Public bug reported:
After installing 22.10 beta, the gdm3 does not start properly. This
happens only if in /etc/gdm3/custom.conf :
[daemon]
# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=false
(...)
The line with WaylandEnable is commented out or set explicitly to
WaylandEnable=true.
Then the system boots into the state when the screen is black, there is
underscore "_" present in top left corner, one can ssh into the system, but
keyboard input is ignored. With WaylandEnable=false the system is fully
functional. Before the update, with WaylandEnable=true the have been no such
problems.
I will attach any logs upon request. Below those that I thought of on
myself:
Description: Ubuntu Kinetic Kudu (development branch)
Release: 22.10
gdm3:
Installed: 42.0-1ubuntu7
Candidate: 42.0-1ubuntu7
Version table:
*** 42.0-1ubuntu7 500
500 http://archive.ubuntu.com/ubuntu kinetic/main amd64 Packages
100 /var/lib/dpkg/status
Note that the system logs have been created as follows:
1) I booted the machine with WaylandEnable=true,
2) I sshd into the machine, changed WaylandEnable to false, and restart gdm3
so the last few entries will likely describe the proper "x11" launch of the
gdm3.
cat /var/log/syslog | grep -i gdm3
is attached as gdm.log
