Bug ID: 381004
Summary: kwin_core: Failed to initialize compositing,
compositing disabled
Product: kwin
Version: 5.10.1
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: ber...@codewiz.org
Target Milestone: ---
All compositing effects are disabled in my desktop. Happens every time I log
in. I suspect this is a regression from Plasma 5.9.x, but I'm not 100% sure.
This system has the Nvidia proprietary drivers 381.22-2 on GM204 (GeForce GTX
970). Direct rendering works and OpenGL applications work correctly.
I can't test with nouveau due to a kernel bug affecting my particular card
(https://bugs.freedesktop.org/show_bug.cgi?id=94990).
