In similar circumstances, I would be suspicious that the X.org update was the root of the problem if the problem started before downloading/installing the ATI video Driver. If the blanking was noticed after installation of the ATI driver, then I would suspect a mismatch between that driver and your fedora system.David Curry wrote:

For no explainable reason, my graphic interface has gone crazy. It flashes to black for a moment everal several seconds. Nothing else seems to be affected. If I'm typing, words keep getting put in the doc. Downloads continue, etc... I loaded some of the latest patches/updates last night. Apart from that this machine was idle all day. It's up on the net with Firestarter providing pretty strict rules. I just tried downloading/installing the latest ATI Radeon 9200 video driver from ATI. I searched the list for similar behavior, but couldn't find anything. What could have changed in my absence??? Have I been hacked by someone?Claude, have you tried switching to a console window to see if the periodic flash to black occurs there as well? Try ALT-F2 to see if the blackout continues and then ALT-F& to switch back to your X window.
Have you recently applied X.org updates to your system?
Console is stable. X.org was updated by yum update two nights ago.
It has been a while since I looked at the ATI site, but unless things have changed the ATI drivers are only available in binary packages and compiled for an earlier kernel than that used by fedora core 2 or 3 and compiled for use on the XFree86.org window system. I expect the experts will correct me if I am wrong here, but I *think* it may be best to stick with drivers built for the xorg-x11 X Window system provided with FC2 and 3. Further, you should be aware that several fedora users have reported problems using ATI 3D cards.
In any event, you might want to double check your system's video card and monitor settings. I *think* you can do that from a terminal command line by entering system-config-display as root (using su - to setup proper path environment).
