Bug ID: 499846
Summary: kwin is crashing whenever I plug/unplug HDMI external
LCD
Classification: Plasma
Product: kwin
Version: 6.3.0
Platform: Neon
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: p...@7gods.org
Target Milestone: ---
Application: kwin_x11 (6.3.0)
ApplicationNotResponding [ANR]: false
Qt Version: 6.8.2
Frameworks Version: 6.10.0
Operating System: Linux 6.11.0-1013-oem x86_64
Windowing System: X11
Distribution: KDE neon 6.2
DrKonqi: 6.3.0 [CoredumpBackend]
-- Information about the crash:
After update to Plasma 6.3.0 it's now crashing every time I plug or unplug the
HDMI cable (it wasn't crashing before update for last ~6 months).
If I restart with HDMI plugged in (as usual), I get both screens working in
sddm, after login the kwin crash happens [almost] instantly, other windows from
saved sessions survive, but panel is gone.
If I login with HDMI unplugged the X11 session starts w/o kwin crash (IIRC),
after plugging cable in it does crash instantly, but panel still works, so this
is workable.
Need more time to figure out what will happen after sleep/wake, etc... but
since this is crashing every time I plug/unplug, I'm just reporting straight
away.
X11, KDE slimbook (AMD Radeon 780M), notebook display 2560x1600, LCD 1920x1080,
kernel 6.11.0-1013-oem.
(not wayland, wayland makes the notebook hard-freeze within few hours, so it's
not usable at all for me, but that's different story)
The crash can be reproduced every time.
