Public bug reported:
About a week and a half ago I would lose rendering of the desktop
randomly while under a Wayland session. I would have the last displayed
images on my monitor, mouse movement worked, video and audio still
workedd, but visual feedback was lost when clicking on items in the
browser or last app opened. Spacebar would work fine to pause a video,
or media keys to stop the music player.
I've been trying to hunt down the reason until I realised that I might
be running under Wayland instead of Xorg. I changed the configuration
option in /etc/gdm3/custom.conf to disable Wayland and enabled debugging
and restarted.
I was away from my desk earlier when I logged, in a few minutes later
the screen went black, as if it went into power saving mode. Unlike the
Wayland sessions I wasn't able to get to any TTY's.
Upon restarting I noticed the following, which wasn't present in the
previous journal under Wayland (see attached - to large for description
field).
At this point, this seems to be occurring randomly. I'm happy to help
with debugging if need be.
