Dear forum,

I'm trying to move a program that uses JOGL on Mesa's software renderer from a system running Debian 6.0 to Debian 7.0, and suddenly JOGL cannot initialize any longer. I cannot quite seem to figure out why, though, so any help would be helpful.

At the obvious level, I get this exception: GLException: javax.media.opengl.GLException: Profile GL_DEFAULT is not available on null, but: []

To try and get to the root with that problem, I ran the main function in com.jogamp.newt.opengl.GLWindow for its debug output, and it says the following:

javax.media.opengl.GLException: X11GLXDrawableFactory - Could not initialize shared resources for :6

This would seem to be the actual problem, but I don't see why glXGetFBConfig would start to fail just because I'm running a newer Debian version. The glxinfo program can list GLXFBConfigs properly:

6 GLXFBConfigs:
    visual  x   bf lv rg d st  colorbuffer  sr ax dp st accumbuffer  ms  cav
  id dep cl sp  sz l  ci b ro  r  g  b  a F gb bf th cl  r  g  b  a ns b eat

0x026  8 sg  0   8  0 r  y .   2  3  3  0 .  .  0 16  8 16 16 16 16  0 0 None

And I can only imagine it uses the same function to get them, no?
