Are you using Unity ? GNOME ? KDE ? A session over ssh ?
I'm really no windows management and graphical environment expert, but apparently some windows managers do not set this variable.

I just tried starting the version of GRASS available on the apt repositories and got this message: awickert@dakib:~$ grass Cleaning up temporary files ... Starting GRASS ... ERROR: wxGUI does not support wxPython 3.0.0.0 yet. Error in GUI startup. If necessary, please report this error to the GRASS developers. Switching to text mode now. Hit RETURN to continue... So I think that what you are saying is that wxPython 3 somehow becomes the default / interferes with GRASS. I did: awickert@dakib:~$ sudo apt-get remove python-wxgtk3.0 and now everything works. Well, hopefully my removal of wxPython 3 doesn't break something else, so hm, is there a way to ensure that GRASS GIS always looks for wxPython 2? The idea is rather to try to solve any errors concerning wxPython 3 as it is more and more becoming the default in Linux distributions. Anna has been quite active in trying to solve any specific wxPython3 issues. On my Debian Testing system I have Python 2.7.8 and wxPython: 3.0.1.1 and I do not see your error. So it would be interesting to explore what happens on your system. What graphical environment are you running in ? What does 'echo $SESSION_MANAGER' in a terminal give you ? Moritz
