Created attachment 323500 [details] /var/log/Xorg.0.log Description of problem: Summary basically provides whole story. Switched on desktop-effects and when triaging bug 471353 I tried to prove that switching between console and X just works, I got black screen on returning to X :-). Computer was not dead and mouse was moving, but aside from the mouse cursor the screen was totally black. I was able to connect to the computer via ssh from other computer. When trying to gdb --pid=$(pidof Xorg) gdb was begun to start, printed "attaching to the process XXXXX (no debuginfo) ..." and then it froze completely. Of course, I have no /etc/X11/xorg.conf Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.5.2-12.fc10.i386 How reproducible: happened once Steps to Reproduce: 1.desktop-effects on 2.Alt+Ctrl+2, Alt+Ctrl+7, Alt+Ctrl+1 3. Actual results: black screen with mouse cursor moving Expected results: lovely Xorg display with Firefox where I could continue explaining to the reporter that our Xorg Just Works™

I would add, that not only gdb lead to total freeze, chvt (iirc) did similar result. Or killing X, not sure...
This has evaporated somewhere.
