The reason I'm being "vague" is that I think it was under openSuse's 12.1 that it last worked. What seemed to change -- I'm not sure on the timing was a complete reconfig of the configuration files into rc-style, numbered run scripts in /etc/X11/xorg.conf.d. I'm wondering if Mesa switched away from using 'xlib-glx' in that time frame and to using the the "dri-modules" around then -- and wondering if that might be related. Can Mesa be run over a remote X connection -- or how does one set up the server side? It seems it tries to load 'swrast' and fails.

Glx is picking up the type of GLX supported on the remote card -- and correctly detecting my Nvidia based graphics card. So ... the open suse people claim that might be the problem and that MesaGL might not work with Nividia's GLX on windows using cygwin. (!?) So how can I get it to work? Ideas?
