[Bug 1992235] [NEW] Screen freeze

[Launchpad Bug Tracker]

Updated to 22.10 beta last week.

When I return after screensaver activation, the display freezes.
Sometimes the greeter fades in a little bit, sometimes it is just the
background image. Every time, I can move the mouse and the cursor
changes when hovering over the password box (or where it would have
been). I can type my password and the session unlocks. I know this
because the greeter process is gone, and the mouse cursor now changes as
if it were my desktop (input boxes, buttons, etc) but the display still
has never updated.

This has happened about 5 times now, but reproducing it could be hard
because it only seems to happen after an idle period when the screen
locks itself. Manually locking/unlocking the screen works fine.
Switching off the monitors with "xset dpms force off" also doesn't seem
to trigger it.

There doesn't appear to be anything useful in the log files, but I think
apport has attached them anyway.

Happy to do any debugging necessary.
