Big problems here, but it does work with fiddling (Jun 2017) - not sure how much of this is require;

  • First add this (and create) to your ~/.profile
export GSETTINGS_SCHEMA_DIR=/usr/share/gconf/schemas/:/usr/share/mate:/usr/share/mate:/usr/local/share/:/usr/share/:/var/lib/snapd/desktop 
export XDG_DATA_DIRS=/usr/share/gconf/schemas/:/usr/share/mate:/usr/share/mate:/usr/local/share/:/usr/share/:/var/lib/snapd/desktop
  • I then had to create a new custom session for me to log in locally and use Mate for x2go - I did this by creating a .xinitrc file, linking to .xsessions and creating a new custom file in xsessions folder
