Includes a systemd service file to connect the display to tmux. Copy pitft-tmux.service to /etc/systemd/system. Then run systemctl enable pitft-tmux.service and start it with systemctl start pitft-tmux.service.
Include this in your .bashrc to autorun tmux on login and relaunch if it gets disconnected.
if [[ $(tty) == "/dev/tty1" ]] && [[ -z "$TMUX" ]]; then
while true; do
tmux new-session -A -s "tty"
