Looks like on Ubuntu, unlike Debian, /etc/modprobe.d/nvidia.conf is not
installed by update-alternatives when the main driver is Mesa.
I think this makes it unsuitable to try and ship a new nvidia.conf. What
we could do instead is, if building on Ubuntu, add the remove line to
the file bumblebee already ships during postinst:
/usr/share/bumblebee/default-conf/bumblebee.conf (copied in postinst
The problem is also aliasing, since the driver's modprobe is not in
place, we'd have to refer to each driver individually, just like the
blacklisting already does.
