Comment 2 for bug 1366284

Finally have purged all the nvidia-prime.* inside /var/lib/dpkg/info/ and /etc/init/ to be able to remove nvidia-prime package.

note: as gdm is now used due to lightdm is actually broken (but still installed), i wonder about the "start with lightdm" inside /etc/init/nvidia-prime setting; should it also propose "gdm" or/and else as a fallback ?
