the 2nd time I plugged in, not sure if this makes any difference. This
  is working. But trying to turn them both on at once resulted in a flashing
  unusable display on the laptop

## Config 2 ##

- 1:F gdm gives completely black screen. Can swap to tty, system not dead.

- 7:F both screens blank, laptop one twitches a bit. Removing cable brought
  back system.

- 8:F as 7:F, but when unplugged needed to swap to tty and back to get
  functioning mouse/interface.

- 6:F as for 1:F

## Config 3 ##

- 5:F lightdm goes all black/flickery when external monitor plugged in.
  Recoverable, though.

- 6:F gdm like lightdm when external monitor plugged in.

- 7:E, 8:E **gnome works on one screen**, but selecting both on causes a
  complete hang.

## Config 4 ##

- 1:F black screen. Pressing power button does cause normal shutdown

- 7:F both go black. Recovered after unplug.

- 8:F as 7:F

## Config 5 ##

- 6:F flashy screen, mostly blank. Removing cable (quickly) brought stability.

- 7:E, 8:E ext. monitor works but hang if 2 displays at once.

## Config 6 ##

Was all the same.

## Conclusions ##

- GDM: intel only across the three drivers.

- Gnome/Gnome classic behave the same.

- Two monitors:

  - both on: you just can't have it with gnome. (lightdm works, and previously
    I had Unity working, too)

  - one on: works with intel, not nvidia.

[Jonathan Hartley (tartley)]

@shinyblue: Very nice work.

Does the ticket title need updating to reflect it isn't just Nvidia drivers?

[Ameur Mohammed (ameur-mohamed)]

This is a valid problem, each time I enable nvidia, I can't login, no GDM or GDM3, I can't play Dota 2, please fix

[Bruce Pieterse (octoquad)]

I just upgraded my Acer Aspire V3-771G with Nvidia GeForce GT630M to 16.04 from 15.10. What I found was the following:

1. If booting with the splash quiet options in GRUB you will get "A start job is running for Hold until boot process finishes up ( 1s / no limit)" on all tty's. Without these parameters in GRUB, you have access to tty1-7 again, which allows for a little more debugging.
2. With the splash and quiet options in GRUB both tty 1 and tty 7 show a black screen. Without these options only tty7 is affected.
3. Removing all nvidia packages with sudo apt-get remove --purge nvidia* and then rebooting works (here I am typing this :)
4. nvidia-340, -346, -352 & -361 always renders a black screen for me. I did not try -331 or -331.
5. If you boot without the splash and quiet options in GRUB, run journalctl -f in one tty and then run systemctl restart gdm.service in another tty I get a segfault in gnome-shell "kernel: gnome-shell[3423]: segfault at 14 ip 00007f893e9a4035 sp 00007ffc392b09f0 error 4 in libmutter.so.0.0.0[7f893e96a000+f2000]"

I have attached journal output from the time I restarted gdm in a tty which might have some other info.

[Tim Lunn (darkxst)]

Bruce, can you file a crash report bug for the segfault so we get a backtrace?

[Tim Lunn (darkxst)]

shinyblue, probably best to file a seperate bug for the external monitor issues

[shinyblue (shinyblue)]

Hey Tim, yes I already did that https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1559308

Just included the results here for completeness.

[Bruce Pieterse (octoquad)]

Stacktrace attached.

I modified the LOG variable in /sbin/prime-offload to /tmp/prime-offload.log as well as adding xrandr -q >> $LOG 2>&1 as per darkxst suggestion and only get one line logged: Screen 0: minimum 8 x 8, current 8 x 8, maximum 16384 x 16384

[Tim Lunn (darkxst)]

[Ameur Mohammed (ameur-mohamed)]

Any update on this bug?

[Crystal Paladin (britty-it)]

Even after installing proprietary,tested nvidia drivers for gforce 630M, this issue pops up...

as of now, did a

sudo apt-get remove nvidia*

till this issue is fixed, I'm not gonna update my nvidia drivers

currently running on noveau

[Crystal Paladin (britty-it)]

I hope we need not "apt-get remove --purge". "purge" is not necessary as the issue might be with gdm alone and the next time we choose the nvidia drivers, it'll use the one already downloaded instead of downloading it once again

Hi,
Looks like we may have a problem with Intel users after all.
I checked the difference between xubuntu and lubuntu ISO, and this
package is missing :
xserver-xorg-video-intel
Intel cards was supposed to work without this package, but according
to the package description, it is only the case for new cards.
If you have people affected by black screen, or no X starting, or no
lightdm starting, with Intel card, could you advise them to install
this package, reboot, and see if it's working (and report back) ?
This should affect only fresh install, upgrade should be fine (as this
package was included in previous releases).
Thanks in advance for your reports.
Regards,
Julien Lavergne "

The problem there seems to be on lubuntu, but maybe it could be the same root problem for gnome. I could not test it yet. Would somebody verify this?

