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 ...
