I spent some more time playing with this and it appears that DRI2 is
enabled on the Intel driver. I have marked the driver as inactive on
Layout0. It appears to me that everything is configured correctly and
that DRI is enabled. I have atteched a copy of xorg log.

Any idea what this assertion means?
