Separate X11 screens on dual-head Raspberry Pi
# Sets up Xorg on Raspberry Pi 3b in FKMS mode for two screens.
#
# To put the Pi into FKMS mode, add one of the following lines to /boot/config.txt:
# 1. "fake" KMS mode (exposes the proprietary vc4 firmware driver via KMS API):
# dtoverlay=vc4-fkms-v3d
# If you wanted "full" KMS mode, fully open source "vc4" driver in the Linux kernel, you
# would use `dtoverlay=vc4-kms-v3d` instead, but then the identifiers in the Driver section
# need to be different.
