Can you explain a little bit more please. When you say you have installed FullMonty into
your existing 2010.11 KDE setup what do you actually mean by that?
Do you mean you installed FullMonty on "top" of 2010.11 / partition or into separate partitons?
I did create a new user and have it working, but can't get access to my original /home directory as a regular user.
Thats as it should be - that user shouldn't have the permission to access your original home partition unless given permission rights by root privileges
