I followed the great advice given to me earlier, and installed a FreeNX server on my office computer (Fedora) and NoMachine's client on my laptop (Ubuntu 11.10). This indeed works great, accept for two problems:
- All software works great, including MATLAB, but Mathematica refuses to open. It also refused to do so over X. Here's the error message:

- I can't close the session. It doesn't bug too much because I can kill it from the console or through nomachine's session administrator, but neither the close button nor
Alt-F4don't work. Maybe this means that I didn't configure everything as I should have?
