Bug Description
Ever since upgrading to focal from eoan, my trackpad stops tracking motion after a while. I'm just mousin' along switching apps and tabs; selecting, cutting, pasting; doing all that usual stuff and suddenly the cursor doesn't move. Tapping on the touchpad generates the expected left- or right-click events. My external mouse still works.
This has happened with kernel 5.4.0-28 and 5.4.0-29; 5.3.0-46 was working just fine.
$ lsb_release -rd
Description: Ubuntu 20.04 LTS
Release: 20.04
$ uname -a
Linux thorium 5.4.0-29-generic #33-Ubuntu SMP Wed Apr 29 14:32:27 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
Messing around with the touchpad settings doesn't restore the touchpad to operation, though it can enable/disable the mouse clicks.
Suspend and resume doesn't restore the touchpad.
A reboot fixes the touchpad.
So now, I shall grudgingly reboot. :(
Interestingly, logging in and out again makes the trackpad work, no reboot needed.
