disregard my before email! sorry.
I've just tried:
1- export DISPLAY=:0.0
2- xauth -f path list
xauth: creating new authority file path
but the same error occur when I run xterm
Warning: This program is an suid-root program or is being run by the root user.
The full text of the error or warning message cannot be safely formatted
in this environment. You may get a more descriptive message by running the
program as a non-root user or by removing the suid bit on the executable.
xterm Xt error: Can't open display: %s
If you're logged in as root, then the X libraries (from ~10 years ago)
will ignore the $DISPLAY variable. It used to be a reliable workaround
to simply use the -display option (but I've seen a few machines where
that's been broken). That is
xterm -display :0.0
As noted, if you were using ssh -X, then the display would be set
more/less automatically.
With RHEL 5.6, it's unlikely that xterm itself is setuid, since Red Hat's
been using utempter since RHEL 4.x - but on the odd chance that someone's
"fixed" your machine, stripping the setgid bit (or setuid...) won't do
much more harm than disable utmp updates.
