I recently upgraded from 10.04 LTS to 11.10. I use this machine remotely via NoMachine during the day and had some issues with Unity so I switched the desktop to Gnome while at home last evening. It worked fine, but when I'm using NoMachine the applications menu is missing from the top toolbar.
I would like to switch it back to Unity, but it logs directly into the desktop without being able to set the desktop option.
I'm guessing the desktop setting is contained in a file and I can edit it via ssh shell and Vim, but have no clue where the file is or what it's called.
