Title:
Touchpad started appearing both as a touchpad and as a mouse input
devices after upgrade to 20.04
Status in xserver-xorg-input-synaptics package in Ubuntu:
Confirmed
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:
https://askubuntu.com/q/1231873/20275
https://askubuntu.com/q/1235067/20275
https://askubuntu.com/q/1234975/20275
and two global search results for the same touchpad model ("MSFT0001:00
06CB:7E7E Mouse") that show the same problem in unrelated contexts:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=953405
https://bbs.archlinux.org/viewtopic.php?id=240723
I also have these errors in kernel log, may be related, weren't present
previously:
