The Debian sid install on my Lenovo T450 allows control over the brightness via
In dark environments, the minimum brightness setting is too dim for me, however min brightness + 1, is too bright.
/sys/class/backlight/intel_backlight/brightness" allows me to read the current brightness setting, and using
echo 16 > brightness, i can set my ideal brightness.
Min brightness = 1 Max brightness = 851
I've also found that setting brightness to zero appers to disable the backlight entirely.
Is there a way to somehow configure brightness hotkey behavior in Gnome?
