Bug ID: 367766
Summary: Compositing won't start with Nvidia 370.23 drivers on
Quadro card.
Product: kwin
Version: 5.7.3
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: discostar...@gmail.com
Latest (370.23) update to Nvidia drivers seems to have broken compositing on my
laptop with a Quadro card (NVIDIA Corporation GK104GLM [Quadro K4100M]). My
desktop with a GTX1080 seems to be unaffected by this issue.
BIOS has been configured to only use the Nvidia card.
Note that at least one other Arch user has seen the same issue:
https://bugs.archlinux.org/task/50500
Reproducible: Always
Steps to Reproduce:
1. Login to KDE with Nvidia Quadro card.
2. Note that compositor is not running.
3. Use Alt+Shift+F12 to try and turn on compositor. Screen sometimes visibly
flickers, but compositing not enabled
4. Try to turn on compositing in system settings. Compositing still does not
enable if any of the opengl options are selected.
Actual Results:
Compositing does not turn on if using any setting other than XRender
Expected Results:
Compositing should work. Worked with previous driver (367.35).
When trying to enable compositing, the following is dumped into
.xsession-errors:
