Hello my game compiles good and works good in ubuntu 20.04 but when running in fullscreen my whole computer crashes and reboots everytime I make the window in the game just a little bit bigger then it will crash my computer. This is a new UE4 Build, and no matter what game I make in UE4 it crashes even when play testing a blank template of a 3rd person or first person. Please help thank you very much
OS: Ubuntu 20.04
GPU: GTX 1070, driver 450.66
Dear valued Unreal Engine user,
As this is crashing the whole system it can be difficult to debug, you may be able to get more useful information out by using the Vulkan validation layers. For example enter r.Vulkan.EnableValidation=1 or launching with -vulkandebug. You can also try with r.rhisetgpucaptureoptions 1 to disable or launch with -forcertbypass -norhithread to disable parallel rendering.
If all else fails, attempting to upgrade to the most recently Engine version 4.26 or 4.27, and updating the nVidia drivers, as well as Ubuntu may help. Once you have something that is stable, you could backtrack from there if you need to solve it for other users.
Are there any other possible quirks with the system itself? For example a low powered CPU or low ram, or possibly bios settings causing issues with the GPU?
Overall though, this has a high likelyhood of being a driver issue, so usually reaching out to nVidia with a test project would help them debug.
Thank you for your continued support,
