Thinkpad T14 Touchpad Synaptics problems on Kubuntu

2021-06-07, 9:57 AM

This is happening on other models, but on this specific model Thinkpad T14 with an AMD Ryzen CPU , that is also listed on lenovos website "linux for personal systems" to work with 20.04, has touchpad problems.

When the system boots up, the touchpad does not load in correctly, you are able to use the trackpoint, that's in the middle of the keyboard, but the touchpad usually fails to work and requires the computer to restart, sometimes several times. It varies alot and is very random.

Very frustrating problem, we've looked around for fixes, something about adding quiet.splash into the boot entry, we have tried updating the kernel yet it fails to fix the problem.

Read something about blacklist and drivers within boot entries? Would love some help anyways on how we could go about this and if anyone else has encountered this problem on the specific laptop or touchpad.

The laptop is using a Synaptics touchpad, here's some information from cat /proc/bus/input/devices:


I: Bus=0011 Vendor=0002 Product=0007 Version=01a1 N: Name="SynPS/2 Synaptics TouchPad" P: Phys=isa0060/serio1/input0 S: Sysfs=/devices/platform/i8042/serio1/input/input7 U: Uniq= H: Handlers=mouse0 event6  B: PROP=5 B: EV=b B: KEY=e520 10000 0 0 0 0 B: ABS=660800011000003

We're using Kubuntu 20.04 with KDE Plasma. We've tried kernel 5.12 without any luck.

 

Let us know if there's anything we could try, thanks in advance!

I suppose you don't have any ideas on what to do about this issue?

Thanks

What is the BIOS version on this machine, if it is 1.30 please either upgrade to a later version or downgrade to 1.29 and retest.

I seem to be having a similar issue with my Lenovo T14 AMD G1 (20UDCTO1WW). Installed OS is Ubuntu Mate 20.04. Seems to have the same issue even with a Ubuntu Desktop Live USB boot media.

Trackpad refuses to work even in the BIOS config GUI. Running BIOS version 1.32.

Will try downgrading to 1.29 and retest as well.

I used fwupd and reinstalled the last BIOS version it had listed (1.25) since that seemed like the quickest easiest way to get to an older BIOS version installed.

 

Trackpad now works as expected.

 

Seems 1.32 at least might introduce an un-fun bug. Was running 1.29 until a few days ago and skipped 1.30.

 

As I tend to have the laptop docked I didn't catch this issue right away.
