Prime functionality is built into the nvidia proprietary driver and works with nvidia optimus laptops, so is a viable option.
ATM the configuration process for Prime is manual, a bit cumbersome and definitely not newbie friendly, hence the repeated requests from many users to see if it is possible to incorporate into mhwd.
The process for optimus laptops that currently do not boot could be to get them booting first (ie video-linux with nouveau blacklisted?), then install and configure Prime.
For optimus laptops that bumblebee works on this could still be a valid choice also, and is easily installed using mhwd.
Not looking for a magic bullet, just trying to identify a way to somehow get these systems to boot, without nvidia gpu drivers loaded if need be.
Once the system is in a bootable state then manual intervention can take place to either troubleshoot bumblebee (ie acpi boot parameters), or manually configure Prime.
Nouveau is third party reverse engineered, doesn’t support recent hardware, and its performance is just terrible.
Having an mhwd option to blacklist it is not the worst idea.
Or as Linus so eloquently put it …
