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.

I can confirm that since upgrading to beta 2 my touchpad on an HP dv2054ea stopped working. If I uninstall the xserver-xorg-input-synaptics driver it then works, although in a slightly erratic fashion.

Yup, this is exactly my problem either. Acer Aspire one ZG5...
I hope this will be fixed soon, or at least a workaround from anyone... I use the touchpad more often then the mouse (I actually got used to that thing! :O ). I'm glad I've found people with the same problems, that means it should be fixed one of these days :)

Jarige (jarikvh) wrote :

Isn't this a bug in xserver-xorg-input-synaptics since it is gone when removing this package?

Jarige (jarikvh) wrote :

I did some testing; and previous versions of xserver-xorg-input-synaptics don't work. I thought it would work as a workaround, but it didn't. The 1.2.2-1ubuntu1 version had the same problem (apparently, the current version and 1.2.2-1ubuntu1 were released 41 seconds after oneother) and 1.2.0-3ubuntu2 acted as if the drivers weren't installed. The touchpad was very weird acting, and I could not scroll etc.
I tried 1.1.2-1ubuntu7 (the current version in Karmic) but that one didn't install because of some package conflict.

I hope that anyone finds this information useful in some strange way :) I just wanted a workaround and thought a previous version might fix it.
So I'm still having this problem... :(

Jarige (jarikvh) wrote :

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...

Jarige (jarikvh) wrote :

Is there any way of notifying this bug report to the xserver-xorg-input-synaptics developers? If they don't know this bug, they won't be fixing this bug. I don't know how that works though. I think it has something to do with the 'also affects project' button, but I couldn't find that package name anywhere.

I changed the "Affects" column at the top of the page, changing it from "hal" to "xserver-xorg-inputs-synaptics". Maybe this can be helpful to the developers of such package.

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.

After getting frustrated and deleting all gnome configurations with:

rm -rf .gnome .gnome2 .gconf .gconfd .metacity

obviously this is a bit of a pain, but better than the touchpad not working. I will post another comment if the problem happens again.

Jarige (jarikvh) wrote :

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.

Jarige (jarikvh) wrote :

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 ~/

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.

Ben Munro (benjamin-munro) wrote :

The above fix works for me, but leaves me with a non-accelerating pointer and unable to scroll with the touchpad.

I found another fix that works better.:

rm -rf /home/ben/.gconf/desktop/gnome/peripherals/touchpad

You need to kill the session (killall gnome-session) and log in again after you do this. The bug keeps re-occurring and needs to be fixed every time.

This is on a Hewlett Packard dv6 2113tx.

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.

Warm Regards

Had same problem on acer aspire laptop.

touchpad worked, then stopped working for my user only. When logging in with my son's user, the touchpad worked fine. So went with the deleting the .gnome2, gconf etc etc solution as it seemed to be user specific and not system specific (the modprobe solution).

Touchpad now works fine, but all other settings gone too. Bit of a pain, but not too hard to put right.

Nick Twigg (nick-nick-web) wrote :

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_settings_daemon/keybindings/touchpad ""

~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?



I'm running a Acer Aspire One 110 with Lucid (10.04), with all updates current.

I've had a non-functional touchpad since I installed Ubuntu on the AAO (v.8.xx), and nothing I've done has resuscitated it - until I read comment #93, which has worked like a charm.

Many thanks.

Tried everything here, nothing works for me so far.
My laptop is: Blue, Model #626
Problem: Touchpad doesn't work at all. cursor not moving, no respond from left and right clicks. it is also not recognized on the xinput --list command.

i've got to thinking, mine has a manual on/off switch for my touchpad. could it be because linux does not recognize this switch that's why it is not working at all?

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/gnome/peripherals key
Look for your touchpad - mine looked like "SybPS@47@2..."
Uncheck the "disable while other device exists" option


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.

Bob B (tenbob1) wrote :

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/gnome/peripherals/touchpad/touchpad_enabled. The other is elsewhere, presumably in the Synaptics device driver. Both persist over a reboot.

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/gnome/peripherals/touchpad/touchpad_enabled

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/gnome/peripherals/touchpad/touchpad_enabled true
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.
