Background

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 /sys/class/backlight directory

Question

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!

Some interfaces exist, you can find them here.

The DDC protocol (apt-get install ddccontrol) should do the trick
