acer

I have an acer aspire as5750. With the intel hd 3000 graphics.

When i use the adjustment function keys the dial moves but it doesn't translate to the screen diming. Same with the dial in linux settings.

Also in colour settings it seems there is no colour file or icc profile available for this laptop. Do you think if i can get a working icc profile then it will fix this or not? I have found something that could work:Argyll but it looks complicated to use, has anyone here used it? Would it allow me to dim?

Or is there any other work around? I have searched lots but can't find a solution.
