Thanks for posting this advice.  I too had the same problem.  I think
the key step was 

md5sum /etc/X11/xorg.conf | sudo tee /var/lib/xfree86/xorg.conf.md5sum

I did the reinstall, and was prompted for this afterwords.  That should
have been run automatically as part of the security update, IMHO.  I
think the average non-geek would have been up the creek.
