Script to start ES or Desktop on boot

Frazatto

@mitu said in Script to start ES or Desktop on boot:

Are you running this from rc.local or from autostart.sh ?

I already have a similar code running in rc.local to switch between lcd or hdmi on the fly and it has been working as intended.
Now I'm trying to choose ES or Desktop depending if HDMI cable is connected or not.

My previous idea won't work.....rc.local is not the last script to run during boot and trying to bring up a GUI before end of boot is probably a bad idea.....hum.....

One thing I noticed, autostart.sh doesn't have the #!/bin/bash header, is it really a bash script??? Or is it just a flag for what ever ES is doing to start after boot?

It's a Bash script. This is how EmulationStation is started automatically on boot.

@mitu Okkk....I researched a little more and tried this script:

#if HDMI connected, go to desktop
video="$(tvservice -s)"

if [[ $video =~ "HDMI" ]];
then
  startx
else
  emulationstation #auto
fi

And I tested just with strings and bash before truing to boot and I'm 100% sure it does what I expect.
But black screen is confirmed if you try to startx inside autostart.sh!!!!!

I will have to find another way of doing this.

BuZz

@Frazatto do you have splash screen enabled? Try disabling

Frazatto

@BuZz all splash screens are disabled.

Some more info...
Adding & after startx let the terminal keep running and showed me the real errors occurring.
You will get an permission denied as tty1 is occupied by the original user, Xorg can't start since the display is already in use and I don't want to run Desktop as root all the time and adding Pi to tty group only cascade into other access errors.

So I think this is a definitive answer that it is not possible to startx conveniently on ES autostart.sh

No, it's not - I actually tested and it works. I'm on the latest RetroPie version (Raspbian Buster) and I have no problem starting the desktop from autostart.sh.

Maybe you should give more details about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

Frazatto

That is unexpected.......
Yes I did read that, didn't seam pertinent till now.

raspberry pi 3B+
Raspbian Buster
Retropie 4.6.2

mitu

Try this - disable any programs in autostart.sh. On boot, you should be presented with a command line prompt. Run startx from there and see if it works. If it doesn't, post the X.org log file to pastebin.com, from $HOME/.local/share/xorg/.

Frazatto

@mitu now I'm just confused :D

If I try what you asked, it works just fine.
So I went ahead and tried just startx & in autostart.sh and I get the same error.
This is the log you asked for when the desktop fails to start:
(the line about xf86OpenConsole used to be an access error to tty1 that I "fixed")

The error shows you're trying to run X on the 2nd text console, not the first. When running on the 1st one, it should show something like

[420164.968] (++) using VT number 1

Do you have other configuration added to the default image ? Did you add something to /boot/cmdline.txt ?

Frazatto

@mitu manually? Never touched this file before.
This is it's content:

dwc_otg.lpm_enable=0 console=tty1 console=ttyAMA0,115200 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait fbcon=map:10 fbcon=font:ProFont6x11 logo.nologo

mitu

That's strange, doesn't look like a standard cmdline.ext. Did you install from a Raspbian Lite image or from a RetroPie image ?

Frazatto

@mitu
https://www.raspberrypi.org/downloads/raspberry-pi-os/
"Raspberry Pi OS (32-bit) with desktop and recommended software"
Than Retropie flowing the GIT guide.

How does your look like?
What does this file do?

mitu

@Frazatto Not sure if that file is the culprit, but I've seen configuration when the default tty was modified via that file. Sorry, I have no ideas why it's not working, I just tested on a stock RetroPie install and couldn't get any errors.

Frazatto

@mitu don't worry, you tried to the very end and I thank you!
On the Raspberry forum nobody even bothered to answer me :P

That's probably because your problem is specific to the RetroPie auto-start configuration and not something Raspbian/Raspberry Pi related.

Frazatto

Just for future reference, I was messing around with this problem again and it just worked now........

So to recap, if you want to change between X and EmulationStation depending on what output is connected, change /opt/retropie/configs/all/autostart.sh to something like the code below and it should work.

#if HDMI connected, go to desktop
video="$(tvservice -s)"

if [[ $video =~ "HDMI" ]];
then
startx
else
emulationstation #auto
fi

I believe my Pi had some inconsistency in which user had ownership over the display, I manually set up ES and Rapibian to start on cmd, than in raspconfig set it to start X and lastly changed it back to ES to start by default. (yes, sounds complicated, but it was an accident really)

After that, the code snippet should work as intended.

Sorry to resurrect this interesting topic so much later. I came to it after looking for a script that allows us to select in a menu at the start if we want to start emulationstation or the desktop. I know that it's not exactly the same as what was discussed in this thread but it's very related. I've ended up making a custom script modifying /opt/retropie/configs/all/autostart.sh, and since I think it might be useful to someone, I'll leave it here for reference (this is the new content of that autostart.sh file):

## Get WT Sizes
WT_HEIGHT=18
WT_WIDTH=$(tput cols)
if [ -z "$WT_WIDTH" ] || [ "$WT_WIDTH" -lt 60 ]; then
  WT_WIDTH=80
fi
if [ "$WT_WIDTH" -gt 178 ]; then
  WT_WIDTH=120
fi
WT_MENU_HEIGHT=$(($WT_HEIGHT-7))

## Get Architecture
ARCH=$(dpkg --print-architecture)

## Dialog Menu
if [ "$ARCH" = "armhf" ] || [ "$ARCH" = "arm64" ] ; then
  sw=`DIALOG_ERROR=5 DIALOG_ESC=1 dialog --timeout 6 --no-cancel --title "Raspberry Pi Startup Selection Tool" --backtitle "$(cat /proc/device-tree/model)" \
    --menu "Startup Options" $WT_HEIGHT $WT_WIDTH $WT_MENU_HEIGHT \
    "1 EmulationStation" "Front-end of RetroPie Project" \
    "2 Desktop" "Raspbian PIXEL Desktop Enviroment" \
    "3 Console" "Abort auto-start and remain in console" \
    3>&1 1>&2 2>&3`
else
  sw=`DIALOG_ERROR=5 DIALOG_ESC=1 dialog --timeout 6 --no-cancel --title "Raspberry Pi Startup Selection Tool" \
    --menu "Startup Options" $WT_HEIGHT $WT_WIDTH $WT_MENU_HEIGHT \
    "1 EmulationStation" "Front-end of RetroPie Project" \
    "2 Desktop" "Raspbian PIXEL Desktop Enviroment" \
    "3 Console" "Abort auto-start and remain in console" \
    3>&1 1>&2 2>&3`
fi
rc=$?
#reset  #no needed
clear
source $HOME/.bashrc
case $rc in
  0)
    case "$sw" in
      "1 EmulationStation")
        emulationstation ;;
      "2 Desktop")
        startx ;;
      "3 Console")
        echo "" ;;
      *)
        emulationstation ;;
    esac;;
  1)
    emulationstation ;;
  5)
    emulationstation ;;
  *)
    emulationstation ;;
esac

This is what it looks like:

autostart_retropie_screenshot

It's set to run emulationstation by default. A timeout of 6 seconds is established, so if the user does not press any key for 6 seconds, the default option (emulationstation) is executed. I've used dialog for the menu instead of whiptailonly because this last doesn't have the --timeout option, and although you can achieve a similar effect with other tricks it's a bit more complicated, both should work fine either way.
