[X2Go-User] XFCE terminates immediately when user is already logged in on Debian unstable

[Rainer Poisel]

Dear list,

since one of my last updates to my Debian systems x2go behaves differently:

XFCE is my primary window manager. When a user is already logged in
locally to a XFCE session it is not possible to login to the same
system using the XFCE session type in x2goclient.

These are the log messages I can see in the x2goclient log area:

8<=================
...
Info: Forwarding X11 connections to display ':0.0'.
Session: Session started at 'Sat Dec 17 21:19:46 2016'.
Info: Established X server connection.
Info: Using shared memory parameters 0/0K.
8<=================

Shortly, a black window pops up, immediately closes and this is what
is then appended to the x2goclient log area:

8<=================
Session: Terminating session at 'Sat Dec 17 21:19:48 2016'.
Session: Session terminated at 'Sat Dec 17 21:19:48 2016'.
8<=================

Using x2go works like a charm with the XFCE session type in case the
user is not logged in locally.

Any ideas or similar experiences?

Thanks for helping me out,
  Rainer
