How to reproduce
-----
1. Watching some movies in MPlayer on Thinkpad T61
2. Firefox & Transmission running in background (may not be relevant)
3. Screen suddenly went black - as in no-power black (no backlight).
4. Connected external screen - no signal
5. The Thinkpad Fn-F7 (screen swap) function does not change state.
6. Switching to any of the virtual TTY screens (Ctrl-Alt-F2 thru Ctrl-Alt-F6) does not show any change.
7. Ctrl-Alt-Del reboot successfully shutsdown and restarts system.  Video resets and displays on both internal and external connections.
8. System starts up, login and ABRT reports a number of crashes in kernel.

Mass close of abrt reports against F14.  Please update to at least F15, and reopen if this issue still occurs for you.
