Thanks for all the reports. We have tracked this down to a problem with the kernel's VGA arbiter trying to move VGA ownership to a GPU that hasn't POSTed. We're working with the developers of the VGA arbiter to get this fixed in the kernel.
In the meantime, we have a patch which works around the issue by preventing the VGA arbiter from moving VGA ownership away from the default device. It is attached as "NVIDIA_kernel-195.36.24-682377.diff.txt".
You can apply the patch by downloading the latest installer from http://www.nvidia.com/object/linux-d...195.36.24.html
(32-bit) or http://www.nvidia.com/object/linux-d...195.36.24.html
(64-bit) and running the installer with the "--apply-patch /path/to/patch.diff" option. This will create a patched installer with a name ending in "-custom.run", which will install a driver with this workaround.
