Hi,

The plan looks good to me!

Regarding non-glvnd, we'll have to restrict primus* to 390xx and lower
series. I don't think there are other uses of that stack.

Once the new Xorg is released and in sid, the bumblebee stack becomes
obsolete as there is finally native support for offloading - yay!
Unfortunately this has power management support only for turing-based
cards and newer.

For older cards, bumblebee+bbswitch (without primus - "none" bridge
mode) should still be useful for power management, but only with Gnome
3.34+ which will include "on-demand" XWayland (as the kernel mods have
to be loaded for the whole lifetime of the X session, thus making power
management moot). I have not tested this yet, I will do once 3.34 hits
sid.

Hopefully nvidia will make offload power management work for all cards
supported by 435xx, so that we can truly and finally retire bumblebee
and bbswitch.
