Yea, I saw that, but I expected SOMETHING there. I'm not sure where  
else that data would be kept.

Never used the program before, but I agree with you, yes.

Ummmmm.  :-(  It's an on-board video circuit going to an Envision  
multisync monitor.  :-\

At this point I'm assuming I can use the vesa driver.

Unless anyone else comes up with some particular ideas I'm first going  
to see if I can install 8.04 on it. If that doesn't work, I'll  
reinstall Fedora 10 on it and see what kind of data I can get from  
that installation before trying Ubuntu again.
