--- Comment #1 from Norman Gaywood <ngaywood at une.edu.au> ---
Same when running under x2go with Fedora 25. From:
https://bugzilla.redhat.com/show_bug.cgi?id=1427174

x2go also broken with (at least) an xfce4 desktop.

xfce4 session starts, but many programs won't start from the menus.

xterm starts from menus and we get:
> $ glxinfo
> name of display: :50.0
> Error: couldn't find RGB GLX visual or fbconfig

And things like:
> $ xfce4-terminal 
> Segmentation fault (core dumped)

> $ gnome-terminal
> Segmentation fault (core dumped)

For gnome-terminal:
