Mouse pointer freeze after some time on thinkpad t14

Hello everyone,

Since a couple of updates of manjaro testing, I have this strange problem.
My trackpad works perfectly but after some time the mouse pointer freezes a little bit and then resumes.

I checked dmesg -T and it says:

I am on kernel

Linux futura 6.13.1-2-MANJARO #1 SMP PREEMPT_DYNAMIC Mon, 03 Feb 2025 16:27:16 +0000 x86_64 GNU/Linux

After some of these freeze/resume the mouse just gets stuck on the screen and I can’t move it. So I have to reboot the whole machine, logout and login looks like it does not work.

I googled a lot, and some people mention that installing extra/xf86-input-synaptics might help, but pacman says that this driver is under maintenance.
Also there’s a mention to use the pci=nocrs paramater in grub.
I haven’t yet tried that parameter though.

Does someone has experienced a similar (freeze) behavior?

Please let me know if I need to post more logs.

Thank you in advance!

I am guessing this could be caused by a power event of some kind.

You tagged with Plasma - is this Wayland or Xorg.

If it is Wayland using the synaptics package will likely make no difference as Wayland uses libinput for keyboard/touchpad/trackpad/mouse communication.

If you are using Xorg - even though the synaptics driver is in maintenace mode - it does not mean it is not working - but it will - eventually - be superseeded by libinput.

I am using Wayland. thanks for the reply.

If it freezes, try sudo modprobe -r psmouse && sudo modprobe -a psmouse in a Terminal. I have to do this sometimes, usually following the first sleep/resume cycle following a reboot but occasionally it just happens at random.

If you have Yakuake enabled, you can press F12 to access the drop-down Terminal.

As for the brief “freezes” this could just be down to system load.

I noticed that, when the pointer freezes, if I close, wait for suspend, and reopen the laptop lid, the mouse pointer resumes its normal operations.

Small update: I traced down the kernel driver and I created a simple shell script that does:

\cat bin/touch-reset.sh                                                                                 ✔ 
#/bin/bash

sudo rmmod i2c_hid_acpi
sudo modprobe i2c_hid_acpi

Still a workaround, but it works. I am still not sure if it’s an hardware problem or a software one

Another update:

Since some kernel versions my trackpad seems to behave correctly. No freezes!
Now I am not sure if it is a hardware problem or a software one, however my touch-reset.sh luckily became obsolete! :wink:

Necro-commenting in the hope that someone else might find it useful!

And closing the thread just to prevent someone from going #MeToo six months from now. :stuck_out_tongue:
