--- Comment #19 from kurmikon@libero.it ---
I confirm that the bug is not fixed in 5.9.12.
https://github.com/systemd/systemd/issues/17826
As Poettering pointed out, actual_brightness is read-only and reports the
brightness currently in effect, while brightness is writable and reports the
value set by userspace.
Not only the actual brightness is in a different range that breaks systemd
backlight restoring service at startup, but on my device its value is also
fixed on the same value while it should reflect the correct level on brightness
changes.
Brightness at the maximum:
/sys/class/backlight/amdgpu_bl0/actual_brightness > 249
/sys/class/backlight/amdgpu_bl0/brightness > 255
/sys/class/backlight/amdgpu_bl0/max_brightness > 255
Brightness at the minimum:
/sys/class/backlight/amdgpu_bl0/actual_brightness > 249
/sys/class/backlight/amdgpu_bl0/brightness > 2
/sys/class/backlight/amdgpu_bl0/max_brightness > 255
