different startup scripts

[Hamish Low]

Thanks Gustin,

I'm not using flgrx because it's in failsafe, flgrx only starts up if I 
go into ubuntu normally. 

I'll try your suggestions.

What would be the best way of enabling different startup scripts, either 
for a different session or a different user so I could specify a low-CPU 
2d ubuntu for when i want to make music (after selecting the rt kernel 
on startup).  The more automatic all this is the better.
