This is an AMD Renoir system, with AMD Ryzen 5 4500U APU, This happens only, if I set 'quiet' as boot option. If I remove it, brightness restore works fine. If I boot with quiet set, after login I can do systemctl start systemd-backlight@backlight:amdgpu_bl0.service And it will successfully restore my brightness level. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
