Comment 4 for bug 1876991

I have a similar problem in Ubuntu 20.04
Dell Precision 5510.

The touchpad randomly ignores 'clicks'. (both mechanical and touch clicks).

I get similar results from xinput --list:

$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=16 [slave pointer (2)]
⎜ ↳ DLL06E5:01 06CB:7A13 Mouse id=11 [slave pointer (2)]
⎜ ↳ DLL06E5:01 06CB:7A13 Touchpad id=12 [slave pointer (2)]

AND, have similar errors in the boot and shutdown log files:

psmouse serio1: Failed to enable mouse on isa0060/serio1
psmouse serio1: Failed to enable mouse on isa0060/serio1
psmouse serio1: Failed to deactivate mouse on isa0060/serio1: -5
