When I installed this certain software on OpenSUSE 11, I got the
following error:

Application initialization failed: no display name and no $DISPLAY
environment variable

And when I run the "env" command, I get the following value for
DISPLAY:

DISPLAY=:0.0

My default shell is set as /bin/csh


What do I need to do to make my display environment value to be
something like this:

DISPLAY=linux-u4f0.site:0.0


Thanks.

Sorry, please disregard the last post. It's incorrect. Here's the
correct post:



When I installed this certain software on OpenSUSE 11, I got the
following error:

Application initialization failed: no display name and no $DISPLAY
environment variable

My default shell is set as /bin/csh


What caused this problem, and how can I fix it? Thanks.

You should be a bit more specific of what you're trying to achieve. If
you aren't trying to run an X application remotely (from another PC),
then your current DISPLAY var is just fine. If you're trying to run a
graphical program as root from the terminal (let's call the program
"foo"), then try:

kdesu foo

or if that doesn't work:

sudo foo

But we need more details to know what's going on.

Yes, I'm installing a CAD software, and whenever I have superuser
privileges, I keep getting this error:

Application initialization failed: no display name and no $DISPLAY
environment variable


And if I don't have superuser privileges, then, the software runs, but
later on, it tells me I don't have superuser privileges, and it stops.

Yes, I'm trying to run a graphical program as root from the terminal.

The problem is a certain thing that goes wrong. The obvious way is to
correct certain things.

Well, not a very helpful comment. Perhaps the following helps:
1. (already mentioned in the first reply) try to run your CAD software as
sudo / kdesu
2. type
xhost +localhost and try again. Depending on some configuration settings
this sometimes still doesn't work and you'll see again the errors like 'no
display name' etc. try xhost local:root. su as root and start your program.

Try merging Xauthority file first:
> /usr/bin/sudo /usr/bin/xauth -f /root/.Xauthority merge .Xauthority

Now you can run gui as root

It wasn't intended as one. The GP does not give very much information
and when it is given, the information is spread all over the place.

He tells us "When I installed this certain software" and then _I_ have
to search for what he installed? I don't think so.

If he doesn't clean up his act, I will plonk him, although he probably
doesn't care.
