If you su to a user from root, e.g. sudo su - <username> ... you generally don't
need to type in a password.  However, su does require a valid (not locked,
password not expired, account not inactive) account, even if you run it from root.

Typically, people SSH in to a system and with "ForwardX11 yes" enabled, assuming
you're using an OpenSSH client.  This will set up your shell so that X is
tunneled over SSH.  X applications "just work" and the session is encrypted via
tunneled SSH.

Since you're performing an su to another user, you'll have to make sure your X
environment is set up correctly.  Check the DISPLAY environment variable etc.

I'm assuming the theme is located in a hidden directory under your home
directory.  Something like ~/.galeon.   If the $HOME environment variable is not
being set, the application won't find the user's theme.  I'm not familiar with
galeon so I can't be more specific.

Thanks,
