[Mne_analysis] Unable to open mne_analyze

[Manfred G Kitzbichler]

Hi Conrad,

I just logged on to "Wittgenstein", the machine that seems to have the 
issues, and started mne_analyze without problems. mne_opengl_test runs 
fine too. If you are really connected locally, there must be an issue 
with the X-server setup. I would suggest to run glxinfo, glxgears, and 
check your /etc/xorg.conf
