[Resolved] Dolphin controller issue / no desktop

[tommy86]

Re: Gamecube/Dolphin not recognizing controller input

As the good forums user i am, i read through all the search results and found the thread named above, which matches my issue the most, but sadly the solution doesn't fit my setup.

Which is:
Pi Model or other hardware: X86_64 PC
RetroPie Version Used: 4.7.1
Built From: https://github.com/RetroPie/RetroPie-Setup.git
Base Distro: Ubuntu Minimal
Guide used: https://wiki.learnlinux.tv/index.php/Building_a_Custom_Retrogaming_PC_with_RetroPie_and_Ubuntu_Minimal
USB Devices connected: SanDisk 32GB USB 3.0 (as / carrying the filesystem)
Controller used: Original wired Xbox 360
Error messages received: qt.qpa.screen: QXcbConnection: Could not connect to Display Could not connect to any X display
File: /opt/retropie/emulators/dolphin/bin/dolphin-emu
Emulator: Dolphin
How to replicate the problem: Follow mentioned Guide

Dolphin in RetroPie comes with the keyboard preconfigured, but a gamepad won't work out of the box. As mentioned in the thread in the headline, starting dolphin-gui in runcommand won't show the GUI as it starts the game right away. Same as dolphin does.
I'm not able to start dolphin-emu on the desktop, since i haven't installed one to keep it as minimalistic as possible. Calling ./dolphin-emu on the commandline gives me the error message from above. Any idea but to install a desktop?

On a PC, RetroPie is only supported on the desktop. Are you running EmulationStation outside of a desktop session, from the console ?

@mitu
exactly. Besides the base installation and Retropie i only installed git dialog unzip xmlstarlet lightdm openbox and ubuntu-drivers-common. Made that up for a friend of mine who is absolutely clueless when it comes to computers. The idea is "USB stick in, turn on PC = Retropie / USB stick out, turn on PC = Windows"

But i found a solution 20 minutes ago. By accident more or less TBH. I was snooping around in the file manager included in the Retropie menu, actually not knowing what i was looking for and realized that the screen looks different from what i saw on Raspberry Pi. I navigated to dolphin-emu, executed it and voilà, there it is.

Weird... Maybe someone more experienced could satisfy my curiosity and explain why this works through file manager but not through the console.
