Bug ID: 402370
Summary: Multi monitor config lost while returning from standby
Product: KScreen
Version: 5.14.4
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common
Assignee: se...@kde.org
Reporter: benjamindai...@gmail.com
Target Milestone: ---
SUMMARY
I'm running the latest release on Manjaro with dual screens set up. The issue
I'm having is that when the displays go to standby, then wake back up, Plasma
doesn't seem to remember my config. My DVI display wakes up first, Plasma
detects it, snaps into single display config, then the HDMI display wakes up,
Plasma detects it, and then snaps back into my configured display layout.
Plasma should just remember the layout, in fact, as the computer is still
running and the displays haven't actually been disconnected, there's really no
need for Plasma to re-detect displays at all.
STEPS TO REPRODUCE
1. run multiple displays (one waking up quicker than the other may be
important, I'm not sure)
2. displays should go into standby
3. displays wake up
OBSERVED RESULT
Plasma re-detects attached displays twice.
EXPECTED RESULT
Plasma should not need to re-detect displays at all, computer should be just as
I left it.
