*Still debating whether or not a full install of Ubuntu is worth the effort vs. Lakka which “just” works, for the most part with little or no configuration. RetroArch is more configurable / tweakable outside of Lakka, however there are key differences which are covered below, mostly related to the configuration of Ubuntu.
Emulators are nothing new nor is RetroArch – a ROM emulator based on libretro cores packaged in a clean & intuitive interface. I started tinkering with this application a few days ago and found it to be rather well done. I installed a Linux distro called Lakka which conveniently boots from a USB stick straight into the emulation interface. This actually works quite well – however i wanted to go a little further with it as i already have an extra machine with Ubuntu 16.04 19.04 installed. I used once again, an additional Lenovo M73 – these are great little machines! This guide similar for more recent builds of Ubuntu as well. I’ll be updating this post as I move a long with the customization of my machine. Installation is straight forward:
For simplicity (not security) optionally enable root:
1 2 3 | sudo passwd root sudo passwd -u root sudo ufw disable |
1 2 3 4 5 6 7 8 9 10 | ##testing sudo add-apt-repository ppa:libretro/testing ##stable sudo add-apt-repository ppa:libretro/stable sudo apt update sudo apt install -y retroarch libretro-* sudo apt install -y alsa-utils sudo apt install -y openssh-server sudo sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config sudo service ssh restart |
To execute the interface I have been running sudo retroarch -v- To execute the interface….on boot – create a service definition and set it to disabled. Then create a cron job to start the service at boot.
- *Without root or superuser privileges the emulator does not seem to take any type of user input
RetroArch Service Definition – this also restarts RetroArch when it crashes or on user exit; operates like a “kiosk.”
/etc/systemd/system/retroarch.service
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | [Unit] Description=Retroarch After=graphical.target ConditionKernelCommandLine=!retroarch=0 Requires=graphical.target [Service] #ExecStartPre=/bin/sleep 30 Environment=DISPLAY=:0.0 Environment=SDL_MOUSE_RELATIVE=0 Environment=FB_MULTI_BUFFER=2 Environment=HOME=/storage EnvironmentFile=-/run/libreelec/retroarch.conf ExecStartPre=-/usr/lib/retroarch/retroarch-config ExecStart=/usr/bin/retroarch KillMode=process TimeoutStopSec=10 Restart=always #Restart=on-failure RestartSec=0 StartLimitInterval=0 [Install] WantedBy=retroarch.target |
Currently I have this service set to disabled by default. It doesn’t seem to start properly due to the before and after service constraints – haven’t figured those out yet. The workaround is to have RetroArch start via a system start chron job. Need to figure out a way to make this service run last at startup, by manipulating the various service parameters / targets “wanted” – any input welcomed.
Once installed load various modules and metadata via the Online Updater menu item.
The configuration file:
1 | vi /storage/.config/retroarch/retroarch.cfg |

Important Note: Ubuntu will pause / stall the system on boot indefinately or ~5min until a network connection is detected. on Ubuntu 19.04 this behavior can be adjusted. Other versions of Ubuntu have options such as Hotplug and editing the services file – I have tried all combinations of these solutions and none seem to work with 18.04 – so 19.04 is the answer.
Prerequisites and compiling command lines for Centos 7 / RedHat – I haven’t been able to get this working … yet!

Conclusion – I’ve been able to build a console that functions as it should; combining this unit with a media server would be an interesting possibility. However, for a dedicated system it is just easier to install Lakka, it’s developed by the same team that builds RetroArch, mostly everything just works 🙂

How do you start Retroarch without the Ubuntu GUI? I’m running Ubuntu minimal on Odroid C2 (no GUI).
There are notes on this page to create a system service, which you can configure to load on system boot. Alternatively, just type retroarch from the console.
