I'm running into the same xrandr version issues with Mint 18 as I did
with Ubuntu 16.04.1 LTS and Fedora 24.
So I added the nightly builds and the experimental repos, purged libnx
stuff and xnxagent, and then tried to add x2goserver and x2goagent but I am getting this error:
x2goagent : Depends: nxagent (< 2:3.5.0.32-0~668~ubuntu16.04.1.1)
