[COLUG] Permissions Problem

[Stephen P. Molnar]

OpenSUSE 10.3/KDE 3.5.7 new installation

Made a real mess this time.  I was attempting to change permissions on /usr 
for root/root to root/users which didn't work out so I changed the /usr tree 
back to root/root

Now, as a user, when I attempt to open a root mode Krusader I get and error 
message:  'Su returned with an error.'  The same thing happens when I attempt 
to open yast2 as root.

Assistance will be much appreciated.

Thanks in advance.
