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.
