Description of problem: After upgrading to current "rawhide", screen flicker occurs whenever some GNOME application is launched but not in the case of plain X applications. The issue appears to be due to repeated probing (xrandr?) as corresponding sections in Xorg.0.log indicate which are appended continuously as the flicker occurs. Version-Release number of selected component (if applicable): xorg-x11-drv-ati-6.8.0-14.fc9 How reproducible: Always. Steps to Reproduce: 1. Log in to GNOME. 2. Launch gnome-terminal, gedit, etc. Actual results: Screen flickers when application window appears. Expected results: No flicker. Additional info: - I'm not aware of this happening before upgrading to post-F9 "rawhide". - Launching xterm, etc. does not trigger this behaviour. - After merely logging in to GNOME, it takes about 20 seconds during which the screen keeps flickering until the GNOME desktop eventually appears. In $HOME/.xsession-errors, the following warnign appears: ** (nautilus:5003): WARNING **: Unable to add monitor: Not supported - gnome-session-2.22.1.1-1.fc9 gnome-settings-daemon-2.22.1-1.2008.03.26.8.fc9 haven't been updated because otherwise nautilus won't come up at all or cannot be updated because of broken dependencies respectively.

*** This bug has been marked as a duplicate of 438734 ***
After reverting the system to a fully updated F9, the issue is gone. At login, the screen flickers a couple of times. After that, everything behaves as expected. Driver is still xorg-x11-drv-ati-6.8.0-14.fc9.x86_64.
Reopening since bug 438734 is an F9 bug whereas the present one is a post-F9 bug.
Same issue with intel_drv from RawHide (updated today) xorg-x11-drv-i810-2.4.2-1.fc10.i386
Seems to have been resolved for me with todays rawhide. xorg-x11-drv-i810-2.4.2-3.fc10.i386
