Bug ID: 448503
Summary: Secondary monitor has black screen when waking from
sleep with wayland on 5.24 beta.
Product: kwin
Version: 5.23.90
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: kdebugrep...@protonmail.com
Target Milestone: ---
SUMMARY
***
When waking my PC from Idle/Standby, and using the new primary monitor feature,
my secondary monitor loses interactivity and the wallpaper is black. Enabling
and disabling the monitor or power cycling it returns the monitor to the
appropriate state. My main monitor takes awhile to wake from standby and I
think that is the cause of this issue, as my desktop first appears on the
secondary monitor and then stuff gets shifted over, thus the secondary monitor
has this problem.
***
STEPS TO REPRODUCE
1. Have a monitor that takes awhile to wake from sleep that is the primary and
a secondary monitor that is "quick" to wake from sleep.
2. Wake the pc from standby (monitors off to on)
3. Observe bug.
OBSERVED RESULT
Secondary monitor's desktop is not interactive and wallpaper is black.
EXPECTED RESULT
No loss of functionality while respecting my primary monitor choice.