[Tim Lunn (darkxst)]

we do have that package on our ISO's so not likely related. Also pretty sure Nvidia PRIME uses the modesetting driver for intel, not the above mentioned.

[fanl (felipelav)]

Tested with nvidia-364 from the ppa:graphics-driver/ppa with gnome 3.18 and
ubuntu 16 and nvidia-prime with nvidia selected as gpu. It logged in fine,
didn't test further.

[Nuno (nmrcardoso)]

Ubuntu 16.04 with nvidia drivers 361 and 364 are NOT working here either in a laptop with intel and nvidia GeForce 940M.
Using either these drivers and nvidia-prime, its installs and works at first graphical boot, after a few minutes the system freezes and only after a hard reset the drivers don't work anymore.
Also, I only managed to get working the driver 361 with bumblebee, however after a suspend the nvidia card cannot be used getting a error of fallen off the bus and the message refused to change state...

In conclusion, these drivers are NOT WORKING!!!!!

I only get the system perfectly working using the 352 drivers and nvidia-prime, the install of the 352 nvidia driver is not working through apt-get and ppa:graphics-driver/ppa,
I had to manually download them from the site and install them manually.

Please fix these!!!!!!!!!!!!!!!
Or at least give the people the option to install the 352 drivers through the Additional Drivers in Software and updates.

[Ameur Mohammed (ameur-mohamed)]

Thank you Nuno (nmrcardoso), well said, that's exactly what is happening

[Simon Kjellberg (simonkberg)]

Interesting, I just tried again on a clean install and the latest nvidia-364 driver from ppa:graphics-drivers/ppa is working fine with nvidia selected in prime now.

[Tim Lunn (darkxst)]

Alvin, please don't change the bug status unless you plan to fix this bug ;) thanks!

[Ameur Mohammed (ameur-mohamed)]

I confirm, after a clean install again, everything is working, I think this was an Nvidia driver bug not gnome gdm3, as follows my system configuration:

ubuntu gnome 16.04
Kernel: 4.4.0-22-generic
nvidia driver: 367.18 installed from ppa:graphics-drivers/ppa
my gpu is: GeForce GT 740M
running on HP ENVY Laptop

Every thing is working fine, thank you all for your support

[P.R. van Puijenbroek (peepjuh)]

Without a fresh install the 367.18 driver (from ppa:graphics-drivers/ppa) does allow me to boot (no hanging on tty or login loop). But nvidia-settings appear empty (something like http://i.stack.imgur.com/H9EBt.png). I also have a secondary monitor connected over HDMI which is not being detected at all. Xandr is not even listing the HDMI port.

[Ameur Mohammed (ameur-mohamed)]

Sadly... I'm back to 15.10, don't know what happened but it suddenly stopped booting with Nvidia,

with this configuration

ubuntu gnome 16.04

Is not working again

[Ivan Frederiks (idfred)]

I found out that 'nouveau' driver comes with linux-image-extra package and prevents 'nvidia' driver from being loaded. I blacklisted nouveau:
$ sudo -i
# echo "blacklist nouveau" > /etc/modprobe.d/blacklist-nouveau.conf
# update-initramfs -u -k all
# reboot
Finally everything works for me!

