Solving problems with ncomputing in Ubuntu 12.04

Using synaptic package manager (sudo apt-get install synaptic) I was able to find the Xorg meta package which is listed as "Xorg" then by going to the "packages" menu at the top of synaptic, drop down, and select force version. I had my luck with the older version " 1:7.6 12ubuntu1 (precise) "
Synaptic will warn you that it is removing and installing a bunch of packages. That's just the downgrade of all the packages comprising the xorg meta. We end up with what's likely what the nc modules are built against, so everything seems to work fine.

Hopefully this helps until nc can update the installer.
