Hi, i have a aspire as5750 which is running the intel hd 3000 graphics. Ubuntu 11.10.
I have tried using the function keys and the screen settings in ubuntu. When i use the function keys a little dial shows up and it seems to be adjusting on the dial but it isn't changing my screen brightness. Same with the dial in ubuntu settings.
I have tried searching this forum and elsewhere but it's hard to know what to do still. Because i'm not sure what posts were only relevant to the specific laptop/ubuntu version/graphics they were using.
But really the screen is too bright even for general use at normal angles. if i tilt the screen back far the colours look much better. But also i want this so i can save power as well.
Also in the colour settings i can't change anything because it is un-calibrated. "The measuring instrument is not detected please check it is turned on and properly detected."
