Whatever I do, I can't get Ubuntu to play nice with my video card. Anything video related takes up over 100% of my CPU using dual screen HDMI (either VLC, compiz or Chrome). Is Ubuntu just no good with my video card? I can never find any info on my specific video card on the ATI website. Any info or help would be greatly appreciated.
