I do it all the time without ever using xhost. su to root (not 'su -') and
you should be able to launch graphical apps. I use gparted a lot. I assume
that you mean a console/terminal inside an X-session.

BTW, it's pretty easy to change the logo in xdm, and I'll tell you if I
can remember where the file is. That install is gone already.

I didn't figure out how to change the words. Maybe it's another graphic. I
was looking for text. Anyway, check out the .xpm files in /etc/X11/xpm (I
think it's there and not /usr/share).
