Touchpad stopped working on ThinkPad x220

I'm more familiar with KDE than the default Ubuntu interface, but the first thing I'd check would be the current settings in System Settings > Mouse & Touchpad - and if enabled try disabling, applying and re-enabling. It's possible that one of the updates has reset the configuration and/or installed an updated module for the particular touchpad (Synaptics?).

Also can you give the full output of:

lsmod; lsb_release -a; uname -a

Thanks

@cputtick I've tried most of that, will do again.

Sorry, it posted twice...

No worries. If you run:

sudo rmmod psmouse
sudo modprobe psmouse proto=bare

Does the touchpad work?

Yes, that made it work. Thanks!

The touchpad tab in the Mouse and Touchpad setting has disappeared, however, and I'd like to adjust the speed and re-enable two-finger scrolling.

Arggh, that double posting again (trackpad reset also enabled tapping-as-left-button, another setting I always turn off).

This will not be persistant, we need to make a file to make the settings stick.

run:

echo "options psmouse proto=bare" | sudo tee /etc/modprobe.d/psmousefix.conf > /dev/null

Now when the module is loaded, the option will be used by default.

I'll give it a try, thanks...

@actionparsnip

OK, I ran that command and now the touchpad is running when I log in. However, as noted above, I'd really like to recover the ability to adjust the settings -- as far as Synaptiks and the Mouse and Touchpad settings are concerned, there's no touchpad. Any way to get that back?

Very much appreciate your troubleshooting this...

That I am not sure of, are there any bugs reported?

Not that I know of. So I have to ask, how do I disable the touchpad but keep the mouse? I'm grateful for your help, but the current setup is actually worse for me than just using the Touchpoint.

Hi ,

can you give the results of

synclient

Thanks

Hi ,

try

synclient HorizTwoFingerScroll = 0 and see if Vert two fingers scroll working

synclient MaxSpeed = 2.00 to increase the speed

synclient TapButton1 = 1
or
synclient TapButton2 = 1
or
synclient TapButton3 = 1
and see the behavior of tapping.

I think you can figure it out . If you want something to make it permanent , then add it to startup application as command. At command box write the command : eg , synclient TapButton1 = 1

If you want a GUI version of synclient install gsynaptics

sudo apt-get install gsynaptics

call the program from terminal with this command
gpointing-device-settings

configure your touchpad.

Thanks

Getting errors with all of these, e.g.

synclient HorizTwoFingerScroll = 0
Invalid command: HorizTwoFingerScroll
Unknown parameter
Invalid command: 0

and,when running

gpointing-device-settings

An X error occurred. The error was BadAtom (invalid Atom parameter).

Be careful with the syntax :
synclient HorizTwoFingerScroll=0
This is correct (without spaces between ll = 0)
The output must be nothing. You can check if value changed correctly
with command :
synclient
and see the results.

This is normal . I expect a window to open and let you configure the
touchpad settings (through a GUI.)
I have the same error , but window opens and I can configure my touchpad
settings.

Thanks

I've tried all of this but unfortunately it's still not affecting the settings.

Hooray -- over on Google+, some folks had a bunch of suggestions, one of which worked: Using dconf-editor, which got the touchpad working again. I'm not sure why this worked, but I'm happy enough!
