I don't know the solution to the problem you are having, I can only give some tips from experience. My first trouble shooting step would be to use fglrx and see if it makes a difference. The you know if it's a driver issue or not. You don't have to keep using fglrx, consider it a debugging technique... I do recall having issues with that card and xorg 7.0, but it was a long time ago so I don't remember details. Whatever it was went away with emerging 7.1 and using the latest ati-drivers. Which wm do you use? alan -- gentoo-user@gentoo.org mailing list
