Setting up my Hybrid graphics Laptop with Archcraft Linux

Setting up hybrid graphics linux is generally painful with the current state of Nvidia support. If you can avoid getting an Nvidia GPU based laptop if you plan to use Linux. I use a distro called Archcraft and had some issues specific to my setup (distro/hardware)

The hardware I am installing this on is a TongFang GM6TG7W (aka Wootbook Extreme IV). It has an Intel iGPU and an Nvidia 3070 Max-Q dGPU.

This is all you really need to know in order to make Action Mailbox work in development.

1. Fire up ngrok http 3000 and make note of your subdomain for steps 3 and 8.
2. Create a Mailgun account because they offer sandbox addresses; grab your domain from the Dashboard.
3. Go into Receiving and create a catch-all route pointing to: https://XXX.ngrok.io/rails/action_mailbox/mailgun/inbound_emails/mime
4. Add your Mailgun API key to your credentials:

action_mailbox:
 mailgun_api_key: API KEY HERE
