Jim: Just to let you know that this worked perfectly! It would seem that 
there is a concatenated series of actions that led to this mess. The 
first was the installation of the Radeon driver from ATI. This was 
followed by the application of xorg-x11-6.8.2. I've now rolled back the 
process by first removing the Radeon/ATI driver, and then by rolling 
back xorg. During the removal of the ATI driver, I got a message about a 
conflict between that driver and something on my system which I 
unfortunately didn't write down. So, my question is, do you think I 
should try reinstalling the xorg update now that the system is working 
again?
