nouveau + GeForce GTX 970M, how to adjust backlight brightness?
Open, Needs TriagePublic

Description

Is this unimplemented in nouveau? I can change /sys/class/backlight/acpi_video0/brightness but nothing happens. The display remains at full brightness.

Hm, I need to try redshift which offers multiple adjustment methods.

Redshift doesn't work either. I guess nouveau is not mature enough yet.
