I don't remember exactly about windows decorations, I'll try again but in any way, the result is just plain unusable so in this specific situation (aka. resuming a Published Apps session from a TCE), it would be better to block the resume and propose to close the session before opening a new one.

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.)
