On Ubuntu 20.04, my Touchpad is having weird bugs that start at random moments that I couldn't link to any special activity. It seems to just start randomly.

Here are the different effects that I can have:

  • when I move the mouse, after I stop moving my finger, the cursor starts slowly moving a few pixels more which makes it very hard to be precise to click on buttons or links
  • The scroll with 2 fingers stops working (I checked and the option is still enabled in Ubuntu's parameters)
  • The mouse starts moving incredibly fast

Those effects stops after a while for no apparent reason.

Also, despite having separated sliders for TouchPad speed and Mouse speed, only the Mouse speed is taken into account.

Update the kernel, get all the latest modules exist at the moment. If there is no module for your device, it will try to be generated. Reserve device and vendor keys for aliases in the blacklist from the output of the dmesg command.
