Unfortunately, with Fedora 24 x86_64 as X2Go server this changed: - local Xfce session blocks X2Go Xfce session of same user - X2Go Xfce session blocks local Xfce session for same user Choosing non-Xfce entry (f.e. LXDE) as X2Go and local session the connection is established and the session is started and working fine at the same time. No automatic disconnection. Problem can be reproduced with these steps: on X2Go server computer (Fedora 24 x86_64): log in to Xfce session as 'user' on X2Go client computer: - start X2Go Client and connect to X2Go server as 'user' and a Xfce session - in X2Go Client status changes to 'Running' - window for remote computer appears - some seconds later same window is closed automatically - in X2Go Client status changes to 'Finished' The X2Go Client version and operating system does not seem to matter. I could reproduce the problem with: - Windows 7 X2Go Client 4.0.5.1 2016-08-18 - Lubuntu 14.04 X2Go Client 4.0.1.1 - Mac OS X 10.10.6 with X2Go Client 4.0.5.1 Output on Fedora 24 X2Go server is: $ tail -f /home/user/.xsession-x2go-errors XSession-x2go: X session started for user at Sat Sep 10 15:09:20 CEST 2016 xfce4-session: Another session manager is already running $ sudo tail -f /var/log/messages Sep 10 15:30:51 f24e5720 systemd-logind: New session 21 of user user.

Disabling SElinux on Fedora 24 X2Go server does not make a difference: $ sudo vim /etc/selinux/config set to disabled $ sudo reboot Performing fresh installation of Fedora 24 X2Go server from scratch does not make a difference.
