Overall it went better than expected.  The quad-core made quick work of the install, completing in about an hour and a half.  After the reboot there was a few problems to take care of.

First up is a known bug with 8xxx series Nvidia cards and Compiz.  Basically all the drop shadows are pink and/or yellow in color.  Needless to say this is a bit annoying.  To fix it simply create a new symlink by entering the following code into your terminal.

After this all you need is to restart Xserver with CRTL+ALT+BACKSPACE. Of course make sure you have properly closed any open applications that might suffer data loss.

The other mildly annoying piece is the upgrade of Avant Window Manager (AWN). It appears that the version in the repository isn’t directly compatible with the plugins of yore and there is no plugins available from the repository. For now I have decided to live with out the plugins.

Besides these minor problems that where related to either 3rd party apps (AWN wasn’t in the repository in Gusty) or proprietary drivers (come on Nvidia, open it up! everyone is doing it) the install went very well.  With today’s announcement I think Hardy may be staying on the quad-core for a long time to come.
