I tried this script but it is not stable and the emulation returns to the 1st screen
#!/bin/bash
This script will run a program in fullscreen mode (no borders or
title bar etc) on a second monitor. It can used for many programs
and on either the primary or secondary monitor
#This is the executable file or path
PROGRAM='emulationstation'
This is the output of wmctrl -l for the program that we are using
NAME='emulationstation'
This is the device name of the monitor we want to display the program on
DEVICE='HDMI-1'
If you want the program to be fullscreen on your second monitor
this variable should be the width of your primary monitor
PRIMARYWIDTH=1920
Run the program , then wait a bit before carrying on
If your program doesn't load in time then try increasing this value
$PROGRAM > /dev/null 2> /dev/null & disown && sleep 3
Set the Open GL environment variables
Set the vertical blanking to on
__GL_SYNC_TO_VBLANK=1
And make sure OpenGL syncs the correct monitor
__GL_SYNC_DISPLAY_DEVICE="$DEVICE"
Do we want a screensaver
#SDL_VIDEO_ALLOW_SCREENSAVER=0
Set the dimensions of the program in the monitor
wmctrl -r "$NAME" -e '0,'$PRIMARYWIDTH',-1,-1,-1'
Maximize it
wmctrl -r "$NAME" -b toggle,fullscreen,maximized_vert
