So with proprietary blobs that give you more trouble that they're worth?
Are you refusing to use the Nvidia binary drivers and/or a setup like DKMS that ensures kernel modules are rebuilt as necessary? While I respect the principle, it's a problem you're creating for yourself.
> upgrade my Kernel whenever I want to without getting a black screen with a blinking cursor on the next boot.
Really? I had very much the opposite experience.
But once we're talking about laptops, hybrid graphics etc. it quickly shows that this is not a platform Nvidia cares about.
Just anecdotal, but I never had these issues with the desktop AMD APU I had before it or Intel on board graphics on numerous laptops.
