How do I fix a "cannot open display" error when opening an X program after ssh'ing with X11 forwarding enabled?
- by Daryl Spitzer
After launching the X11 app (XQuartz 2.3.6, xorg-server 1.4.2-apple56) on my Mac (OS X 10.6.8), opening an terminal in X11 and running xhost +, I then ssh -Y to my Ubuntu 10.04 VM (running on VMware Fusion). When I run gedit .bashrc (for example), I get:
(gedit:9510): Gtk-WARNING **: cannot open display:
set | grep DISPLAY returns nothing.
But if I ssh -Y into my Ubuntu 11.04 machine, gedit .bashrc works. echo $DISPLAY returns "localhost:10.0".
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 of the two difference Ubuntu machines that would explain why one works and the other doesn't?
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.
