I have GTX 970 with propertiary drivers(495) and Ubuntu 21.10
When I play via Wine at certain games like Patrician IV or Kingdom Come Deliverance, then after some time(randomly between 10s - 4h), screen turn off and later start to show random color(usually black, white or green) - I can’t do anything on OS later, music still plays but I can’t .
The problem doesn’t happens with all games. I played almost 120h without any similar crash with Witcher 3.
The problem happens both on Ubuntu 21.10 with Nvidia 495 drivers and also ~390 with Kubuntu 18.04, so this is not a problem with my OS setup.
I tried to disable/enable DXVK, turn off/on many options in Nvidia Settings and a lot of other things, but I still have this problem.
In journals, I don’t see any thing that could show what and why it exactly crashed(I don’t even know ).
Just after reboot,
I created it again, but still I don’t see any disturbing things nvidia-bug-report.log.gz (393.6 KB)
I tested game with and without specific options like esync, gamemode, lutris libraies etc., and always, sooner or later, monitors start to show random color or just turn off(computer still works).
I changed settings in game to the lowest playable settings, so I have in most of the time 60fps and 50% GPU and 50% CPU utilization, but game still crashes, so I don’t think that this is a problem with too small amount of power given to card.
