Manjaro KDE: Touchpad hangs/freezes up frequently on Lenovo X1 Carbon 6th Gen

Hello all!

After installing Manjaro for the first time on my Lenovo X1 Carbon 6th Gen, I came across some strange behavior. Almost every time I resume from a suspend the trackpad gets into a state where it will move the cursor a little bit then freeze up for another 10-30 seconds and move a little and freeze up, etc. I also had this problem on Deepin (not Manjaro Deepin), and a search online for a fix to this problem did not come up fruitful for either distro. The cursor moves fine when I use a mouse, and the trackpad works perfectly in Windows. The trackpad also works fine right after a hard reboot.

Things that I have tried:

  • Disabling the trackpoint in the BIOS
  • Using both the libinput drivers and synaptic ones
  • Messing around with palm detection and trackpad settings ingeneral
  • Restarting the psmouse module after a suspend
  • Changing the sleep optimization option in BIOS to linux

I’m not very linux savvy so I didn’t go much further than what was in my comfort zone.

Any and all help will be appreciated!

Have you seen this?

Create a script say tpad.sh containing:

#!/bin/bash 

echo -n "none" | sudo tee /sys/bus/serio/devices/serio1/drvp 2
sleep 2
echo -n "reconnect" | sudo tee /sys/bus/serio/devices/serio1/drvctl

Make it executable:

chmod +x tpad.sh

Run it with sudo. If that works, it can be put into a unit to run on resume from suspend.

Here is lots of examples of what you may want to use for a service unit.

Okay, so I don’t know what I did (I tried multiple things that could have solved it) but for some reason it just started working. Thanks for the help y’all are great!
