Bug Description
Binary package hint: udev (but not quite sure)
On my Lenovo T60 the Touchpad works great until I login using GDM.
After 2-3 seconds I've pressed "Login" it suddenly stops working and I must use an external USB mouse.
I'm using Lucid Lynx Beta1.

Christ, thanks for your efforts.
Sadly your solution doesn't work with me. I tried rebooting, I added touchfreeze to the startup applications, turned the touchpad on and off on both touchfreeze and Fn + F7. All to no avail.
I hope there's an other way to do this :S This obviously must be fixed before release. It looks until now as if every touchpad has this...

For some reason, this bug stopped affecting me. Maybe the gnome version that recently came through the update manager fixes this?

This is not working for me. I had the problem start about 3 days ago (4/14?) after applying updates. The pointer started shaking and being unresponsive. I rebooted and the touchpad worked until I logged in. After some troubleshooting I created another user account and the touch pad works in that account.
I think this is probably due to corruption or mis-configuration of a user level configuration, but I have not been able to find information about user specific config files that reference touchpad settings. Toggleing TouchpadOff with synclient does not seem to have any effect, but I don't know if I need to restart a service or whatnot to get the new setting to take effect. After logging back in it reverts back to 0.
Exiting and entering Xwindows and applying other packages per #10 did not help.
I am working with an HP Touchsmart tx2, running 10.04 beta2, amd64, applying the latest patches daily. If I can provide any more information let me know.
Alternatively if anyone can point me to config files to look at it would help greatly. I really feel like a user level configuration simply toggled the touchpad off.

This bug appears to come and go randomly. A few days back it suddenly stopped working when logging in, the day after (or a reboot, can't remember) it worked again.
BTW, I heard that Synaptic was bussy on (proprietary) drivers for the touchpads to enable multi-touch on Linux :D Pity they are proprietary though... But hopefully, those drivers will show the open source drivers developers how to solve that :) Has nothing to do with the bug though. Just something that popped up in my mind.

- workaround Edit (62 bytes, text/x-sh)
The file in the workaround does not exist. In Lucid, apparently, that file has been judged obsolete and been removed. There's probably a file which does the same, or some other workaround that will do this every boot.
I attached an .sh file for the convenience, and I changed 'sudo' to 'gksudo' so you'll get a graphical interface question for the root password instead of a commandline version. You can download it in your /home directory, and make it run every boot by going to System -> Preferences -> Startup Applications and click on 'Add'. Type anything in the name section, and type this command in the command section: sh ~/workaround.sh
I don't know whether this works though. I don't have this bug anymore for some strange reason (without workaround). So I can't test it... And again, the workaround is not mine.

This happens to me too on a HP Pavilion dv9000 (dv9845ed) but I have some additional info:
When I boot up with the touchpad disabled, I can use my external USB mouse to login.
The external mouse works fine and I can do everything, however....
When I now activate the touchpad, my mouse stops working too!!! and the touchpad is not working correctly either. I can disable the touchpad again, but the mouse still does not work properly. I can use the right mouse button (see context sensitive menus, etc.) but the left mouse button does nothing.
The only thing I can do is use ctrl-alt-delete, click with my external mouse on suspend, then the button gets highlighted (so it does see a mouse event) but it does not trigger the action!!! I have to press the 'enter' key to really put it in suspend.
After waking up from suspend, everything works normal again.
I have tried the 'sudo rmmod.......' commands, and they seem to fix this problem, but I have only tried this a few times now. It's also not a real solution because now I have to run a script everytime I login to prevent my mouse/touchpad from becoming unresponsive.
If anyone has an idea / suggestion how I can give more info which can help, pls let me know.

Haksell's fix (#50) works, but only in the strictest sense of the word. It's touchpad functionality at it's most basic, is unaccelerated, and side scrolling is disabled. Further, touchpad configuration becomes disabled in the GUI configuration tool.
Have we removed the "Fix released" status? Because this bug is continuing to wreak havoc for multiple varieties of touchpad on multiple varieties of laptop.

Yes I do agree, this is not a module related issue... That works, but it's just an huge workaround.
The only way I can make my touchpad and my touchpad-button to work is to invert the "/desktop/
I guess that this all due to the fact that the above setting is inverted at the beginning of a session (so, using the hardware button you enable the touchpad, but you disable gnome to grab its values and vice-versa).

