That's quite fine :)

Just a wild guess, since I don't see why you should have problems
running programs like:
Can't open display: xenon:0.0
Are you running X11 as a plain user and having problems to run programs
*after* using su(1) to become root or does this happen for all users in
all terminals?

Hi Giorgos,
I am trying to run a program from xterm as a normal user. However, when su'ing in xterm,
I am unable to run any programs. Then I get the error:
"Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
Error: Can't open display: :0.0
setting for csh as root: setenv DISPLAY xenon:0.0 then gives the error message:
_XTransSocketINETConnect() can't get address for xenon:6000: hostname nor server name provided,
or not known
Error: Can't open display xenon:0.0
I seem to remember never being able to su in xterm and be able to run any programs no matter what
combination of settings I have used. I also think that the error messages might have been different
but I am starting to lose track of the error messages for combinations of settings for hostname,
DISPLAY, etc. I probably need to start putting all of this down on paper so I can find any patterns.
Rob.
