OK; sorry about the delay -- I needed to use the machinie for a while
(at work), and then I had a weekly staff meeting....
Anyway... I've attached results of the above. For the first & last, I
did each twice -- once using the "nv" driver, and once using the
"nvidia" driver. (The middle one only got the "nv" driver.)
So the files are:
kib_0_nv
kib_0_nvidia
kib_1_nv
kib_2_nv
kib_2_nvidia
Peace,
david
