Command Line LCD Brightness Adjustment
Posted on 29 October 2007 by admin
I’ve been running Ubuntu on my Laptop since the day I got it (back inJuly). I recently upgraded to Gutsy and noticed that my brightness adjustment doesn’t work the way it used to. In fact, not at all. Here is how to adjust the brightness from the command line until this is repaired.
Just open up Terminal and type;
sudo echo –n 100 > /proc/acpi/video/VGA/LCD/brightness
This will make your LCD screen the brightest possible. If you don’t want it that bright just replace the 100 with another number. It is based on percentage so if you used 50 it would be 50% as bright as the full 100. Simple.
