In my experiments with Unity & Gnome I ended up just installing a different Desktop Environment. Mate, Xfce or LXDE are all easy to install and all work well with X2GO.
If you are using ubuntu xfce -> $ sudo apt-get install xubuntu-desktop lxde -> $ sudo apt-get install lubuntu-desktop mate which is gnome2 based -> follow this: http://www.ubuntu-news.net/2013/11/13/install-mate-desktop-1-6-with-mintmenu...
I would assume these work the same on debian
