Copied the xorg.conf file to xorg.conf.bkup just in case something went 
wrong. When I removed the "SubSection Display" Ubuntu defaulted to a 
generic LCD monitor and a Vesa graphics card. When I logged out and went 
back in, I got the same Log in loop (log in with UID and PWD and after 
the HD churned for a bit, it would come back to the same login screen. I 
replaced that xorg.conf with the xorg.conf.bkup (minus the .bkup, of 
course) but things just got worse. Even though there were other 
resolutions present, I could only get 640x480.

I tried xrandr -s 1024x768 but was told the the Display could not be 
opened. So I tried export DISPLAY=0
    export XAUTHORITY=/home/<usr>/.Xauthority and then the above xrandr 
-s 1024x768, but the only resolution that it would recognize was 640x480.
