Isn't it supposed to do this?

There is no debconf assisted way to create a working config (that is
going to break in 1000 ways if we allow people to use nvidia-xconfig or
nvidia-settings), so there is no cleanup support either. Patches welcome :-)
Just a reminder for people installing/uninstalling that they need to do
something more to enable/disable the driver. And possibilities to
disable these checks via preseeding.

... which has well defined dependencies, the templates are shipped in
-support (so there is only one copy to maintain), but used from
xserver-xorg-video-nvidia(-legacy*) which depend on -support

n-k-c (which reaches back to ancient history) does not use debconf at all

We could say "the best option" instead of "the only option" and leave it
to the user to figure out alternatives.

/etc/modprobe.d/nvidia-kernel-common.conf: blacklist nouveau

Patches welcome :-)
