Hi Mike,
Initially i started to develop X2Go KDrive based on source code of xorg-server-1.19.2. I made some patches to port it for some older versions used by SLES12SP1 and Leap42.3. I didn't try it yet with newer versions of XOrg, however I think it should not be a big deal. Looking on the log you provided, I could guess that the problem is somewhere in the XRandr handling. But I would need to take a closer look to be sure.
Regards Alex

Hi All,
I'm glad to introduce you a new X2Go feature - X2Go KDrive. X2Go KDrive is a new X-Server for X2Go, similar to Xephyr. It's based on the recent X.Org code and can run modern desktops and apps, like Gnome-3 and KDE-5. I uploaded some sources to our git repository. It's not a release or even testing version, just kind of review at the moment. We don't have any build system for it yet. However I wrote some instructions, which could help you to build it.
check our wiki page if you need more information:

Stefan managed to get some funding for me to work on wrapping up X2Go KDrive (Agent + Client) as DEB packages.
I have committed quite some stuff to the repos, more to come the coming week. Please review. Especially, I prepared native builds against the DEB package xserver-xorg-source.
I also ported the nx-libs test scripts. With X2Go Client and also with the "on-localhost" testscript, I get this segfault:
However, I currently get this SegFault Traceback when initiating a connection:
