Backtrack 5 R1 with ATI Radeon HD 6850 - Window redraw lag
I just installed the ATI Radeon HD 6850 from ATi's website and its working fine other than window redraw. When I move a terminal window (or any other window) I get very slow and laggy window redraw. I don't however have a problem with scrolling in non OS related programs like FireFox but I do experience window redraw lag in the file browser when I scroll. I cant figure out what is wrong. I have followed some tutorials on how to fix this problem but none have worked. I have edited my Xorg.conf file and tried to reinstall the drivers but nothing seems to fix this problem. I would like to point out that I am very new to using linux, but I am very willing to learn. I would greatly appropriate any help that anyone could provide.
