I am experiencing exactly the same problem as macat. I have Kubuntu Hardy on a Dell Inspiron 6400 with a Intel 945 graphics card and the laptop is connected to an external monitor (1680x1050). I always turn off the laptop monitor (usign xrandr). The external monitor suddenly goes black or grey after some time. I have noticed the following when this happens:

1) There is no mouse pointer, the external screen is completely black or grey.
2) Ctrl-Alt-Backspace restarts the X-server but does not correct the problem (still black screen). A full reboot corrects the problem.
3) Ctrl-Alt-F1 takes me to a console in the laptop screen.
4) The external screen sometimes flickers for a second.
5) I did not have this problem under Kubuntu Gutsy.
6) I do not know if its related but yesterday the whole X-server crashed and could not be recovered with any of the above.

I attach the requested outputs. Thanks for any suggestions.
