As soon as you log in, either Unity or GNOME kicks you back out to the login screen
When I try unity in alt f1 console, I get this error
compiz error couldn't load plugin /usr/lib/compiz/libccp.so: libcompiz_core.so.ABI-20120216 not found
Ahh...yes. Ubuntu decided that it was okay to break the ABI once again. A completely upgrade in the order of the README file should solve this.
In that case, could you open a bug report on that? It would be great if you could provide the output from the update script and the list of packages that actually need to be updated.
With Links? That must be pretty annoying :D
Reinstalled everything, still no joy
It's weird how the Compiz ABI bumps always cause problems on your computer. I always test the updates on 2 computers and a virtual machine and I can never reproduce it :(
Okay, I've bumped the revision of all of the compiz packages to force an update on all of them. Could you try compiling again? (in this order)
