export display error cannot open display Emery, Utah

Is "halfly" a word? I have been searching all over the net to find this solution. It can use a number of transport protocols, including Unix sockets and TCP/IP sockets. User contributions on this site are licensed under the Creative Commons Attribution Share Alike 4.0 International License.

Update: As suggested by Zoredache in the comment below, I ran sudo apt-get install xbase-clients, but I continue to have the same problem. I tried export DISPLAY=localhost:10.0 while sshed into my VM and then running gedit .bashrc, but I get: (gedit:9625): Gtk-WARNING **: cannot open display: localhost:10.0 What could be different in the configuration If you only change the xserverrc file, X will nevertheless start with "-nolisten TCP". You can also simply drop me a line to say hello!.

In this case an X client application, for example xterm, reports an error Can't open display on startup, for instance xterm Xt error: Can't open display: localhost:0.0 The first thing to Possible cause #2: the X server isn't listening A DISPLAY setting is used which causes the X client application to attempt to use TCP/IP sockets rather than Unix sockets. Upon logging into KDE and did 'ps -ef | grep Xorg' , I found "-nolisten tcp" arg. This last option can open security problems.

That works for me without difficult DISPLAY stuff. Are you attempting to override the automatic setting?

Not the answer you're looking for? gdk?

Recently in some Linux distributions, X is by default configured to listen only to localhost. If firewall on the server is enables it can block X11 session. SSH (secure shell) is a de facto standard remote access mechanism that uses cryptographic techniques to secure connections against wiretapping and session hijacking. I gave you an upvote.

Most likely for remote server you X is not :0.0, but something else (usually :10.0); although your XMing is considering itself to be :0.0, PuTTY does port-forwarding magic to hide that, If port 177 (UDP) or port 6000 (TCP) are blocked you need to fix this first. At least on the new install of 10.04 that I did this morning X11Forwarding was enabled by default. When DISPLAY does not contain a hostname, e.g.

Here are a few common error messages, their probable causes, and solutions to help you on your way. With the upgrade to 12.04.1, this stopped working (coincidence?) I'd like to get this working so I can run programs from ssh. Install xbase-clients, if it isn't installed already. –Zoredache Jul 13 '11 at 18:22 I installed it but still have the same problem.
