Bug ID: 482429
Summary: kwin_wayland crashes on single hdmi screen reconnect
Classification: Plasma
Product: kwin
Version: 5.27.10
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: al...@zenfolie.org
Target Milestone: ---
SUMMARY
On a desktop with a single monitor attached, when the HDMI cable is
disconnected (or, in my case, the kvm switch switched to the other computer)
and later reconnected, kwin_wayland crashes.
STEPS TO REPRODUCE
1. Unplug, or hit the KVM switch, while a session is active.
2. After a little while (presumably long enough for an attempt to put the
monitor to sleep has been made), reconnect the monitor.
OBSERVED RESULT
kwin_wayland crashed and dumps its core.
EXPECTED RESULT
kwin_wayland doesn't crash.
