What I don't understand, the proposed drivers are they already implemented
in the routine update (I thought they had to be updated manually)?
Otherwise I might have had a completely different problem with the
bumblebee and nvidia drivers, solved by chance with Your approach.

> Bug description:
>   Filing this against the 340-updates version but possibly the same
>   applies to older versions, too. The nvidia source package produces two
>   individual dkms packages: nvidia-340-updates, nvidia-340-updates-uvm.
>   The problem is that the DKMS build of the nvidia-uvm module runs
>   compile steps inside the nvidia modules build directory. This is
>   violating the DKMS assumption that each module can be build
>   independently (there is no way of describing cross-modules
>   dependencies and even more important, the autoinstall step after a new
>   kernel is installed will run the modules build in parallel).
>
>   Since nvidia and nvidia-uvm are very dependent on each other the right
>   course of action seems to be to combine both sources in one DKMS
>   module that produces two kernel modules (this is supported by DKMS).
>   For the transition this resulting dkms package needs to have a
