I just set up an ssh server on my netbook, running Linux Mint 15. I have a program called fluxus installed on my netbook, which is basically a graphical rendering of scheme/racket code.

I ssh'ed into my netbook using another computer running Ubuntu 13.04, and I got this error:

laura@bbydhyonchord:~$ ssh -X laura@drukqs

Could this be an ssh problem, an OpenGL problem, video drivers?

Does fluxus work OK on the remote machine? Does it display properly when run from you local machine? Does it work better if you ssh -Y instead of ssh -X? Does it work if your run xhost + on the local machine before running fluxus? –  terdon Oct 5 '13 at 23:02
    
It works on the remote machine, same problem with ssh -Y, and access control was already disabled...a GUI screen does show up for a fraction of a second before closing with the error, fwiw. –  laura Oct 6 '13 at 0:38
    
Ah, it's worth a lot. That means you know it is not an X authentication error. I assume other GUI programs run OK on the remote (and display on your local)? Also, just to clarify, fluxus works on both the remote and the local machine? I would guess that the ssh connection is not fast enough for the 3D rendering you are trying to do. –  terdon Oct 6 '13 at 1:01
    
OK, please post your graphics card details (remote and local) and try running glxgears on your local machine and post the output here. –  terdon Oct 6 '13 at 1:14

This is most likely an OpenGL and/or Mesa library problem. Try installing this package on Ubuntu:

$ sudo apt-get install mesa-utils

If the library is installed you should be able to run the command glxinfo. Additionally you can double check that things are working correctly by running the glxdemo both locally and via the ssh connection.

There are other apps included that you can try too:

  • glxheads
  • glxgears

These should all run smoothly, if they don't, then your Ubuntu system's video hardware and drivers aren't up to displaying this particular application. If it's an ATI and/or NVidia graphics card then you'll likely need to use the native drivers for the card!

If they run choppy like this, then you're not optimally configured:

$ glxgears
