Running JOGL over cygwin/X

[Mithrandir]

I'm just playing around a little bit with our large collection of unix boxes and trying to get them all displaying on a Windows machine running the latest Cygwin/X setup. dpyinfo is telling me GLX is running and everything is hunkey doery, but when I run the JOGL apps, the capabilities chooser is complaining about no maching capabilities. Just wondering if anyone has successfully got this combo running, and, if so, what capabilities you set in order to get it to function. For reference, I've tried a SUSE/AMD, Redhat/Intel and Solaris/Sparc machines all talking to a single WinXP/SP2/GF6800GTX machine.

Edit: I've found out a little more info. glXGetConfig is returning False to the GLX_RGBA query. This causes the internal query to say that there is no valid GLCapabilities that it can represent. That in return passes a null back as the GLCapabilites object and then the capabilities chooser obviously cannot find a matching caps. I'm not seeing why it should return false, as xdpyinfo says there's lots of TrueColor visuals available (32 to be exact).
