I was using a previous version of OS X and used to connected to a server with an SSH console. It used to run X11 after loading my requested programs (Mathematica) on the remote server and was working properly.

Recently I upgraded my Mac to the latest version (OS X 10.8.4) and SSH is now not loading the "X" anymore. I therefore access my requested programs from the remote server.

How can I fix the problem? I downloaded an extra version of X11 and installed it, but there were connection failures in the graphical interface. It was working with properly with X11 in the previous version.

  • What version of OS X did you run before? What exactly are you doing when you connect to the remote server? Which programs do you open and what commands do you enter?

  • → slhck: the one integrated with OS X 10.7. → Alex: which X11 version did you install? Where did you install it? Could you add in your original question the typical output of: type xterm?

Make sure to install XQuarts as mentioned by oozic.

Troubleshoot the connection by logging in with verbosity.

ssh -xvvv foo@bar  

Verify that you have the DISPLAY environment variable configured in your mac. Here is what mine looks like.

env | grep DISPLAY
DISPLAY=/tmp/launch-51CsPO/org.macosforge.xquartz:0

They removed x11 support in OSX since Lion 10.7.x http://support.apple.com/kb/HT5293

They suggest you to use this: http://xquartz.macosforge.org/landing/

I used once and it was working fine (connecting to lxde remote desktop)

I suggest to reinstall the latest version of GSI-SSHTerm.

Ensure also that your client accepts the server's certificate, especially if the server is using a self-signed certificate. You may need to update your CA certificates files.
