[...] Hi, that was all good advice. I'd add that before making a bug report, I'd suggest checking something like: $ sudo journalctl -b -g 'not supported' because if the GPU driver is reporting that certain graphics capabilities are not supported, then the bug would be in the software that attempts to use those capabilities when they aren't available. And if the graphics hardware is old, then response to that bug report is likely to be "if you want that capability, you will need to upgrade your graphics hardware". For example, on this system, I see: [david@kablamm ~]$ sudo journalctl -b -g 'not supported' Apr 08 08:55:21 kablamm kernel: kfd kfd: amdgpu: OLAND not supported in kfd Apr 08 08:55:21 kablamm kernel: amdgpu 0000:01:00.0: amdgpu: Trusted Memory Zone (TMZ) feature not supported Apr 08 08:55:21 kablamm kernel: amdgpu 0000:01:00.0: amdgpu: PCIE atomic ops is not supported
