Lenovo P50 Trackpoint/Trackpad quit working after latest Leap 15.1 software update

English Hardware

I have a Lenovo Thinkpad P50 running Leap 15.1 and KDE5. Yesterday a fairly large software update was pushed out to my Thinkpad. The update included a Kernel update.

When I booted my Thinkpad today, the Trackpoint and Trackpad were not working. The cursor is visible in the center of my screen, but I cannot move the cursor.

I am able to control the cursor with a USB Mouse and when I dual-boot to Windows 10, the Trackpoint and Trackpad work normally. It appears to be a driver issue with the Kernel update.

Here is the current info on the Kernel:

P50:/home/gjjohnson/.local/share # locate xorg-session.log
P50:/home/gjjohnson/.local/share # cd /
P50:/ # locate xorg-session.log
P50:/ # modprobe -r psmouse; sleep 2; modprobe psmouse
modprobe: FATAL: Module psmouse is builtin.
P50:/ # uname -r

P50:/ # uname -a

Let me know if there is a fix for this problem or if you need additional information to find the root cause.

Thanks!

Can you boot to an older kernel (advanced settings in the grub menu) and check behaviour there?

Not that guy, but I have the same problem on my Thinkpad X240. Booting older kernel fixed it for now.

Yes, falling back to the previous kernel version works.

There must be a problem with the newest kernel – I can boot the previous version until this is patched in the next kernel release.

Can I be notified when this is resolved?

Thanks!

You’ll need to check if a bug report exists for it, and you can create/subscribe to a bug report (your same credentials as forum).

Either of these could apply:

Yes, this one. And the repaired kernel mentioned there solves the issue.

The latest Kernel push has resolved this issue:

P50:~ # uname -r
4.12.14-lp151.28.32-default

I rebooted after the Kernel install and now my Trackpoint / Trackpad are working again.

Thanks, everybody!
