With the exception of eskimo.com which is an old Sparc box with 64MB running SunOS 4.1.4, I checked all shell servers to make sure x2go and the xfce Desktop were working properly.

     I found several machines where x2go was not going full screen because of the wrong version of xrandr and corrected those.  They were Fedora, Scientific7, and OpenSuse.

     I found several machines with broken installations of xfce and corrected those, these were centos7, debian, and mxlinux.
