This is gonna sound like a really stupid question, so please don't flame 
me TOO hard, but how can I tell what version video driver I have?  My MB 
came with an ATI Radeon X1200 series video controller.  I thought that I 
had the latest drivers on for it, but maybe I don't.  I do see a message 
when the machine boots up about running in a low-graphics mode.  Are 
these related?  Would my /etc/X11/xorg.conf file tell me the versions?

Thanks (and sorry for the stupidity: just frustrated and can't really 
think straight).
