Damn, ensuring that there are proper dependencies for all the NVIDIA
packages breaks (well, sort of breaks) the upgrade in case
nvidia-opencl-icd was installed in wheezy for no good reason ...
I've now prepared two changes in SVN (n-g-d branches/jessie):
nvidia-graphics-drivers (340.46-6) UNRELEASED; urgency=medium
* nvidia-kernel-dkms: Switch to Recommends: nvidia-driver | libcuda1
to break the chain libcuda1 -> nvidia-kernel-dkms -> nvidia-driver.
* nvidia-opencl-icd: Downgrade the Depends: libcuda1 to Suggests. This
should avoid pulling in too many NVIDIA packages on wheezy -> jessie
upgrades of systems that have no NVIDIA hardware, but nvidia-opencl-icd
installed nevertheless. (Closes: #769072, #770588, #769191)
In upgrade tests in minimal wheezy chroots with nvidia-opencl-icd
installed that seemed to work and did no longer pull nvidia-driver into
the system.
I don't know how seriously the missing libcuda1 breaks
nvidia-opencl-icd. I can see that this is being dlopen()ed, but at least
clinfo still reports something about the GPU. I don't have a better
testcase right now, suggestions welcome.
A more proper solution could be to rename nvidia-opencl-icd to e.g.
nvidia-icd and add an empty nvidia-opencl-icd package that only
Suggests: nvidia-icd. That would prevent inadvertent "users" of
nvidia-opencl-icd from getting anything new from the nvidia stack but
everyone who really wants to use nvidia-icd would have to install it
manually.
(but we could Recommend it from nvidia-opencl-dev
(src:nvidia-cuda-toolkit)).
