I have nightly builds installed, in part becuase of xrandr compatibility
issues with the stable version and in part to help with the debugging process.
Today:
2018-02-23 14:18:00 status installed x2goserver-x2goagent:amd64
4.1.0.1-0~1578~ubuntu17.10.1
2018-02-23 14:18:31 status
The stable build of x2go presently works on Zorin except xrandr version
issues but the Nightly Builds does not. Nightly builds nxagent core dumps
when the session tries to start. Got to go now but will provide more details,
try to get a backtrace if I can, later when I get back.
I spaced, sorry, this is installed on Ubuntu 17.10 both client and
server. Also virt-manager does not work properly over x2go, using the
resize to virt option sizes to 600x800 instead of the virtual display size.
