This is why you use the bitfield stuff to tell userspace what the actual properties of the framebuffer are. (However, there are some userspace programs which ignore that information and think they know better than the kernel about how a frame buffer is organised - which is a constant pain in the butt when you have a display which isn't BGR. But that's really a userspace bug in those silly programs.) -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
