gfx install from CD :
in X setup there is a "Test this configuration" button.
If the user answers NO to the "Can you see this message ?" dialog ( altough
I can't understand , why would he do that , a question like "Is the pitcure
properly displayed ?" would be more useful ) , or the dialog times out or
the X screen doesn't come up , nothing happens , not even a message like
"This mode doesn't work" or something.
