Blender was working fine for me recently, but now I'm observing a problem. Blender 2.81a and 2.79 seem to have the same issue. using cycles I get a crash as soon as I select GPU from the list of rendering devices. I don't even start rendering, it crashes just by selecting GPU. I went to check settings (do not recall if its set to GPU or GPU+CPU) only to find that clicking the System tab in settings also causes an instant crash. The computer is updated regularly, but I don't know when the issue showed up. How can I troubleshoot this?
on the console the only piece of information it seems to give me is "segmentation fault"
OS is Ubuntu 18.04LTS
