Public bug reported:
I have 3 monitors, but since very recently (yesterday or so), only 1 of
them seems to be detected.
In the Settings app, under "Screen Display", I used to have a place
where I can move my monitors relatively to each other, and adjust each
of their settings. Now, I no longer have the monitor drag-and-drop zone,
I only have one detected "Unknown display", fixed at 1920x1080 77.00 Hz
(physically, it's a 1920x1080 144Hz) and I cannot change any setting
except orientation, scaling, and fractional scaling.
The bug started happening just when the kernel was auto-updated to
5.15.0-60-generic from 5.15.0-58-generic. `uname -a` reports: `Linux
user-desktop 5.15.0-60-generic #66-Ubuntu SMP Fri Jan 20 14:29:49 UTC
2023 x86_64 x86_64 x86_64 GNU/Linux`. When I reboot with
5.15.0-58-generic, all of my 3 displays are detected and working fine.
I also noticed the same problem happened when I installed
5.15.0-58-lowlatency.
