settings to use dedicated card by default in PRIME machines

[travisghansen]

I successfully installed this on an older dell xps with the 37-470 line of drivers. The laptop runs 100% of the time powered by ac and I’m wondering what kind of configuration could be done to make the dedicated gpu the default so the desktop experience and all apps are launched running off the nvidia. Ideally gnome would be accelerated along with video players and ff/chrome etc.

Thanks!

I actually figured this out, but just a warning, setting this up is what led to #200. But, if you really want to do this:

1. Open /etc/supergfxd.conf, and change the default mode from "Hybrid" to "NvidiaNoModeset."
2. Create /etc/udev/rules.d/61-mutter-default-gpu.rules and put the line from here in it.
3. Remove /etc/modprobe.d/supergfxd.conf.
4. Reboot

I'm not sure exactly why "NvidiaNoModeset" works to switch to pure-nvidia and modeset stays on, but it does. 🤷‍♀️

And then you'll probably want to set WaylandEnable=false in /etc/gdm/custom.conf if you like a semi-functioning computer.
