Restore Nvidia dgpu as default.

Awhile ago I broke my nvidia graphics and I've never got it back in full working order.
No matter what I run it seems it is just being ran on my integrated graphics, is there a way to switch it back to my dgpu?
Or better yet, to toggle it when I don't need my dgpu?

Re: Restore Nvidia dgpu as default.

The official method for toggling is PRIME: https://wiki.archlinux.org/title/PRIME# … er_offload

Judging from the integrated GPU this is not yet a Turing card so you might not be able to benefit from full power management, but if you haven't negatively noticed that  by now, PRIME will generally be the best maintained option.
