[Xcb] Issues with XCB and OpenGL

[Xavier Bigand]

I am trying to make the XCB with OpenGL sample work :
http://xcb.freedesktop.org/opengl/

I am getting the following error :
X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  31 (X_GLXCreateWindow)
  Resource id in failed request:  0x2e00004
  Serial number of failed request:  26
  Current serial number in output stream:  30


I have a Mint 16 with open sources driver and an ATI card.

Does it come from the sample code or my configuration?
