View Full Version : [ubuntu] Brightness Doesn't Change HP DV6

June 12th, 2012, 04:33 PM
I have an HP dv6.

I am trying to change the brightness on the screen.

The brightness keys work (meaning it changes the brightness slider), and I can verify that the brightness integer in


changes from 0 to 10.

However, there is no physical change on my monitor.

Could it have something to do with this laptop having 2 GPUs (an Intel and AMD)?

Any help would be appreciated. Thanks!

I believe there are some issues with the backlight in the Intel drivers at the moment. The xorg-edgers ppa might help (although it didn't for me.)
