Script to start ES or Desktop on boot

Frazatto

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

/opt/retropie/configs/all/autostart.sh

Well.....
The only thing in the file right now is
emulationstation #auto

But I already found a post from 2016 (if not mistaken) with no resolution where the OP tried that and it would just black screen. He said if you get to the autostart file, it was too late on his tests.

I will try it later anyway and let you know, thanks o/

Frazatto

@mitu
Yep, black screen.

I'm trying this code, see any errors?

#if HDMI connected, go to desktop
video="$(tvservice -s | sed "s/^.*\[\([^ ]*\) .*$/\1/" )"
if [ "$video" == "HDMI" ];
then
  startx
else
  emulationstation #auto
fi

If I save the script you posted and execute it with bash <scriptname>, I get an error

sed: -e expression #1, char 23: Unmatched ) or \)

If you execute the script manually, after boot, does it determine correctly if it should start ES or the Desktop ?

Frazatto

@mitu it works as intended in rc.local to load the lcd driver when no HDMI is detected.
Unless it is miss understanding the commas, I'm not finding any mismatch.

Maybe if I set both ES and Raspbian to load to prompt and decide with to start in rc.local, hum....seams a good idea.

I will test later, thanks o/

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

I'm just posting what I get when running the script.

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.

Frazatto

@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.

Frazatto

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.
