[Hardware] X220 Touchpad on Debian 11

#1 Post by m3m3 »

Hi at all. Recently i've bought a Thinkpad X220 on which i've installed Debian 11. All system run smooth except for touchpad(clickpad) that run lazy and jumpy. Reading on the web seems that could be a firmware problem, 8.1 version is buggy compared to 8.0. I've tried to create a new file on hwdb.d folder but doesn't work. Thanks for all...have a good day.

Back when I used a T420, I had the same problem and found that switching from libinput to the old synaptic drivers worked better. However, I'm not sure whether those 2 models have the same touchpad. They are from the same generation of Thinkpads though.

The way I did it was to install the Synaptics driver

Code: Select all

apt install xserver-xorg-input-synaptics
and then remove the libinput driver:

Code: Select all

apt remove --purge xserver-xorg-input-libinput
If it doesn't work, just reverse the process.

Here are some additional hints for configuring the Synaptics driver:

hi...thank for reply... I've t420 also and in this machine the touchpad work perfectly. I'm not sure that is the same touchpad, because the x220 have integrated button (clickpad). I've already tried to install xserver-xorg-input-synaptics but don't work. If i try to remove xserver-xorg-input-libinput package i broke task-desktop dependecies.
