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?
