I have shuttle with an amd firepro 710 graphics card and four displays cabled with display port. The displays periodically flicker, which can be annoying. dmesg has only one amdgpu error:
sudo dmesg --level=err,crit|grep amdgpu
[ 5.501805] [drm:amdgpu_get_bios [amdgpu]] *ERROR* failed to evaluate ATRM got AE_AML_BUFFER_LIMIT
which I don’t yet understand. Any recommendations on next steps?
Here’s the configuration via inxi. Yeah, it’s a dump, but I’m not really sure what I’m looking for, so I enumerated the machine, the graphics drivers and the displays.
sudo $(type -p inxi) --edid --cpu --machine --system