Same Computer as Morten Minke (It's a Co-workers HP dv9000) and same symptoms, including the inability to left click.
Fresh install of release version of 10.04LTS (never had any Ubuntu/Linux before, whole hd for Ubuntu), problem not present or not noticed until after doing the updates.
Switching to a psuedo term and back sometimes seems to fix it.
Also, due to some other problems, the keychain password and login password were out of sync. This seemed to be when the problem started, and seems to have been fixed when either I fixed this, or when I did:
gconftool -s /desktop/
Not sure if the keychain stuff is relevant, but Gnome is so integrated with everything these days. Perhaps it thinks my input device preferences should be secret.
Interestingly, I have rebooted, and completely shutdown several times, and it now seems fine without doing the gconftool line again.

I just noticed this problem tonight. I'm not sure how long its been going on for, I normally use a USB mouse. Using a HP dv5z-1000 with the 64 bit version of Lucid and all the latest updates. I just tried switching terminals and switching back like Linuxslate suggested, and its working at least for now. Seems like this should be a fairly high priority if its affecting as many different people and systems as it seems to be, especially since on a laptop, you often don't have a way to use a conventional usb mouse.

Confirmed still a problem on Lucid. I suspect the culprit was an updated "laptop-detect" package, but I have no evidence to back that up.
Doing this did solve the problem:

I used gconf-editor to make the change graphically.

I upgraded from Ubuntu 9.10 to Ubuntu 10.04.
The touchpad worked fine for a while, but then odd things started happening. Occasionally I would get this problem where the right-click would stop working, then only the left click would work but I could only click on certain things (I couldn't open the applications menu with left-click). At the same time this happens, my keyboard becomes unresponsive, and the problem would only go away if I turned off the power.
But then these problems started occurring soon after I logged in. Now my touchpad only works for a couple of seconds after I've logged in.
I'm not sure if all these bugs are related, but I thought I'd mention them just in case.

Ok, I figured out that those problems only occurred after I pressed the touchpad on/off button.
If I press this button, the keyboard becomes unresponsive and for some reason I can't do anything except left-click on tasks in the taskbar using the mouse (the applications menu doesn't open even whether I click on it or press alt+f3).
The thing in #42 works, but if I press the touchpad on/off button then everything stops working, so I can't turn off the touchpad when I don't want to use it.

When there is no WiFi connection, the touchpad works better, but still freezes time to time.
Without touchpad the following workaround gets it back to life:
gconftool -s /desktop/
gconftool -s /desktop/
After that I also have to do some dancing with the desktop/windows switching to resume it.
But usually the touchpad freezes when I press a button on it.
When WiFi is connected, everything looks like a catastrophe.
It even disapears from "xinput list".
And in both cases it receives no events when I start "xev".

3) removed all nvidia and radeon tools - maybe not mandatory
4) booted in recovery mode and regenerated Xorg.conf.
Now I work with the touchpad more then an hour without any troubles.
Tried to reboot, etc.
So far so good. Hope it helps others.

Tried almost everything! So far my touchpad works without any problems!
After having so big problems with it, I'm trying to avoid saying that this is the best solution, but:
I think the problem isn't in xserver-
Just try this solution and let me know if it works for you.
I've upgraded my Samsung N210 from Ubuntu 9.10 and after the update a week ago had a lot of problems with touchpad.
And now it looks good, so far.

LinuxMint 9 user here, I found in one of the threads under Ubuntu forum about this code you have to type in the terminal:

after tying this in the terminal, my touchpad is alive! not sure if it will comeback after I restart though...

I'm sad to say that the problem is back on my Samsung NP-N210.
I've googled through many articles, tried many changes, but problem still occurs.
To be more exact, it gets OK sometimes, and sometimes following actions help:
gconftool -s /desktop/
gconftool -s /desktop/
sudo modprobe -r mouse
sudo modprobe -r psmouse
if I run "syndaemon", I receive the message "Unable to find a synaptics device."
Tried to change xorg.conf file with many ways, but successful.
What I also tried is to set "TouchPad" as "AlwaysCore" in xorg.conf, it helped for some time but then the problem was back.
Done the fresh install of Ubuntu 10.04 from USB, formatted drive, but useless.
Donno what to do. Confused, frustrated,,,
The module is loaded according to Xorg.0.log:

And then it's reloaded:

But then it's unloaded:

But sometimes, when the messages are the same in the log file, the touchpad is functioning.
Really unpredictable behavior.
Finally I bought wireless mouse and it has solved my issue without the touchpad.

