Kubuntu driver manager fails to install nvidia-prime on hybrid systems and that makes system unusable for unexperienced users

[Serhiy]

Ignoring the fact that only nvidia-340 drivers were suggested when 390 is available, with a completely fresh install after using Kubuntu driver manager system does not show GUI on the next boot because NVIDIA drivers cannot work without nvidia-prime on hybrid systems.

The driver manager simply installs the nvidia driver/meta package for the compatible selected driver. If prime should be a dependency of that, then is really an issue with that package.

It's not needed for everyone, just for laptops with hybrid nvidia graphics. With current behavior some perfectly reasonable user actions render system unusable without CLI knowledge. IMO it's exactly driver managers' problem and it should not just install a package but make sure drivers are correctly installed for this system.
