I downloaded the previous xorg rpm's, version 6.8.1-12.FC3.21, from the Fedora
web page. I forced rpm to load the previous packages, then I erased the newer
xorg packages (6.8.2-1.FC3.13.) I should probably have done that in the
opposite order. But, I'm now running with 2 processors enabled, no
hyperthreading, in a gnome-terminal under X11.
So something about the newer xorg packages disagreed with my dual processor
system.
BTW, I tried enabling hyperthreading again with the second processor disabled.
Inexplicably, this time, the system locked up once I brought up X. I could
have sworn that that worked correctly with the 6.8.2-1.FC3.13 packages.
Thanks for the responses.
