[Benjamin <712052@xxxxxxxxxxxxxxxxxx>]

I've tried both, cairo_dock_get_Xdisplay and XOpenDisplay and both
method doesn't change anything. Cairo-Dock still refuses using OpenGL
since it cannot find suitable fbconfigs. However, my test program finds
fbconfigs the second attempt. Very strange! There seems to be something
special to the cairo-dock code.

  cairo-dock states that I can't use OpenGL. Curios, since glxinfo says
  I have (Intel Ironlake). After some investigation I found a peace of
  code in cairo-dock-opengl.c (line 173) where
  doubleBufferAttributes[16] is set to None (old value is
  GLX_STENCIL_SIZE). After taking a look at this array, i think it must
