I just experienced this bug as well when upgrading from Intrepid to Jaunty. Except I was using the "ati" video driver with Intrepid, and for some reason the upgrade process installed the "fglrx" video driver and this broke X. The gdm-log had the following to say:

/usr/bin/X: symbol lookup error: /usr/lib/xorg/modules/extensions/libdri.so: undefined symbol: atiddxAbiDixLookupPrivate

giving up.

I solved the problem by purging everything fglrx-related and reinstalling "libgl1-mesa-glx" and "libgl1-mesa-dri":

  sudo apt-get remove --purge xorg-driver-fglrx
  sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri
  dpkg-reconfigure xserver-xorg

taken from this guide: https://wiki.ubuntu.com/X/Troubleshooting/FglrxInteferesWithRadeonDriver (linked in Bug #345669).

It seems to me that this is a bug in the upgrade process of Ubuntu. If it hadn't installed the fglrx-driver, I assume everything would have worked fine. At least it did after removing the fglrx-driver.
