I uninstalled the Radeon driver this am, and in the process it said it 
found an incompatibility between itself and an xorg lib with an '.so' 
ending, if that makes sense - it was about 4 am and I failed to write 
down the info. The problem remains. So, I'm thinking that I should 
revert to the previous xorg version (the current one has an ati video 
driver update included, according to what I read), and then reinstall 
the current version??? Does that make sense? If so, any suggestion about 
how to roll back an xorg version? Will the rpm -e do it?