[Henri Cook (henricook)]

After removing nvidia-364 and installing nvidia-367(.18) from a TTY before rebooting I still cannot get my external monitor to work. When I connect it via HDMI it flickers a lot and unless I unplug the HDMI after the first couple of flickers goes completely black.

ubuntu gnome 16.04
Kernel: 4.4.0-22-generic
nvidia driver: 367.18 installed from ppa:graphics-drivers/ppa

running on: Dell XPS 15 (9550)

Happy to try and help anyone debug, catch me on IRC - ph8

[Crystal Paladin (britty-it)]

blacklisting noveau doesn't sound like a good idea... when anything goes berserk with my graphics driver, I always revert to noveau and things will be come stable (though not perfect) but everything will atleast work...

abandoning noveau might leave you in between a rock and a hardplace

[Henri Cook (henricook)]

Actually looking at what nvidia-367 does it adds its own nouveau blacklist, so if you have these packages you probably already have one in there. Which I guess is why all the "manual reset from the TTY" guides make sure you do a full purge of nvidia-* before attempting to reboot into nouveau

[Vishwa Prakash H V (severustux)]

My problem details : http://askubuntu.com/questions/778300/installing-nvidia-graphics-drivers-on-ubuntu-gnome-16-04/780950#780950

I tried Nvidia-364 and Nvidia-367 from ppa:graphics-drivers/ppa , It results in login loop when switched to Intel in Nvidia prime.

[Simon Kjellberg (simonkberg)]

soo the latest update to nvidia-367 (uploaded 17 hours ago) re-surfaced this issue for me. couldn't even get to the login screen, just stuck in a loop with a tty flashing. had the intel driver selected in nvidia-prime.

i also can't remove libcuda1-367 now:

[Henri Cook (henricook)]

Noticed a 367 update today, this problem still persists

[timkofu (makobu-mwambiriro)]

Confirming installing the 364.19 driver from the “Graphics Drivers Team” team PPA fixes it on Ubuntu-Gnome 16.04 on a Dell Inspiron 5558 (Nvidia GeForce 920M (Optimus))

[Henri Cook (henricook)]

timkofu, would you mind telling us about your system? I haven't had success with those drivers, i still just get flickering and then an eventual X crash when trying to connect an external screen to my XPS

[timkofu (makobu-mwambiriro)]

@henri; I was having the same issues, then I did a clean install and installed all system updates, then added the PPA and installed the driver from "Additional Drivers".

[Stephen Cox (stephen-cox)]

Installing the Graphics Drivers Team 364.19 driver doesn't fix the problem on a Dell XPS 15 9550 when using the Nvidia GPU, but things are a bit different. Before I would only get a black screen when logging in, but now I get a largely back screen with some random looking vertical lines. Things work fine on this driver when using the Intel GPU.

[Frank Feuerbacher (drw06g0w7-frank)]

I am seeing the same behavior with a Dell Precision 3420 (Service Tag 318HFB2). No NVIDIA, just i7-6700 HD430, 1 or 2 monitors turned on.

Worked fine using defaualt DM (Unity) then installed gnome-shell and it broke.

[Starbeamrainbowlabs (sbrl)]

@#74 Are you sure? Are you using the proprietary drivers for your GPU or the nouveau drivers?

Also unrelated to the above I managed to get my NVidia 525M working by installing the 364 drivers *and* rolling the kernel back to 4.2.x. One or the other didn't work IIRC - you have to roll back both.

[Tim Lunn (darkxst)]

Frank,
   If you have no NVIDIA GPU please file a new bug, that will be a different issue to what we are tracking in this bug.

Run `ubuntu-bug gnome-shell`.

[FNM (mfouze)]

Same issue on my laptop ( Asus G501VW ) I have installed
"NDIDIA binary driver - Version 367.27 from nvidia-367"

However, while I was searching for a solution my computer with the issue, automatically locked itself (I have set it to lock the screen and turn if off after 5 mins) when I moved the mouse it woke up, but this time, I could see the screen.

I tried this after several restarts and it works, and no it does not work if I move the mouse under 5 mins. So it has to be the screen lock.

[Simon Bursten (smnbursten)]

I had the same issue on my Asus N552VX laptop. Installing 367.27 from nvidia-367 worked fine after running prime-select intel but prime-select nvidia would lead to the login loop issue people have noted here. Once logged in via the intel graphics option nvidia-settings wouldn't load.

nvidia-xconfig
dpkg-reconfigure gdm3

from Ctrl + Alt + F1 shell fixed the issue for me. The driver is still broken as multiple screens don't work under nvidia mode, but I can get away with playing games under nvidia mode and working under intel mode.

[Diego Medeiros (xeolhades)]

Same here on Dell Inspiron 3421 i5 with NVIDIA GeForce GT625M 1GB.

