We still get segfaults even after installing icewm, albeit at least we can see the desktop.

An update to mesa broke x2go server in Fedora 25 for awhile a month or so ago.

This included MATE desktop not starting, many XFCE programs seg faulting and glx not working.

However, this has been fixed with the latest mesa and libepoxy updates. Is your F25 fully updated?

These are my mesa and lbepoxy versions with working x2go server.

     Something broke in Fedora 25 and now the only window manager I can get to
work over x2go is icewm, mate will no longer start, kde will no longer start.
