Before I posted question here, I'd been hacking around for the solution for my problem, but none of them worked. Here is my situation. I had a Win7 OS before I put a Debian Squeeze on it, now I got a dual-boot. However, I tried both ways to install driver for my Nvidia Quadro 1000M card on this machine, Debian ways,
and the Nvidia driver script from its website, both yielded the same result.
"failed to initialize the nvidia graphic device, none of the screen has been configured."(From var/log/Xorg.log)
and one thing I realized was that after tweaking the linux version of Nvidia driver from above, my windows Navidia driver broke as well when I logged into windows, and I had to reinstall to get it back working again. This seemed odd because they are on different partitions and filesystems. Does it mean that I can't get two drivers on the same machine even there are for different OSs and are in different partition? Or those above solutions only worked for standalone linux machine? Sorry about my incomplete knowledge for drivers, but please help cuz I am going nuts here. Thank you ini advance.
