You can remove the error by masking `systemd-backlight@backlight:acpi_video1.servic= e`. The amdgpu_bl1 error is probably the bug i linked earlier - https://bugzilla.kernel.org/show_bug.cgi?id=3D210263. Do you have silent bo= ot? If yes, you need to print something to console before setting backlight during boot. You can use the workaround i posted here: https://bbs.archlinux.org/viewtopic.php?pid=3D1971198#p1971198. If you use = my workaround, make sure to remove other workarounds you may have applied for = that error (like another service that runs systemctl start systemd-backlight@backlight:amdgpu_bl0). --=20 You may reply to this email to add a comment.
