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".
You can apply the patch by downloading the latest installer from
http://www.nvidia.com/object/linux-display-ia32-195.36.24.html (32-bit)
or http://www.nvidia.com/object/linux-display-amd64-195.36.24.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.

If you're not comfortable with applying the patch yourself, or with
working out the conflicts between the driver as installed by the NVIDIA
installer and the driver as installed by Jockey (the restricted drivers
manager) then please wait until an updated package is available through
Jockey.
