Hey Todd,
Thanks for the excellent tip. I followed your instructions to log in
and then log out to restart GDM. It worked great. Now I've got a
screen resolution of 1280 x 1024 with all the little letters right where
you would expect them to be.
I installed the elrepo then installed the kernel. I had to edit
/boot/grub/menu.list to make the new kernel the default but that's all
it took. Life is good and I can stop messing with this old clunker and
return it to it's rightful owner for resale.
