Access DISPLAY after 'su -'

Hi,

I've been able to use the same DISPLAY ':0.0' for myself and after I su as
root. I don't know how I did it, but it did work until RedHat 9
(XFree86-4.3.0-2.90.43).

But now, I'm in Debian testing (X is xfree86 4.3.0.dfsg.1-1), and I can't
use DISPLAY ':0.0' any more after I su as root.

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

How can I fix it?

I found one option after googling, but it is "use ssh" -- I don't like
it:

- it's a overkill
- allowing root to ssh in is not suggested

So, can anybody help?

Thanks

Maybe "export XAUTHORITY=$USER/.Xauthority" before you su, or maybe
do this in your .bashrc?
