Yes. It is able to boot, but graphics won't function if I disable switchable graphics. > I'm not shocked this doesn't work. nvidia support is quite limited.

I do the same thing, I just use the intel graphics and let the nvidia card sit on my computer, but for some reason beta won't work even with that. 6.8-stable works fine.
