Bug ID: 457755
Summary: Plasmashell problems after changing the HDMI output
and KDE does not recognize the new display
Product: plasmashell
Version: 5.18.8
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: myndstr...@protonmail.ch
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See

***
When I started a computer from standby after connecting the HDMI cable to
another display, it didn't recognize the new monitor and still had the previous
monitor set. There should be a rescan/refresh button in the Display system
settings. It recognized the display after moving the HDMI cable back out and in
again.
Furthermore, whenever I connect to another monitor the plasmashell seems to
crash (I have to run killall plasmashell and kstart5 plasmashell, I don't know
if it crashes or crashes all the time but the background image is black and the
bottom panel is missing) and the konsole windows freeze. Could look into some
logs if this is still a problem.
I don't know if this is already fixed or if there already is an issue for that.
Furthermore, when connecting the HDMI another monitor it should automatically
change the resolution to the highest available for that monitor, not keep the
current resolution which can result in no image at the new monitor until the
resolution is lowered for all displays in the system settings
STEPS TO REPRODUCE
1. Connect HDMI to another monitor with a different resolution (with or without
standby)
2. Connect HDMI back to the previous monitor
OBSERVED RESULT
Plasmashell problems after changing the HDMI output
EXPECTED RESULT
Changing the HDMI output should not result in any plasmashell problems and the
output should work plug&play so any needed system settings are configured
automatically.
