Well thanks for that. I was actually thinking about removing the nvidia
As it happens, I gave up on the machine for the moment and went to work. I
therefore no longer have physical access to the machine. I can, however
ssh into it. While I was wondering about removing or re-installing the
nvidia driver I noticed that there is a new kernel available in yum
(3.1.5-1.fc16.i686.PAE) so I did a yum update. This will of course cause
the akmod module to rebuild the driver.
I have rebooted, and the encouraging thing is that dmesg now has no
reference to a gnome-shell segfault!
Unfortunately I will not be home again until Thursday evening so I can't
actually try to log in to gnome-shell to see if it has worked (are there
any command line tricks to test if gnome-shell is working?).
Thanks for the help so far. Any other advice, hints or tips will be
