From Greg Rivers's Xorg.0.log: [ 54.162] (==) intel(0): Depth 24, (--) framebuffer bpp 32 [ 54.221] (==) Depth 24 pixmap format is 32 bpp Indicates it is indeed a 32-bit framebuffer, so the relaxation of this requirement is moot. Depth 24 is the three out of four channels actually used for display. "Could not find a framebuffer configuration ..." is a very common error message across GL applications in case of misconfigured or incompatible OpenGL for the reason that opening the framebuffer is the first GL-related action performed; it could be a more general OpenGL problem not specific to the framebuffer.
