I have not had this problem but the last two Radeon-fglrx installations have been problematic. Most times reboots would result in X failing and the system dropping to runlevel 3. When it succeeded, windows would ghost when dragged across the desktop.
I have decided to give up on radeon/fglrx. I fixed one of them with an nvidia 710 and I just ordered another one to fix the other. On 03/31/2016 01:18 PM, Stephen Isard wrote:
I have a Dell Optiplex 980 with a Radeon HD 6450 card which was working fine with the elrepo fglrx-x11-drv and kmod-fglrx packages until I recently upgraded to kernel 2.6.32-573.12.1.el6.x86_64 and fglrx versions 15.12-1. Now when I move a window on the screen, the content isn't erased from the old location, leaving a trail of ghosts behind. This happens with more than one window manager (fvwm, icewm, fluxbox), so I think its an X problem, rather than a window manager bug. The guys at elrepo were very responsive, but they didn't have the problem on their own machines, and it's not really their software - it is closed source from ATI - and they have run out of guesses for what to try. I have tried installing ATI's own rpm and that behaves the same way. I've filed a bug on the unofficial ATI bugzilla, but don't have great hopes there. I'm wondering whether anyone here has ever seen symptoms like these. Using the radeon driver gets me a mostly usable system, but there is some stuff that says it won't work without glx.