I first tried it by modifying the command line. Select the desired kernel and then press 'e' at the grub menu and add "i8042.reset i8042.nomux" (without quotes) just before the "quiet noplash" parameters. Once I determined that this worked, I made it permanent by modifying the GRUB_CMDLINE_

I too experience this problem since a few days, probably after an update. At home I always use a mouse, so I did not notice until recently. I have an Acer Aspire One ZG5 with Ubuntu 10.04 2.6.32-22 generic. My touchpad is completely dead for all users. Unlike others it does neither temporarily work at the login screen, nor randomly, nor for a limited period. I tried Fn-F7, gconf-editor (Touchpad is enabled), mouse settings menu, checked outputs from dmesg | grep Touch, xinput list-props "SynPS/2 Synaptics TouchPad" and cat /proc/bus/
Then I booted from a USB start-up stick with Ubuntu 9.10, with the expectance that touchpad would work again which would allow me to find the differences in settings. Guess what: it did not. I did the same listings and settings check, compared with the previous investigations. Again found nothing weird. Unless the problem was also present in the ubuntu-

Giorgi Maghlakelidze [DrAcid]:
Solution 93 allowed me to use my touchpad again, but it didn't really fixed the whole problem, because when I use on/off button for the touch pad, my touchpad mouse crashes, external usb mouse stops clicking, and keyboard starts to malfunction. This is triggered when I press on/off button for HP laptop touch-pad. If to be honest, I'm sure that this solution:
gconftool-2 --set --type boolean /desktop/
is not the cause of the problem. There is something deeper, maybe related to the new kernel, because on ubuntu 10.04 final release first install everything worked fine as far as i remember. After few kernel and other updates this bug kicked in.

Dear all,
One-and-a-half weeks after my initial reaction (#95) on this bug I can report it solved in my particular case. A couple of weeks ago I tried to flash the BIOS on my Acer Aspire One 150. I followed the official Acer instructions by placing the new BIOS files on a USB stick and then hold three particular keys during power-up. After three attempts the version number still showed the old version. It must have been around that time that the touchpad stopped working too. Today I succesfully updated the BIOS by means of bootable USB stick (unetbootin, FreeDOS). And to my big surprise: the touchpad worked!

Here is what fixed it for me (HP Pavilion DV6730ec):
First of all, open a terminal. Press Alt+F1 to open the applications menu and choose the Terminal application from the accessories or use an external mouse to so.
To bring your touchpad back to life, enter the following command:
Code:

This dissociates the key to lock your touchpad from gnome-settings-

Hope this helps. I recommend rebooting after this procedure and check if this really fixed it for good. I noticed that the error only occurs only once after a reboot.

I do not now if I have the same problem, but I found very simple solution for mine:
When I switch touchpad off with "Disable" button (physical button near touchpad) and reboot, my touchpad starts working again.
The problem reappear, if I reboot with the touchpad switched off again.
So it looks like either Gnome or Synaptics Driver dose not save ON/OFF state when you reboot, and another thing (Gnome or Synaptics Driver) does. And after reboot their ON/OFF states are inconsistent.
I use Acer Aspire 5740 and Ubuntu 10.4.

Hi there all,
I am a Linux newbie. I recalled that I had had similar problem with Karmic about 4 months ago and I had fixed it then. After some recalling, I got it and here it is:
I went to the System -> Administration - > Windows menu and went to the Windows Preferences tab.
There for the "Movement Key" there is a radio button selection of "Super Key" or ALT" key. BOTH radio buttons had somehow become enabled, I do not know how this happened, but I suspect it is because I installed SUGAR. However, when I selected just one option there, the Touch Pad began to work immediately.
I hope this is of help to someone.

I would like to add that I DONT have a trackpad or touchpad installed, and use an MS Wireless Multimedia Keyboard V1.0A (WUR0335).. This issue presented itself and the keyboard would just stop working. The menus in 10.04 would highlight (i.e Applications, Places and System) but no dropdown would occur. I disabled any desktop effects to no avail.
At first, I kept hitting the power button on the machine to switch off and on, as the menus would not respond, however, as un-scientific as it is, if i pressed my hands on as many keys as possible, I was given an Ubuntu Notification then my keyboard stopped working.
The notification looked like a trackpad, so I looked in the notification folder, found the icon, and found what normally uses it for notifications (BTW - There was no record of the notification in the log!)
From there, it led to this bug, and to this fix :
gconftool-2 --type string --set /apps/gnome_
~Which runs at every login. I know, elegant, eh?
This is a fresh 10.04 install.. One thing I did notice tho, is bug 192508. That bug could be related to Remote Desktop.. Is there a possibility this could also be? Does anyone have RD Enabled?

Giorgi Maghlakelidze, Thank you so much!!! Post #93 fixed the problem for me (on Lucid Lynx 10.04, HP Pavilion Laptop). That bug affected me for ages.
Anyone else who has this problem, paste this into your terminal:
gconftool-2 --set --type boolean /desktop/
Thanks again.

@Will Miller & oktapod:
No problem! ;)
Glad U guys resolved the issue!
For those on whose machines the bug "returns" occasionally(it did on mine!) :
I have added a keyboard shortcut via System-
gconftool-2 --set --type boolean /desktop/
It just saves time U know... ;)
Oh, BTW, I am on Maverick Meerkat x32 Beta. NO TRACE OF THE PROBLEM...

