Touchpad hypersensitive after suspend (workaround)

If you ever experience an issue where the touchpad becomes hypersensitive (motion) and multitouch gestures fail after resuming from suspend – happens to me occasionally – do this

sudo rmmod hid_multitouch
sudo modprobe hid_multitouch

I don’t have any clue why this kind of thing would happen, but just leaving the workaround here in case someone Googles for it!

I’m running Ubuntu 21.10 with Cinnamon.


Another option is to disable PS/2 emulation in the BIOS.

If you don’t want to do either of those, I found that just not touching the touchpad until the login screen appears again helps.


Thank you! I’ll try that

I can confirm this seems to work for me after a several reboots/suspend-resume.
