I'm playing around with an experimental application for changing the brightness of computer screens. I started on my laptop computer and have been using
/sys/class/backlight/intel_backlight/brightness to update the brightness, but on my desktop computer there's nothing in the
Where can I find something similar to the system file
/sys/class/backlight/intel_backlight/brightness but for desktop computers with Ubuntu?
Or is there another interface for adjusting brightness on Ubuntu?
Grateful for help!
