Subject: Cannot open default display error with x2goclient

Date: Mon, 10 Oct 2016 03:35:54 +0200

Package: x2goclient

Version:  4.0.5.2


With osx, windows and linux x2goclients, i cant connect to my x2goserver.

Server version : 4.0.1.19-0~1064~ubuntu16.04.1

It prints me : Cannot open display "Default Display".

X11Fowarding is enable in sshd, and pyhoca-gui works well.

# x2goclient --debug
