Blender hangs gnome session
I am experiencing the same issue as the bug reported here: #2097 (closed).
When running blender, it will freeze the display after a short period of working. The actual steps to recreate it don't appear to follow an exact pattern, but it will generally freeze after a few minutes of activity. When it is frozen, the mouse still moves, but no action can be initiated. Although the screen continues to show the blender screen, the program has actually crashed and is no longer running.
My only resolution is to switch to a console (ctrl-alt-F3) and kill everything to force a new login session.
It has only recently started, and I suspect it was an upgraded driver. I have tried running blender 2.81 and 2.83 and the latest 2.83.2 build. The earlier version used to work perfectly (including the 2.81 version I tested above).
I have run blender under both XOrg and Wayland, and have booted into a few older kernels too I get the error with all of them.
My current machine is a fairly recent Huawei MateBook X. running Fedora 32. I have the NVidia drivers installed, but the modules are not loaded in memory at all during this activity, and haven't been since a fresh power cycle.
