This photo is of one of the two screens attached to the ATI Radeon 5870 under Natty.

All latest updates have been installed.

The system is still responsive as I can Ctrl-Alt-F1 and see a change in the screen and then ctrl-Alt-F7 reverts to the image here.

However, on some reboots the system hangs. Caps-lock LED on keyboard does not toggle indicating a complete hardware lockup.
