Dang, forgot Google Photos no longer allows for public sharing.

Here's the copy of the error notice:

GameMode ERROR: Could not connect to bus: Failed to connect to socket /tmp/dbus-IUtBLGFtPF: Connection refused
dbus[37395]: arguments to dbus_connection_unref() were incorrect, assertion "connection != NULL" failed in file ../../../dbus/dbus-connection.c line 2822.
This is normally a bug in some application using the D-bus library.

   D-bus not built with -rdynamic so unable to print a backtrace

I wonder if the reason is we start the GUI via sudo (from the RetroPie system).

Can you exit EmulationStation and run from a terminal

/opt/retropie/emulators/retroarch/bin/retroarch --verbose --menu --config /opt/retropie/configs/all/retroarch.cfg

and see if the GUI opens up ? If not, then try disabling Game Mode by adding

gamemode_enable.= "false"

to /opt/retropie/configs/al/retroarch.cfg.

RetroArch GUI does open directly from the terminal command provided.

@testudo Then temporarily you can add

gamemode_enable = "false"

to retroarch.cfg and use it for now. I'll take a look to see why this isn't working through su, as called from EmulationStation.

Do you have the gamemode package installed on your system ?

Thanks. I tried disabling the game mode by adding the provided code to the retroarch.cfg, but no success. Still get the same error.

~~I am not aware of intentionally installing the gamemode package on my system. How would I check if it is installed?~~

I do have gamemode 1.5.1-0ubuntu3.1 installed.

Check if you have the gamemode package installed:

apt show gamemode

If it shows Installed: Yes, then it's installed.

@mitu

Thanks. Confirming gamemode is installed.

mitu

Thanks for the check. I'll see how we can solve this, seems like a bug somewhere if disabling GameMode still doesn't get RetroArch starting normally (from the menu).

mitu

@testudo Can you try updating the RetroPie-Setup script ? I've added a small modification to fix the RetroArch's error when started from the RetroPie menu.

@mitu
The update to the setup script was a success! Updated the script and I am now able to access the RetroArch GUI from the EmulationStation Retropie menu.

mitu

@testudo Thanks for reporting the bug.

Thanks for figuring out and implementing the solution so quickly!
