error when starting steamlink from emulationstation

rcambrj

steamlink was working on my RPi3 with Retropie, and then it stopped working.

Pi Model or other hardware: rpi3
RetroPie Version Used 4.7.19
Built From: SD made from Raspberry Pi Imager
Connected to:

HDMI TV screen
Network cable
Xbox ONE 1537 controller (USB)
Rii wireless keyboard dongle
TPLINK Bluetooth dongle
- Xbox ONE 1708 controller

Other things of note: xpadneo installed, xboxdrv and xpad uninstalled.

When I start steamlink from emulationstation, the screen shows the grey box for a while (with a note about the log location), then returns to emulationstation. If I quit emulationstation and run steamlink it starts without complaint.

This lead me to fbturbo: what is it? do I need it?

sudo apt install xserver-xorg-video-fbturbo

...et voila! It works again.

Has something changed with the install script for steamlink to cause this?

mitu

Are you starting EmulationStation from the desktop ?

rcambrj

@mitu emulationstation is starting in whatever way it starts as part of the image that Raspberry Pi Imagermakes (I've not modified this). I'm not sure what way that is, or whether it answers your question.

mitu

Nothing changed recently regarding steamlink's installation or dependencies. steamlink needs the xorg package , which doesn't install xserver-xorg-video-fbturbo - this additional package it's not needed.

Did you install anything else that would configure the fbturbo Xorg module to load ? I can't reproduce this on a Pi3 or Pi4, though the installation is not from a straight 4.7.1 image.
Can you update the OS packages and see if removing the xserver-xorg-video-fbturbo package still gives this error ?

rcambrj

@mitu thanks for your reply.

I did try updating everything with the retropie update script to no avail.

I can't think of any new packages that might have made that change. Could it be that disabling the retropie splash screen (not the RPi one) caused this? I can test this later.

mitu

@rcambrj No, the splashscreen is not in any way related to xorg or steamlink. Either way, disabling it shouldn't affect xorg.

Have you tried removing the xserver-xorg-video-fbturbo package and checking if steamlink still works ?

rcambrj

@mitu after removing this package, steamlink still works. I have no idea what happened.

Xorg.0.log no longer contains anything about Allwinner or fbturbo 🤔

I'll resurrect this if the problem returns. But for now... thanks for your help!

rcambrj

@mitu sorry, correction: after a reboot, the problem returns. xserver-xorg-video-fbturbo is still something I need to have installed.

mitu

Do you have any configuration referencing fbturbo in

/usr/share/X11/xorg.conf.d

If you remove the xserver-xorg-video-fbturbo package, does the configuration file gets also removed ?

rcambrj

With xserver-xorg-video-fbturbo installed:

mitu

There don't seem to be any other references to fbturbo or Allwinner in the remaining configuration.

Then I don't understand from where the fbturbo configuration is referenced.

Can you check if the file still exists after you remove the xserver-xorg-video-fbturb package ? If so, remove it and see if - after rebooting - you still get the error.
