Hello François,

Thanks for sharing your view.

In my opinion that would not be desirable, because as far as I
understand the toolkit can be used to just build the applications, and
it should be entirely possible to do so on a headless machine
designated as a build server with no graphics stack installed. If we
added a dependency on the driver, this would no longer be possible,
and the toolkit would then depend on the whole X stack.

I think it's good that there is a clear separation between the "build"
stack and the "runtime" stack, as it is often the case.

The toolkit dependency chain already has a "suggests" on the
nvidia-driver package (there might even be a "recommends" along the
way, can't remember), and on top of that the Nvidia documentation
makes clear that the driver is required to run the programs.

In my opinion, this should be enough.

Vincent, Graham, Andreas, thoughts?

Kind regards,
Luca Boccassi
