[Benjamin <712052@xxxxxxxxxxxxxxxxxx>]

FYI, before calling gtk_init fbconfigs are found, after calling gtk_init
no configs are found anymore. So the problems are somewhere in the depth
of gtk. Heavily unknown terrain for me. I think I have to live without
OpenGL support :-(.

  cairo-dock states that I can't use OpenGL. Curios, since glxinfo says

  doubleBufferAttributes[16] is set to None (old value is
  GLX_STENCIL_SIZE). After taking a look at this array, i think it must
