Bug ID: 503870
Summary: When night color is toggled or adjusted, freezes one
monitor and says 'kwin_wayland_drm: Pageflip timed
out! This is a bug in the nvidia-drm kernel driver'
Classification: Plasma
Product: kwin
Version: 6.3.4
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: core
Assignee: kwin-bugs-n...@kde.org
Reporter: a...@digitalsignalperson.com
Target Milestone: ---
SUMMARY
On my desktop I just switched to using an RTX 5070 Ti. I noticed that when
night light was enabled by schedule, one of my three monitors froze. After I
log out and log back in, everything is back to normal. But any attempt to
adjust night color settings results in the same thing repeatably.
STEPS TO REPRODUCE
1. Have three monitors
2. Enable, disable, or change the strength of enabled night color
OBSERVED RESULT
One of the three screens becomes frozen. The journal starts spamming this every
1 second or so:
kwin_wayland[115930]: kwin_wayland_drm: Pageflip timed out! This is a bug
in the nvidia-drm kernel driver
kwin_wayland[115930]: kwin_wayland_drm: Please report this at
https://forums.developer.nvidia.com/c/gpu-graphics/linux
kwin_wayland[115930]: kwin_wayland_drm: With the output of 'sudo dmesg' and
'journalctl --user-unit plasma-kwin_wayland --boot 0'
EXPECTED RESULT
No frozen montiors
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux, kernel 6.14.5-arch1-1
KDE Plasma Version: 6.3.4
KDE Frameworks Version: 6.13.0
Qt Version: 6.9.0
ADDITIONAL INFORMATION
Using nvidia-open driver package on arch linux, as required for the newer gpu.
Googling for "kwin_wayland_drm: Pageflip timed out! This is a bug in the
nvidia-drm kernel driver" shows a lot of recent results, and not much for
solutions.
Interesting here is a repeatable trigger by night color.
