Hi,
I've searched through the BBS and amdgpu bugreports, tested some kernel commandline parameters like amdgpu.gpu_recovery=1, switching to DRI "2", but no solution yet.
sometimes checking "too simple" things could fix issues. The issue was caused by a loose connection of the HDMI cable. But somehow strange IMHO that it still worked with amdgpu.dc=0 and on Win10.
Best regards Bjoern
