getting out of x

[Joel Grimes]

Noob question here - and forgive me for ranting, but it's just KILLING me!

How do I get the hell out of X?  I've become so frustrated with that 
damned automatic-restart-x thing that i wanted to resort to violence.  
When, out of desparation, I hit ctrl-alt-backspace it keeps reloading 
it.  When I do that you'd think it would GET THE POINT THAT I WANT OUT!  
(arg!.... I feel better now)
