I did :)
I have since discovered it is an Intel/XOrg problem. DRI is not
being enabled on my machine because the Shadow buffer is on in X.
The solution is to disable the shadow buffer, and so DRI will get
enabled. That however means the GPU is more susceptible to lockups,
which I have experienced in the past.
Strange that Ubuntu Maverick does not suffer from this problem
Maybe time to buy a good Linux-supported video card!!
Thanks to all who had suggestions
