Just to clarify: 1) Do not install the driver unless you want to use it. Uninstalling the driver will not break your system. By design a driver will be enabled if you install it. We keep an option to disable the driver but that's only to be used by gpu-manager (which is part of ubuntu-drivers-common), in order to support hybrid graphics. That is not meant to be disabled manually.
2) Optimus is supported by the NVIDIA driver. @teo1978 feel free to file a separate bug report about the external screen issue. 3) Optimus seems to fail with 340 on some systems, and even with 346 on others. We moved from the "modesetting" driver (which NVIDIA recommend but it's not the only driver that works) to "intel" because some systems didn't work (either at all or correctly). On such systems using the modesetting driver is the only solution.

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 breaks/replaces for the nvidia-uvm package.
