How do I change the screen brightness in Lubuntu 12.04?

The screen brightness is stuck in a very bright mode and it's quite uncomfortable.


You might want to take a look at your system settings -> power settings.


I dont know if you have the same settings though, since mine is mint 14...

  • Yes iǘe been going through the power settings. I can set it so that the brightness changes after so an so much time inactive etc. But no way to actually just set the brightness. – Hermann Ingjaldsson Feb 8 '13 at 12:31
