Bug ID: 500966
Summary: Display Resolution on secondary display resets to
640x480 - intermittent
Classification: Applications
Product: systemsettings
Version: 6.3.2
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org

hwinfo --display --monitor
SUMMARY
I have 2 displays, the secondary which is rotated 90 degrees will often return
from "sleep" or some other power state at the minimum possible resolution, and
sometimes simply will not wake at all. I can manually change the resolution
back, or reboot the PC to fix it.
It does not happen every time.
I have not tried simply restarting sddm (hasn't crossed my mind until just now)
This only began several days ago with an update. I am fairly religious with
updating, so it was almost certainly an update released within the past 2-3
days.
Second possibly related issue:
When the displays dim automatically, sometimes the primary display will not
return to normal brightness until I either drag the brightness slider (which is
still at the normal setting) at which point normal brightness will resume in
about half a second, or use the hardware button on the display itself which
(consistently) will have been reduced to 10.
Secondary display does not exhibit this behavior.
I have not created a second issue as of yet.
STEPS TO REPRODUCE
1. Let display(s) sleep
*or*
2. Let PC sleep
*or*
3. Let display(s) dim
OBSERVED RESULT
Displays will not always return to the previous settings as configured in the
display section of the settings UI.
EXPECTED RESULT
Displays should return to the previous settings.
