Running Ubuntu 16.10

Something is setting XDG_CURRENT_DESKTOP to GNOME, and it's messing up my unity-control-center. If I run bash -x it's not being set in the output, but can still be seen by running env.

In my $HOME/.xsession-errors I see it being set to Unity, but something later must be overriding it.

How do I go about debugging this to find the culprit?

  • Still investigating myself, but now also see that I am missing DESKTOP_SESSION in the environment, and as a result gnome-session is being started with --session=<blank> – twk3 Dec 10 '16 at 7:30

Finally figured it out. There was a syntax error in an export in my $HOME/.profile (a multiline value) which for some reason now causes all set-env from gnome-session to fail. Once the bad export was removed, everything works.
