Hi,
just for my interest, what exactly is the problem when trying to install the
proprietary nvidia drivers?

Hi Jay,
Interesting. Before installing Fedora 17, I used Ubuntu 12.04 but had a
permanent resolution problem when I installed the NVIDIA drivers. I haven't
tried that trick with BIOS though. I will give it a shot in the near future.
Thanks,
Thomas

Hi Thomas,
I we are running 2 laptops using Ubuntu, one with a 540M and the other with
a 640M. To get around the driver issues associated with the "Optimus"
technology I had to go into the BIOS at start-up and change the graphics
card option to "Discrete" . This means that the system no longer uses the
on-board Intel HD graphics chip and runs entirely on the nVidia GPU, which
solved our problems. From my understanding nVidia are in the process of
deriving a solution for using Optimus in a Linux environment, but until then
the only options I know of are independent solutions which I've found cause
problems when running some programs which use CUDA extensions.
So far I have found no real problems with running the systems on the nVidia
GPUs permanently, the systems are more stable but there is a minor drop in
battery time.
Cheers,
Jay
