I was running kernel 5.13 on Ubuntu 21.10 and w= hen I upgraded to mainline kernel 5.15.13 (using https://github.com/pimlie/ubuntu-mainline-kernel.sh), the service "systemd-backlight@backlight:amdgpu_bl0.service" starts as expected and backlight seems to be restored. With kernel 5.13 it failed: "Failed to start Load/Save Screen Backlight Brightness of backlight:amdgpu_bl0" and I was not able to start it manually. --=20 You may reply to this email to add a comment.