[Patrick Vanguardia (pvanguardia)]

I am experiencing the same on HP EliteDesk 800 G2 SFF. Tried everything goes to loop and sometimes blank screen.

[Martin Höger (martin-hoger)]

Very similar for me with Acer V 15 Nitro with NVIDIA GTX 960M. When a display is plugged via HDMI black screen is present. When the GPU is set in prime settings (nvidia-settings) to Intel, everything works. Lightdm didn't help.

Ubuntu 16.04 LTS, driver 367.27, Ubuntu 4.4.0-28.47-generic 4.4.13

[Clemens Gersbacher (clemens-gersbacher)]

Hello,

I experienced the same problem on my new HP Pavillion 15 with nvidia 950M graphic card. After switching to nvidia driver the system boots into a black screen. So I started playing around a little...

I've installed Ubuntu Gnome 16.04.01 and it ran fine with nouveau driver -> system worked.
Switched to nvidia driver -> black screen.

Installed Ubuntu 16.04.01 with unity running nouveau -> system worked.
Switched to nvidia driver -> system still worked!
Installed ubuntu-gnome-desktop with gdm3 -> black screen.

Installed Ubuntu 16.04.01 again.
Switched to nvidia driver -> worked fine.
Installed ubuntu-gnome-desktop with lightdm -> worked! :)

[Francois Thirioux (fthx)]

Still affects Yakkety with GS 3.20 packages. Same workaround works.

[Fred Zelastian (fredzelast)]

Tried to install Ubuntu Gnome 16.04.1 with NVIDIA Driver 367.xx using the GDM display manager yesterday and resulted in black screen at login.

Did the same today with the newly released NVIDIA Driver 370.23 (beta, I think) and everything is actually working fine - no black screens, but the login seemed kinda funky. Although there don't appear to be any technical issues so far, I'm not entirely sure if that NVIDIA Driver build is stable. Not sure if it's just affecting me either, but thought I'd throw that comment in there.

[Francois Thirioux (fthx)]

Indeed, I get the same experience with Yakkety.
"Kinda funky" means, running my system, that Nvidia boots fine but Intel can lead to a login loop (not reproduced) and surely to a Xorg crash (but only Apport makes me knowing that there is one, except maybe the deactivation of some Gnome shell's extensions).

[redshift (bjchip)]

Add me to the users for whom lightdm worked.

gdm runs, appears and on shutdown (service gdm stop) appears to be doing some sort of a loop of the NVIDIA Persistence Daemon... the daemon leaves a screen message that is hidden until the stop breaks in on it.

The system is an older ASUS P5G41MLX with a core-duo quad and 16 GB of ram.

Reinstalling NVIDA, GDM, Installing intel micro-code and repeated restarts/resets did not get past this last step on the screen

Sep 3 08:13:42 occam systemd[1]: Starting User Manager for UID 118...
Sep 3 08:13:42 occam systemd[1]: Started Session c1 of user gdm.

This is by observation the last step prior to presenting the gdm user menus.

I am including the kernel log for the machine. This doesn't clearly identify the problem but it does show several logs that cannot be created. I have the lightdm working and am loath to break it all again to collect those logs but I am going to create them and make them writable.

The gdm issue seems not to be

An older NVIDIA card had no problem but hadn't had the NVIDIA drivers installed. The new card is a 1060.

The GDM process IS running there.

[Francois Thirioux (fthx)]

Some adds, running Yakkety with official 367.44 driver :
* running Intel, select Nvidia, logout/login, login loop
* running Nvidia, select Intel, logout/login, login loop
* running A, select B, restart, Gnome starts normally

Maybe that some progress in my previous message were due to non-unloading Nvidia driver (which was a bug) when using Intel, but I really don't know if it is related.

[RamL (ram4444)]

Similar issue for Dual Discrete Display card AMD+GeForce

I wanna blacklist nouveau for the Geforce VGA Passthrough via VFIO
but then the screen on ATI is flickering on the tty login screen but not to Gnome. The keyboard NUM lock light is flickering as well and it is hard to work for typing the password
After flickering for a while, my keyboard works normally and I can login in command line.

However the screen flickers again when I type service gdm restart, I still fail to get in GNOME.

[Roderic Jones (rodericj)]

This happens to me on a desktop with Nvidia GTX 750 ti. Installing 16.10 works until the driver is installed and then it is no longer bootable. The solution is to use the older driver. You are offered 361.42 (which causes the problem) but the other one 340.96 works fine.

