The problem still persists in Debian wheezy.

When I open a remote X2Go session, in windowed desktop mode, I can  
resize the desktop session window but the GNOME3 session inside that  
desktop session window does not resize its elements.

The problem now seems to be that the _NET_DESKTOP_GEOMETRY(CARDINAL) =  
<width>, <height> does not get updated if the bearing NX/X-Server  
screen resizes.

If I run a similar test with MATE as desktop shell, I can resize the  
X2Go desktop session's window and all MATE desktop elements resize as  
needed to fit the new desktop size. Whenever such a resize event  
occurs, the _NET_DESKTOP_GEOMETRY(CARDINAL) = <width>, <height> gets  
updated with the new windowed X2Go desktop session geometry.

The problem in Debian testing is different.

The NX/X11 code provides a very old GLX extension (v6 IIRC) which is  
not recent enough for GNOMEv3 (>= 3.8 IMHO) to be usable inside an  
X2Go session.

There are people that fiddle with setting up a GNOME3 session via  
calling the GNOME desktops components individually via a script (so  
omitting the actual gnome-session call on session startup), but that  
is still very hacky not I consider that only as a work around for X2Go  
and not recommendable.

Greets,
Mike
