Some boilerplate for dealing with common issues when trying to start Sway (window manager) on an NVIDIA card.

TrySwayNVIDIA.sh

#!/bin/sh

primaryGPU=/dev/dri/card0

if [[ ! -c "$primaryGPU" ]]; then
	echo "No dri card detected"
	exit 1
fi


export WLR_DRM_DEVICES=$primaryGPU

echo "Starting sway... using WLR_DRM_DEVICES=$WLR_DRM_DEVICES"

ls -lh $primaryGPU


# Why is there propaganda in a command line flag?
