Then I misunderstood situation as if the backlight control didn't take any effect. Now I refreshed the OBS KMP repo to contain the possible fix. It's being rebuilt, and please give it a try later. The rpm changelog should contain the entry like: - Add a proper fix (attempt): 0001-drm-amd-display-Fix-the-brightness-read-via-aux.patch At first, uninstall the previous KMP, just do "zypper rm amdgpu-dbg-kmp-default" Then re-install the new rpm, run mkinitrd and retest. This doesn't contain the debug prints, so report back whether it works or not. -- You are receiving this mail because: You are on the CC list for the bug.