Incidentally Ubuntu 16.10 on another ssd uses 361.42 which is also fine

[Roderic Jones (rodericj)]

I just noticed a typo. Ubuntu 16.04 uses 361.42 which is fine

[Antony Karlytzky (arihiza)]

This is happening to me too. Cannot boot when nvidia-prime is set to nvidia. While set to intel it's fine.

[Dimitrije Petrovic (mitap94)]

This happened to me too. Installed Ubuntu Gnome 16.04.1 yesterday, installed the 361 NVIDIA driver (I think) for the 840M card and boot into black screen. All ttys showed: A start job is running for Hold until boot process finishes up.

[Roger (r-wiberg)]

Bug #1632322 - about computers with _only_ an NVIDIA card refusing to boot with proprietary drivers, because of GDM3 - was declared a duplicate of this bug yesterday and further discussion was to be conducted here. Hence my posting here to point out that bug #1632322 is _not_ a duplicate.

Bug #1632322 is about GDM3 as such not playing nice with NVIDIA. It has nothing to with Optimus. And it doesn't concern "hybrid (prime) systems", which is the bug referenced in the release notes on https://wiki.ubuntu.com/YakketyYak/ReleaseNotes/UbuntuGNOME#Known_Bugs.

So could bug #1632322 be reopened, please? And possibly even looked at before release?

[Subham Satyajeet (subhamsatyajeet)]

Can confirm. Ubuntu GNOME 16.04, fresh install, Nvidia 361 drivers not working. Has somebody made any progress on the bug?

[René (rkerner+)]

Hello, I had the same problem, but I could solved my case:
Gigabyte Notebook with hybrid Intel + Nvidia GTX 765M card with PRIME not working with (K)Ubuntu 16.04 with any version of the proprietary NVIDIA driver. When prime-select switched to nvidia gives a black screen, set to intel worked. NVidia proprietary driver prime-select set to nvidia worked on (K)Ubuntu 14.04 before.

The solution that worked for me (with latest stable driver 367.57, from graphics ppa, but should work with every driver) was to change xorg.conf!

The version of Xorg shipped with (K)Ubuntu 16.04 is 1.18.4, where the BusID format in xorg.conf was slightly changed in Xorg >= 1.17.2.
I changed `BusID "PCI:1@0:0:0"` on the nvidia card to `BusID "PCI:1::0:0"` and similar process on the intel section and also added the LoadModule setting. Like described in an answer to a post on askubuntu. see: http://askubuntu.com/a/776527

I guess the broken id works on PRIME set to intel because autodetection in single-intel mode is much better then the Nvidia PRIME stuff.

After restart it worked, but something changed my xorg.conf again to have invalid data. I'm now experimenting with deactivating gpu-manager by commenting all lines in /etc/init/gpu-manager.conf (see https://vxlabs.com/2015/02/05/solving-the-ubuntu-14-04-nvidia-346-nvidia-prime-black-screen-issue/ ) and setting "chattr +i" for xorg.conf.

and see ArchWiki: https://wiki.archlinux.org/index.php/NVIDIA_Optimus#Using_nvidia

Hope this solves your problems with NVidia PRIME too!

[Sergio Mattei (ftxrc)]

Any progress on this issue? It has rendered my Alienware Alpha Ubuntu GNOME installation unusable, and I have to use Noveau now which is not acceptable for OpenCL apps. Any help?

GDM works only with nvidia-340.

[Alexander Adam (7ql6)]

Having the same problem on Unity and Ubuntu 16.10. Regardless which of the prorpietary drivers I use (367, 370, 375) it will result in a black screen. Intel card works flawlessly though.

[Jacques Serfontein (jacques-serfontein)]

Running Ubuntu Gnome 16.10 with official repos only. No problem with 340.98, but I had the same issue with 367.57, until I reinstalled xserver-xorg-legacy, which was removed along with the old packages...

[Žygimantas Beručka (zygis)]

Similarly to comment #74, I have exactly the same symptoms on a Samsung laptop with Intel HD4000 graphics (i.e. *no* nVidia or any other video card is/was present). Moreover, it's a fresh install of Ubuntu 16.10. It is also of note that I've never had this issue before on the same machine with any of previous versions of Ubuntu Gnome, including 16.04 LTS with gnome3 ppa enabled.

