"Can't open display" error when try to use a program remote

heande · 03-11-2005, 08:56 AM

Hello

I am using "Xandros Desktop OS Version 3 Open Circulation Edition" and when I try to open a program remote via ssh, I get error messages like this:

"remoteserver":heande:[~]> gimp

Gtk-WARNING **: cannot open display:

or when I am trying to open Mathematica:

xset: unable to open display ""
xset: unable to open display ""
xset: unable to open display ""
Can't open display

Is there anyone who know how I can solve this problem?

Use ssh -X instead (enable X-forwarding)
on the remote, type

Code:

echo $DISPLAY

to check that it is actually set (if it prints anything else than an empty line, you're fine.

start gimp.

Groetjes,
