Thank you.

The X Generic Event Extension (XGE) was added in libX11-1.2 and 
xorg-server-1.6 in order to support future X event types within the 
limited number of event opcodes allowed in X.[1]

Any time the client Xlib detects that the server does not support an X 
extension which the client code wants to use, it issues a similar 
warning.  For example:

$ Xnest :2 &
$ DISPLAY=:2 gvim
Xlib:  extension "RANDR" missing on display ":2.0".

That's because the Xnest server does not support the RandR extension (as 
you can see with xdpyinfo).

In your case, your remote client must be using libX11-1.2 but the 
current Cygwin 1.5 xorg-server is only 1.5.3, which does not have XGE 
support.  The good news is that the missing extension is harmless, as 
nothing actually uses XGE yet.

Cygwin 1.7, currently in beta[2] but due to go stable RSN, already ships 
with the latest server and libraries, so this message will go away 
whenever you update to 1.7.
