This, of course, is the challenge.
If it can be done then the problem is solved.


NAME

shazam -- magically rationalise graphics cards

SYNOPSIS

shazam cardname graphics-program-name [ graphics-program-options ]

DESCRIPTION

Can only be run by root.
It saves the current graphics card state information
and forks graphics-progam-name with graphics-program-options.
When graphics-program-name terminates, for whatever reason,
shazam restores the graphics card to the same state it
was in before graphics-program-name started.

EXAMPLE

shazam GoodCard xserver-GOOD -bpp 16 &

BUGS

Works well for GoodCard and VeryGoodCard2000.
Fails miserable on any card that can be set into
a state such that to leave that state you must
know what state it is in. For such cards the
knowledge that it was once in a particular state
is not useful.

The cards for which shazam is not useful include:
S3-yada-yada
ATI-blah-blah
some others
