I'm running Ubuntu 8.04, which 95% of the time works just great.
The other 5% if the time, the screen will just go grey when in use [It may actually be black, but with nothing else on the LCD to contrast it against it looks grey], and I'm unable to do anything (*).
Ctrl-Alt-Backspace will rattle the disk, and I can hear the Ubuntu drumbeat that happens when GNOME starts, but nothing actually changes on screen.
Ctrl-Alt-F1 will drop me to a command line; restarting gdm from here doesn't do anything other than re-present me with a back/grey screen.
So any ideas from the readers as to the best way to restart my windowing environment without restarting the whole box?
Thanks,
Greg

Googling suggests to me that this is a fairly recent, err, feature, of the current packages ...
