This isn't really related to runit, but well...

You'll have to install the prime-run script. Since you have the nvidia proprietary driver installed:

- If you have Arch repos enabled, run pacman -S nvidia-prime.

If you don't, here's manual installation procedure (since our package maintainers haven't ported nvidia-prime yet):
- Download Arch's prime-run script and copy it as root to /usr/local/bin and make it executable. A terminal one-liner for that:
Code: [Select]
wget https://raw.githubusercontent.com/archlinux/svntogit-packages/master/nvidia-prime/trunk/prime-run && sudo install -Dvm755 {,/usr/local/bin/}prime-run

After that, just run prime-run supertuxkart (or other game, or put prime-run %command% on Steam launch options.

I have similar dual graphics, too, and I use nvidia Optimus for that. It works well in Artix. All I need is to run
Code: [Select]
primusrun <program>
or
Code: [Select]
optirun <program>
if I need a program to be run on the Nvidia card. bbswitch-dkms kernel module is a very handy thing in this case, it keeps Nvidia card turned off while it's not used, and turns it on only when it's in use. This keeps my laptop cool.
