RPi5 Fails to run xstart without this modification

[arretx]

After following this guide to a tee, I attempted a reboot and was met with a failure to start X.org...the error looked like this:

Cannot run in framebuffer mode. Please specify busIDs        for all framebuffer devices

I dug through some forums and found that the following solution worked.

Login to the Pi and create a file called 99-vc4.conf in the path /etc/X11/xorg.conf.d/

Add this to the file:

Section "OutputClass"
  Identifier "vc4"
  MatchDriver "vc4"
  Driver "modesetting"
  Option "PrimaryGPU" "true"
EndSection

Reboot. Home Assistant will fire right up. I also noticed that you'll need to enable the cursor the first time in order to set the username and password of the login for the Home Assistant UI.
