I am running CentOS 6 with a 780M integrated graphics using fglrx 11.7 or 11.8 with an e-machines e182HL monitor on VGA. with both drivers, after install fglrx the login screen and the gnome desktop after logging in is afflicted with horrible black flickering lines running up and down the screen. Turning on tear-free desktop fixes the problem... but it messes up full screen flash playback.

Any ideas?
