script or bash to exit MM and exit GUI and run a command in TTY mode

[AxLed]

Hi to all,

i am trying to extend my MM for a second purpose -> Retropie.
Therefore i need a script or bash or any way to do the following:

• exit MM (maybe exiting PM2 is also fine)
• exit the Raspian / Pixel GUI (as retropie dont run in GUI Mode)
• run the “emulationstation” command in the TTY terminal

Does anybody has hints for me to do that. For the beginning i would be also ok to run a script manual by entering the commands in terminal.

Thanks in advance.

Hi to all interested,

i testet some hours and made little progress.

There are following requirements:
Tools:

• pm2
• xdotool

Starting MagicMirror from Retropie works somehow, see the following lines:

• add a MagicMirror.sh file in the fork folder of retropie with the following code

#!/bin/bash
    echo "starting MagicMirror"
    sudo service lightdm start #to start GUI
    #pm2 stop emulationstation, final commands missing so far
    pm2 start mm #to start MagicMirror
    xdotool key Ctrl+Alt+F7 #to change to tty7 = Gui

• make this file executable

Starting Retropie from MagicMirror works somehow, see the following lines:

• editing file /opt/retropie/supplementary/runcommand/runcommand.sh, change links from tty to tty1. Make sure owner and group ist root after editing

• add a es.sh file in a folder of your choice with the following code

#!/bin/bash
echo 'starting Emulationstation/Retropie'
sudo service lightdm stop #to quit GUI
export DISPLAY=:0
emulationstation > /dev/tty1 #to execute this command in tty1 where emulationstation/retropie runs

• make this file executable
• put this file into pm2

Difficulties:
I dont know how to put two .sh files into pm2 and set one to “start” and one to “stop”, if i only would have one of the to .sh files executed at one time (one .sh is for MagicMirror, second .sh is for emulationstation/retropie)

put the first one in /home/pi/retropie/roms/ports and you can run it under ports section in ES

the closing script is a bit tricky you can use MM module that excute a terminal command to exit like this one MMM-TouchButtons and config it like that

{
  text: 'Exit MM',
  icon: 'skull',
  action: 'exec', 
  command: 'killall lightdm'
}

it should kicks you back to ES

@Ramez
Thanks for your reply, i want to have only one app (either mm or Retropie/Emulationstation) run at one time due the pi ressources.

But i will try your approach.
