I am having GUI selection issue, when I select command =GNOME/KDE or Unity under in configuration of Broker server in /etc/x2go/broker/x2gobroker-sessionprofiles.conf . it is now working.

Only a Blackscreen come . While without session broker I select "Connection to local Desktop " it works.

I am using Ubuntu 16.04 LTS for x2go server and below are the logs of that .
