Package: x2goclient

Version: 4.1.0.0


When I connect to a linux x2go server from the windows client, it brings up the "connecting" dialog, but both the x2go client and VcXsrv Server then crash without error.   The previous version of x2goclient did not have this issue.  In fact, if I downgrade to v4.0.5.2, everything starts working again.  I have another Windows PC with the same configuration connecting to the same server and it does not have this issue with v4.1.0.0.


My configuration:


Client OS: Windows 10

Server OS: ArchLinux (x2goserver v4.1.0.0)


VcXsrv settings:

-rootless -notrayicon -clipboard -keyhook

start x-server on x2goclient start


Session prefs:

Try auto login via SSH Agent (using pagaent provided by x2goclient)


Session Type - Custom Desktop

Command - /usr/bin/startxfce4


Input/Output - Xinerama disabled


Media & Shared Folders - SSH port forwarding disabled


Here's the output log in debug mode:
