correct DISPLAY setting

mathfeel · 05-25-2006, 05:46 PM

I am trying to do x-forwarding (not ssh tunneling, which has it own problem for me) with some network computer. Before I do that, I wanted to test what's the correct DISPLAY to set to. So here's the experiment:

Code:

DISPLAY=:0.0 xclock

works, but

Code:

# xhost && DISPLAY=localhost:0.0 xclock
access control enabled, only authorized clients can connect
INET:localhost
Error: Can't open display: localhost:0.0

This obvious implies that if I set DISPLAY=(my ip address):0.0 at another computer, it will fail as well. Any idea?

xhost +localhost did you try?

Yes, that's why I ran xhost, just to show that localhost is already added to the list. Note the line

Code:

INET:localhost

Anyway:

Code:

$ echo $DISPLAY
:0
$ xclock  (xclock runs...quit xclock)
$ xhost +localhost
localhost being added to access control list
$ xhost
access control enabled, only authorized clients can connect
INET:localhost
$ DISPLAY=localhost:0 xclock
Error: Can't open display: localhost:0