On 16.10, I just cannot properly start GDM3 at all. It shows the same black/dark grey background as has been mentioned and nothing else is going on. Also, going to TTY1 does not work -- one is unable to do anything on it; even CTRL-C does not work. Switching to TTY2, however, works fine. I've looked at various log files, but to be honest, I don't see any clues indicating what's the problem and where the process gets stuck.

It works just fine with LightDM, though.

[Žygimantas Beručka (zygis)]

Well, I just did discovered something by accident. I *DID* manage to start GDM3 just by executing 'gdm3' as *root* from a TTY. I am now able to login just fine and GNOME works fine.

Launching GDM as a service (systemctl) does not work, though. Why is this so? And what can I do to resolve the issue?

[Alessandro Scarozza (xan.scale)]

lightdm + lightdm-gtk-greeter works FINE.

why not replace GDM with this?

[Giuseppe Pennisi (giupenni78)]

Same problem. I think is not acceptable that this bug is still present.

[amk (9-launchpad-mikus-sk)]

lightdm-gtk-greeter does not work fine... no visual countdown/other display of the autologin timeout. See https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/902852/comments/31

XDM also does not allow to cancel autologin before the time elapses.

[Jacques Serfontein (jacques-serfontein)]

To follow up on #100, I have been running 375.26 from graphics-drivers PPA without any issues for a couple of weeks now.

[jack (hyyyde)]

Fix it with lightdm + lightdm-gtk-greeter

On Ubuntu Gnome 16.10 with kernel 4.8.0-37-generic and driver nvidia-378

[RobertFM (robert123m+ubuntu)]

Thanks to #100 I got GDM working again.

I just upgraded to nvidia-378 and re-installed xserver-xorg-legacy and finally got GDM working again.

I'll keep lightdm installed just in case it all stops working again.

I don't know/remember if this happend while I was fiddling around getting GDM to work. But in /etc/gdm3/custom.conf I had the following line active and it was running havok with GDM opening in different tty every boot an delaying boot time. So make sure to comment out the following line:

#AutomaticLoginEnable=True

[RobertFM (robert123m+ubuntu)]

Ps. It is working on Ubuntu 16.10, 4.8.0-39-generic, GDM3 3.20.1-1ubuntu2, nvidia-378

[Stein Erik Svendheim (svendheim)]

Same here. #100 fixed it.

apt install xserver-xorg-legacy did the trick. I am using nvida-378 from the graphics PPA.

[Tim Lunn (darkxst)]

>> The most minimal fix here for 16.04 LTS and 16.10 is to just have gnome-shell depend on xserver-xorg-legacy. Updating all the nvidia-* packages in Ubuntu and the PPAs would be a lot more trouble; although that would still be a good idea so that this gnome-shell dependency could be dropped in future Ubuntu releases.

That seems like a bad idea to me, you will break root-less Xorg for all other users that don't even use nvidia drivers. The dependency needs to come from the nvidia driver packages even if it is a Pain to update all those.

That said what is the current state of Nvidia KMS implementation? I would have though recent nvidia drivers would support root-less xorg, but havent had a chance to play with any nvidia hardware since last winter.

[Jeremy Bícha (jbicha)]

Tim, thanks for commenting.

How common is root-less Xorg?

Should there be a warning in xserver-xorg-legacy's description that it can break things?

Would having gnome-shell recommend xserver-xorg-legacy be ok? It may take Alberto some time to update all those packages so I was hoping for a faster, more minimal fix here.

I don't know much about Nvidia. Apparently, Nvidia on Wayland on Ubuntu 17.04's GNOME 3.24 mostly works now (LP: #1666664).

[Tim Lunn (darkxst)]

It has been used by default since 16.04 and is supported by all major open drivers including vbox/vmware, so its rather widespread.

Obviously having Xorg run as the user account instead of root is big win for avoiding security issues within Xorg. It wouldnt hurt to have some sort of description about the security risks in xserver-xorg-legacy.

Adding -legacy temporarily is probably ok, but get it off the images again before release.

rootless X is somewhat orthoganal to wayland support in respect to EGL Streams, but I would assume the KMS modesetting support required for Xorg must be there if wayland has got that far.

[Jeremy Bícha (jbicha)]

Tim, can you look into this more?

