Bug#735049: nvidia-support: Debconf prompts are misleading for NVIDIA Optimus users

[Vincent Cheng]

Package: nvidia-support
Version: 20130816+1
Severity: important
Tags: patch

Dear Maintainer,

Installing bumblebee-nvidia (for optimus support) also pulls in the
proprietary nvidia packages, along with nvidia-support; during the
installation process, the user will see a debconf prompt saying that a
xorg.conf snippet must be used to enable the nvidia driver
(nvidia-support/create-nvidia-conf), which does not apply for nvidia
optimus users and will break glx on the user's main display if the
user blindly follows those debconf prompts.

Please consider the following patch (attached with this email) against
nvidia-support's debconf templates to address this issue.

Regards,
Vincent
