Every time when I want to launch X11 programs such as mozilla from a user's terminal, I have to copy .Xauthority of that user into root home dir first.
Otherwise the error occur:
Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
(firefox-bin:1718): Gtk-WARNING **: cannot open display:
Is there anyway to launch X11 programs directly from the user's terminal after su root ?

That happened to me when I used kdm. If you start X with either startx or gdm, that does not happen (at least it worked for me).

1st method (short):
when login as root:
export DISPLAY=:0.0
export XAUTHORITY=/home/other_user/.Xauthority2nd method (long):
- install ssh
- change sshd config to enable X11 forwarding
- (mandatory for security) block ssh from outer hosts with your firewall
- run sshd at startup
- login with:
ssh -X -l root localhostOffline

As your user that is logged into the console, add a
xhost +localhostto your .xinitrc file (you may need to add this to some other startup script if you use gdm/kdm/xdm).
Then as your su'd user, just enter
export DISPLAY=localhost:0at your shell.
This is probably the the preferred way rather than pointing to another user's .Xauthority file.
