Just for the record:
Disabling my on-board graphic adapter didn't change a thing. Also the
on-board graphic adapter usually gets automatically disabled once a AGP /
PCIe GPU is inserted. This becomes visible if you watch out for the onboard
GPU via "lspci | grep VGA"
For example on the box I am currently typing on there is an on-board GPU (AMD
E-350 with ATI HD 6310) as well as an NVidia 9500GT.
lspci just reports the NVidia:
lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation G96 [GeForce 9500 GT]
(rev a1)
..and you will hardly find any hint that there is another GPU in my system.
Simply because it is not there....
