Re: Troubles with X1 Carbon 2018 (X1C6) TouchPad and TrackPoint under Linux

I have Ubuntu 18.04.1 (4.15.0-39-generic) and 1XC6. I updated bios (1.34)

$ fwupdmgr get-devices
$ fwupdmgr get-updates
$ fwupdmgr update

Touchpad is working, but 'tap-to-click' sometimes doesn't work. After few minutes it is restore. Trackpad buttons do not work after first sleep/wake-up.

Touchpad problems with BIOS 1.34 still, but not with Ubuntu Budgie!

Just got my X1C today and ran into this problem with Ubuntu 18.04: the touchpad would respond for ~1 second every 10 or 20. In 18.10, it would respond a bit more often, or even work for minutes on end, until I'd suspend.

 

In the BIOS, I had enabled the Linux options for sleep and Thunderbolt. I've updated the system firmware to 1.34.

 

As the OP mentioned, disabling the trackpoint in the BIOS did lead to the touchpad working as intended, including two-finger scrolling (but it did, however, also disable the physical buttons above the touchpad).

 

Something interesting though, is that the touchpad and trakpoint worked fine in Ubuntu Budgie 18.04.1 (after being frozen for ~30 seconds after boot). Maybe someone more knowledgeable can take a look and see how Budgie solves the problem.  If you do, please post on the corresponding Launchpad issue as well.
