Wait a minute - we are running a Display Manager in X2Go-TCE ... in the
live edition at least.
So Window decorations should be there, just no task bar.

Walid - did you change anything in your TCE setup compared to
X2Go-TCE-Live, branch "feature/openbox"?

What SHOULD happen is that X2GoClient starts up in fullscreen, but any
popup it shows (like asking for a keyfile's password, or displaying that
there's no route to host) should have window decorations. And I'd assume
that the same window manager would put window decorations around PubApp
windows once the session resumes.

(Of course, it will still be almost unusable, as there's no task bar, no
logoff button, and no menu, but I'm surprised to hear that there are no
window decorations.)
