Hello, i installed Mountain Lion on my Alienware M17x R2 and with some kexts everything seems to work, except a strange issue with my video card.
It's hard to explain, so i made a video about it: http://www.youtube.com/watch?v=3TaTy4p_HGQ
In fact, when i change resolution, or a game does that, it happens this strange thing. Same thing happens when I wake it from sleep (even if only monitor sleeps).
I was told it can be solved with a dual link fix, i tried to apply what i've found here but the issue is not solved. The only resolution that works is 1440x900 which is the screen's native one (i've read that dual link patch is needed for resolutions higher than 1440x800 so i'm not sure that this is the issue).
Any idea?
Oh, not a real issue, but also backlight control is not working. As said it's not a problem for me but if someone has any idea, i'd appreciate