If I understand the manpage correctly, xserver-xorg-legacy should still do the right thing where KMS is available.

https://manpages.debian.org/unstable/xserver-xorg-legacy/Xorg.wrap

I had the pending SRUs rejected from the unapproved queue for now.

[Tim Lunn (darkxst)]

on my laptop (zesty w/ intel) without -legacy, Xorg runs as my user account. once I install legacy it runs as root. I tried adding needs_root_rights=auto to Xwrapper.config but its still running as root.

So perhaps the autodetection is broken for some reason.

Bruce, it's not really Fixed in Xenial yet. If you take Ubuntu GNOME and install the Nvidia proprietary drivers, your computer might fail to show the login screen the next time you reboot. Yes, you can manually install the missing package but it needs to be handled automatically. (It's installed by the 304 and 340 packages but not newer ones.)

[Kevin Norman (kn100)]

Can confirm that without xserver-xorg-legacy my system will refuse to boot when using GDM. It will simply sit at a black screen, never allowing me to log in. With the package installed, GDM seems to work correctly.

Another interesting nugget of information is my initial fix was to simply use lightdm. This introduces another bug whereby on login the display will briefly (for around 5 seconds) show either:
a) Pink/white garbled mess
b) If I've been logged in recently, what I had on my screen previously. This is even the case if I am booted into another operating system like Windows and then reboot into Ubuntu GNOME.

I am using a Nvidia 660ti (GK104) with the Nvidia drivers (375.39).

If I can provide any helpful information to the developers, please let me know. I am happy to dump whatever logs are necessary.

Status changed to 'Confirmed' because the bug affects multiple users.

      o GeForce GTX 1080 Ti
      o Quadro P3000
      o Quadro M520
      o TITAN Xp
    - Fixed a bug that could cause EGL applications to crash when
      calling eglInitialize() multiple times on X11-backed displays.
    - Fixed a regression that could cause rendering corruption on a
      monitor connected via DisplayPort upon a modeset event (for
      example, changing resolutions or power cycling the monitor).
    - Fixed a bug that could cause OpenGL applications to crash when
      VT switching between multiple X servers.
    - Fixed a bug that caused the system to become unresponsive after
      resuming from power management suspend/hibernate.  Additional
      symptoms of this bug included display flickering and "Xid 56"
      errors in the kernel log.
    - Fixed a bug that caused backlight brightness to not be
      controllable on some notebooks with DisplayPort internal
      panels.
    - Fixed a bug that left HDMI and DisplayPort audio muted after a
      framebuffer console mode was restored. For some displays, this
      caused the display to remain blank.
    - Fixed a bug that caused audio over DisplayPort to stop working
      when the monitor was unplugged and plugged back in or awoken
      from DPMS power-saving mode.
    - Restored support for the following GPU:
      GRID K520
    - Fixed a regression that caused corruption in certain

As someone who confirmed this bug really early on, and has suffered from it for ages i'm here to say thanks for the fix!

I have two systems that were suffering from the problem, on one a yakkety -> zesty upgrade fixed the issue and on another a new zesty install also did not experience the problem*

[Abdulrahman Amri (amri)]

I am having the same issue on Ubuntu 17.10 with gdm3.

- Lightdm works
- Nouveau driver works
- Nvidia driver 375.66 (proprietary) does not work
- Nvidia driver 384.47 (open source) does not work
- Nvidia drivers work with Ubuntu Gnome 17.04

[Daniel van Vugt (vanvugt)]

This bug is closed, rightly or wrongly. So if you have any ongoing issues with 17.10 then please open a new bug.

[Tim Richardson (tim-richardson)]

I have the same symptoms as this bug with 17.04 and the new 375.82 driver if I am use modesetting with gdm. With lightdm it works fine.

[Daniel van Vugt (vanvugt)]

This bug is closed. For ongoing discussions (and a solution), please see bug 1705369 instead.

[Daniel van Vugt (vanvugt)]

Or see bug 1706474 which you logged, thanks :)

[shantanu saha (shantanucse18-gmail)]

I have tested with nvidia-384 and 387, issue is not fixed with gdm3. Lightdm works fine.

[Daniel van Vugt (vanvugt)]

This bug is closed, rightly or wrongly. Adding new comments here won't lead to any new resolution. The best thing to do now is to log a new bug.
