Bug Description
It was working perfectly on 18.04 with 5.3 kernel but after upgrade to 20.04 it's becoming disabled because there is a "mouse" attached which is the same touchpad detected incorrectly, xinput --list showing both
⎜ ↳ MSFT0001:00 06CB:7E7E Mouse id=11 [slave pointer (2)]
⎜ ↳ MSFT0001:00 06CB:7E7E Touchpad id=12 [slave pointer (2)]
The first line was definitely not present before, I know it because I use it when in openbox session.
There is also a number of questions on AskUbuntu that look like results of the same problem at first glance:

and two global search results for the same touchpad model ("MSFT0001:00 06CB:7E7E Mouse") that show the same problem in unrelated contexts:

I also have these errors in kernel log, may be related, weren't present previously:
psmouse serio1: Failed to deactivate mouse on isa0060/serio1: -5
psmouse serio1: Failed to enable mouse on isa0060/serio1

Changed in xserver-xorg-input-synaptics (Ubuntu): | |
importance: | Undecided → Low |
After removing xserver- xorg-input- libinput third input device appears, a 'PS/2 Generic Mouse' and both mice become evdev devices so it doesn't look like a libinput problem.
