Filip Hejsek ([email protected]) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #29 from Filip Hejsek ([email protected]) --- All the workarounds posted here are for a different bug: https://bugzilla.kernel.org/show_bug.cgi?id=210263 There are three different problems: - setting brightness doesn't work before showing something on display (the bug linked above) - actual_brightness has wrong range (this bug) - kernel uses aux for backlight control on systems that don't support it For the third problem, there is a patch in https://bugzilla.opensuse.org/show_bug.cgi?id=1180749, and it seems to be merged already. However, because there is no way yet to detect that aux backlight doesn't work, the workaround has to be enabled with amdgpu.aux_backlight=0 (assuming you have a kernel with the patch). -- You may reply to this email to add a comment.
