One of the things I have learned about LinuxMint is that you can install the product to a USB drive on one machine and run it on another if you replace the /etc/X11/xorg.conf file with the correct version. (I steal it from the LiveCD boot up.) I have played this game with Bianca and Cassandra across five different computers.
I do this to keep one logical machine that I can run on any of the physical machines that I have access to. Maybe it is just dumb luck but I haven't had a problem with the GUI yet.
I have a computer that has stumbled on the audio configuration and I hope that there is a similar file and that someone out there knows which one it is.
