Yes, of course.

I also faced that issue in the LTSP display manager, LDM.
I fixed LDM and it correctly parses DisplayNames, it sets 
XDG_CURRENT_DESKTOP etc.

The x2go developers may or may not fix this.
One may claim it's their fault for not catching up with the new 
standards, OK.
And another may claim that new standards should have a minimum of 
backwards compatibility, like reasonable defaults when the new env vars 
are not set.

`startx` is also affected, it will be the first time in history when 
`startx` won't work.
And one may still claim that it's the xsession's scripts' fault for not 
catching up with the new standards.


But in any case, we can't claim that a broken gnome-flashback without a 
menu is not our fault.
==> IMHO, we should either have a working menu, or refuse to run and die 
with an error "required environment variables XXX are not set".
