--- Comment #7 from nyanpasu64 <nyanpas...@tuta.io> --- I've also gotten corrupted VRAM when sleeping my system. I fixed it by creating `/etc/modprobe.d/nvidia.conf` with contents `NVreg_PreserveVideoMemoryAllocations=1`, then running `sudo systemctl enable nvidia-suspend` and rebooting. However I still can't enable compositing after sleep-wake with compositing off, with the same error: libkwinglutils: GL error: context lost kwin_scene_opengl: OpenGL 2 compositing setup failed ... Additionally, if I sleep and wake with compositing on or off, Firefox and System Settings (the "Quick Settings" screen's bottom bar, or the entire window) sometimes still turn or flicker black. I'm not sure if it's a KWin or Nvidia issue. -- You are receiving this mail because: You are watching all bug changes.
