no new emacs window when ssh'ed

jakeslush · 01-25-2007, 01:34 PM

I just installed openSuSE 10.2 on my laptop and setup emacs from what was already included. When I use emacs from my machine, it pops up in a new window just fine. I then ssh'ed into my school network and used something similar to: emacs test.cpp &

The shell thinks it is opening a new window using emacs but nothing happens. I hit enter and it suspends what never was open. I dont know how to get that window to open. Can anyone help me out with this issue?

You need to export the display to your machine. On the remote machine:

Code:

export DIPLAY=your.ip:0.0

I typed the command you specified above and it does not recognize the export command. Any suggestions?

Sorry.. I spelled DISPLAY wrong. For a bash shell, it should be:

Code:

export DISPLAY=your.ip:0.0

If that doesn't work, try

Code:

setenv DISPLAY your.ip:0.0

You could also have ssh forward your display

Code:

ssh +x server.ip

I've done what you said and the following happens,

Code:

linux2[3]% export DISPLAY=130.85.24.89:0.0
export: Command not found.
linux2[4]% setenv DISPLAY 130.85.24.89:0.0
linux2[5]% emacs test.cpp &
[1] 5276
linux2[6]% emacs: Cannot connect to X server 130.85.24.89:0.0.
Check the DISPLAY environment variable or use `-d'.
Also use the `xhost' program to verify that it is set to permit
connections from your machine.

I wasn't sure about the last one so I didn't do that. I'm not too familiar with linux so I couldn't locate the ip of my server.

I hope its not just user error....

ssh -X <ip address>

I think that this should solve your problem.
