Re: how can i solve this? NV-CONTROL extension not found on this Display.
I have the same exact problem:
Suse 10.1 + XGl on a 7400 with latest driver.
I'm running this on a laptop, so it's really annoying : i have no hardware way (button on the screen) to change the brightness of the screen !
Please provide us with a solution to be able to change brightness under XGl !!!!