I have been on 10.10 for a few days and it just started doing this on my HP Pavilion DV6103NR. It started after I used the mousepad lockout button on the mousepad.

Post # 9 worked for me, I lost touchpad and keypad after updates, Broadcom started working but I could'nt do anything with it!!
I used USB mouse and keyboard to open terminal to run:
sudo apt-get install gpointing-
After reboot the Linksys wireless card, touchpad, AND keyboard were all working perfectly!
Thanks!

I just upgraded my Lenovo Thinkpad T410 to 11.04 Natty and hit this issue. The solution that worked for me seems a bit simpler than some of the ones offered earlier so hopefully this will help someone.
Hit Alt-F2
Type gconf-editor and hit return
Browse to desktop/
Look for your touchpad - mine looked like "SybPS@47@2..."
Uncheck the "disable while other device exists" option
Bingo!
Presumably the problem was that Thinkpads have two built-in pointing devices. While the solution turned out to be simple, it took me a good hour to figure it out and the earlier comments in this thread helped me to start looking in the right place. Thanks.

IMPORTANT - this contains steps to reproduce the problem.
Comment #103 above has the solution - but it's slightly more subtle than this.
I can easily reproduce the problem on my Acer netbook which has a dedicated keypress (Fn F7) to toggle the touchpad on or off. I'm running Ubuntu 10.04.2 LTS Netbook.
It seems like the touchpad is enabled in two different places. The one we know about is at /desktop/
Normally when you hit Fn F7 the touchpad toggles reliably between the enabled and disabled states.
But it's like two electrical switches in series. Provided they both remain in step it works. But if there's ever a glitch that causes one switch to be off while the other is on, there's no easy way to correct it. Hitting Fn F7 will just reverse the existing state. But with one switch on and the other off the touchpad never gets enabled.
Steps to reproduce.
(1) Use gconftool-2 to monitor the state of the relevant gconf key using the command below.
gconftool-2 -g /desktop/
Press Fn F7 repeatedly and each time check the results with gconftool-2. As expected, you can see the key toggle from true to false and back again. At the same check that the touchpad is being enabled and disabled correctly. This is the normal behaviour.
(2) Finish up with the key value set to false. Now use gconftool-2 to change the key to true using the command below.
gconftool-2 --type bool --set /desktop/
Note that this sets the two flags out of step with each other.
After this you can keep on hitting FnF7 and see the gconf key change from true to false. But whatever you do you can't get the touchpad to work. Whenever gconf thinks the keypad is enabled the other flag thinks it is disabled and vice versa.
To solve this, the software needs to link the two flags together so they can never have different values.

This also affects 11.04 and 11.10, so maybe its better to remove the 10.04 from the subject, as this is still a current and annoying bug

on 11.10 the "disable touchpad while typing" seems to activate again this problem... some times disabling and re-enabling the touchpad several times make the touchpad return back to life... but doesnt work always.
also, on 11.10, disabled the touchpad and re-enable one will not work, i need to do it twice to really re-enable the touchpad.
it looks like there is yet another apps trying to play with the touchpad and confusing even more this

On a Toshiba Protege M700, I did not have the issue with 11.04 amd64. After the upgrade to 11.10, my touchpad stops working shortly after login. Performed fresh install of 11.10 amd64 and issue persisted.
Unchecking "disable touchpad while typing", as suggested in this bug, keeps my touchpad functional.

Just installed 11.10. My Synaptics PS/2 mouse was working before (11.04) but post upgrade it stopped working right after login.
I did two things to (seemingly) fix it.
(1) sudo apt-get install --reinstall xserver-
(2) gconftool-2 --type bool --set /desktop/
After one reboot it seems to be working post login.

But....
It is clear the button to 'disable' my touchpad and 'disable while typing' puts some set of variables in a state where my touchpad does not work.
going to try:
removing 'psmouse.ko' > add it back
xinput list
gconftool-2 --type bool --set /desktop/
If that doesn't work, I might try reinstall w/ apt-get.

It seems like these two commands together get them back in sync:
synclient TouchpadOff=0
gconftool-2 --set --type boolean /desktop/
Either one of them will make my touch pad start working, but both together seems to fix the problem.

this problem exists on Linux Mint 12 and 13, but for some reason is not affecting me on Ubuntu 12.04...
unchecking "disable touchpad while typing" fixes the issue. in order to avoid accidental clicks, you must also unceck "enable mouse clicks with touchpad" and use the purpose-built buttons only :) (are they really that inconvenient?)
