For Ubuntu 15.04, we ended up splitting the libxnvctrl packages from
nvidia-settings and merging in the Debian changes.

I'd still like to do this for the next Ubuntu release (15.10) though.

I think these in particular will be useful:
07_remove_features_for_legacy.patch - allows nvidia-settings to work
with older drivers, I have tested as far back as 304.
10_legacy_vdpau.patch - allows nvidia-settings to build with libvdpau
< 0.9, nice for backports.

I'm not at all familiar with the nvidia-alternative stuff.
Is it possible to use a recent nvidia-settings with legacy drivers?
Which driver versions are we planning for stretch?

Well, those are really plugins rather than shared libraries, in other
words, they aren't shared with any other applications.
I think we should try to keep them in the nvidia-settings package, and
they won't need to go in the multiarch directories.
We could do some post-processing of nvidia-settings.substvars so we
don't end up depending on gtk2 *and* gtk3 as the Ubuntu package
currently does. :(
I have something that shows how this could work, but I think it is on
another computer.  I'll post it soon.
