Subject: Messed up session when resuming from Published Apps mode to Fullscreen desktop mode in thinclient mode

Date: Sat, 23 Sep 2017 22:25:21 +0200 (CEST)

Package: x2gothinclient 
Version: 4.1.1.0-0~1634~ubuntu16.04.1

Let's say you suspended a session in "Published Apps" mode from a local desktop (might be Linux or Windows, it doesn't matter) then try to resume it from a TCE running the client in thinclient mode.
This will work, you can resume the session but the display is completely broken : no desktop, no decorations, corrupted display and no widget to logoff so you're stuck there unless someone kills your session from the server.

It would be better to simply block the ability to resume a Published Apps session in a mode where it just can't be done such as the thinclient mode.

Regards,
Walid Moghrabi

The question is: How do we handle that?
--no-public-applications as a commandline option? We could hardcode that
into an X2Go-TCE-startup script then.

No, that should work automatically. As long as there's a window
manager on the client side everything will work fine.
 And that's easily checkable by x2goclient.

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.)

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.

I agree on that, I'd just like to know if we have a bug with the window
decorations as well. ;-)
