Retropie Installation on Ubuntu Server x64 18.04.1

Panja

Awesome guide!
I'm running Ubuntu Server 18.04.2 on a NUC7i5BNK with a DualShock 4 controller.
All is running through HDMI to my 46 inch TV (1080p).

Only problem I have is with the audio.
When loading a game, when the game actually begins I hear a (pretty loud) POP sound.
Audio is ok afterwards, it's just an annoying POP when the game loads.

Also I'm seeing an error message:

lvl0: VolumeControl::init() - failed to find mixer elements!

Any ideas about this issue?

has someone the script that was posted by Piskvor. The file is not available anymore.

Hi,

Sorry for a delayed reply, I only check in every so often depending if i'm doing any work on my RetroPie build!

Actually, I do have a copy of the original script and I do still use it - I have pasted the contents here for you:
https://pastebin.com/02Rc3UFZ

Paste it into a notepad file and save it as a '.sh' file with a name of your choice.

Let's say you save it as vncssh.sh, the command to run would be "vncssh.sh pi@retropie-pc" - if the username is pi and the machine you are connecting to is retropie-pc.

If you need the file itself, I can always upload it to my google drive and share from there. The forum doesn't allow attachments, hence I can't upload it directly.

Hope this helps.

Cheers

Hi,

Not too sure about that i'm afraid, did you follow my additional tips on post #34, at the bottom is a piece about sound:
https://retropie.org.uk/forum/topic/18810/retropie-installation-on-ubuntu-server-x64-18-04-1/34

To be fair, this is more about onboard speaker vs. HDMI sound - it sounds like yours is already set correctly, but the pop is strange. But might be worth looking at. Maybe worth disabling any onboard sound in the BIOS anyway as part of any troubleshooting.

Also, if you have an up to date ES, within the sound settings, I believe my master volume is set to 50%, the audio card 'default', and the audio device 'master'. I need to check this though, that's just off the top of my head. If yours is different, perhaps change it to this and restart the box, see if it does the same after that.

I don't get the ALSA error in the terminal like you do, so it is probably indeed related to your issue.

Just saw your latest update here:

Will reply over there.

Thanks mate!

@movisman Great man! Thx1! :)

I just setup an older i7 laptop using this guide. Everything works great except one problem:

Regardless of the emulator and rom I am using, the screen will timeout after ~5-10 minutes of play. If I move the mouse or keyboard, the screen comes back on and all is fine...for another 5-10 minutes.

I think I found the same issue on git:
https://github.com/libretro/RetroArch/issues/7472#issuecomment-485452851

Does anyone have a fix for this?

bloodykean

@scales11 in terminal type "xset q" and what settings do you have?

scales11

@bloodykean, No I did not.

However, once I installed “xdg-utils” my screensaver/timeout was fixed. NOTE: xdg-utils is the Debian package that contains xdg-screensaver

I also noticed that with the install method I chose I do not have a ~/.config/retroarch/retroarch.cfg file. Could this file be somewhere else?

@scales11

Glad you fixed the issue. I must say I didn't get this problem when installing on Ubuntu Server 18.04.1 using my Samsung TV over HDMI, but I did get screen blanking after 10 minutes and I had to wake it up with a keyboard/mouse - it wouldn't wake with the controller.

I fixed this with the commands in post 38:
https://retropie.org.uk/forum/topic/18810/retropie-installation-on-ubuntu-server-x64-18-04-1/38

I also had an error saying 'xdg-screensaver not found' when exiting Retroarch from the Setup screen, but installing 'xdg-utils' (which in turn installs xdg-screensaver) clears that error. So it's worth doing that anyway if running RetroPie on Ubuntu Server which has minimal packages.

I have this on my own documentation (which I will publish at some point).

Cheers!

I think the default is here off the top of my head:
/opt/retropie/configs/all/retroarch.cfg

I'm trying to get the Plymouth working on my Intel NUC8 but at boot I only see a black screen. Sometimes I get the RetroPie logo for a brief 1 or 2 seconds.
Any one have a clue whats going on?

Panja

@movisman or maybe someone else... 😉
Everything seems to be running excellent with Ubuntu Server except Dolphin GUI menu and for instance the FPS counter are really big. This seems to be a resolution issue.

As we don’t use a normal desktop is there a way to specify the resolution used on my machine.
Dolphin seems to use the desktop res.

Just wanted to pass along my thanks for the great information that is in this thread. I have wanted to build a system that looked just like the RPi but on x86 for a while, and never got it right. These steps nailed it for me.

For anyone interested in an automated setup of the required configs, I have created a bash script that takes care of everything, and shared it on GitHub: https://github.com/MizterB/RetroPie-Setup-UbuntuServer

It does not (yet?) handle the TV resolution changes, or the VNC login, but everything else mentioned here is collected in one place. Hopefully it is useful for others. I don't know how actively I will maintain this or improve upon it - probably depends on the interest and feedback.

On that note, please give it a shot - I welcome your feedback!

@MisterB thxs, great idea. Its r un on x64?
I sugest to add a install script for music on emulationstation, and install and update video drivers, including vulkan.

Retropie BGM script:

Panja

Which emulators benefit from the Vulkan drivers?
I'm running without them and everything seems to run smooth.
But of course improvement is always good. :)

MisterB

@wmarcio - Good point, this script is technically for X64 - I have not tried it on a 32-bit install.

The code to upgrade the video drivers and install Vulkan is actually in there. I haven't 'enabled' it yet, as I haven't had a chance to test that everything still works after the upgrades. This is where adding some configurability options would be nice... But for now you can append the following to the end of the script before running it if you want:

install_latest_video_drivers
install_vulkan

I don't know anything about the music capabilities. I will look into it.

wmarcio

@MisterB thxs, i will test your script tomorrow.

johnodon

@MisterB Excellent work! I just ran the script against an Ubuntu 18.04 install (using the x64 mini iso) and everything seems to be working as expected. The only thing I had to do was install curl prior.

I'll continue to test and report back.

Has anyone had any luck running Naomi/Atomiswave ROMs (MAME .zips) on this config using lr-beetle-dc (formally lr-reicast)...specifically on an Intel GPU?
