Many thanks for the hint. I have removed the kernel parameters radeon.cik_support=0 amdgpu.cik_support=1. I can confirm that this setup is working for me, too. It works on both, X11 and Wayland. I have compared the two inxi -GSaz outputs (with radeon.cik_support=0 amdgpu.cik_support=1 and without): 6c6 < loglevel=3 radeon.cik_support=0 amdgpu.cik_support=1 --- > loglevel=3 9c9 < Tumbleweed 20240419 --- > Tumbleweed 20240429 11,12c11,12 < Device-1: AMD Kaveri [Radeon R7 Graphics] vendor: ASRock driver: amdgpu < v: kernel alternate: radeon arch: GCN-2 code: Sea Islands --- > Device-1: AMD Kaveri [Radeon R7 Graphics] vendor: ASRock driver: radeon > v: kernel alternate: amdgpu arch: GCN-2 code: Sea Islands So, now the kernel loads the radeon module by default. I have two questions where I would appreciate your feedback. - Since I had never investigated in that before, is this the desired behavior, such as for new installations? - Shouldn't I/we/all rather stay with amdgpu (by considering the information on 'https://wiki.archlinux.org/title/AMDGPU'?
