Screenshot - screen configuration
SUMMARY
When returning from "suspend", the monitors do not turn on or return with low
resolution (640x480). Wayland does not allow changing resolution (attachment).
I have two HP V206hz monitors that have a maximum resolution of 1600x900x60hz
and are connected to a Radeon RX 6600 via cable (displayport > DVI).
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.

***
STEPS TO REPRODUCE
1. Manually suspend the computer.
2. Wait for the suspension process to finish (front panel LED flashes).
3. Press any key to wake up the computer.
OBSERVED RESULT
Screens go black after manual suspend.
One of the screens returns with 640x480 resolution after returning from
automatic suspend (when automatic splint shutdown is not active).
If the screen turns off automatically (before automatic suspend) the monitor
video returns with adequate resolution (1600x900)
EXPECTED RESULT
Screens turn on after computer resumes from sleep.
