@k3001993 One further thing, I found by changing Terminal=false to true, then a terminal window will popup asking for a password, enter the password and it works. So only conclusion I can draw is that it must be permissions related.

So I've come up with my own solution. I changed /opt/retropie/config/scummvm/emulators.cfg default entry to point to a custom launcher script of my own: #!/bin/bash game="$1" pushd "/home/pi/RetroPie/roms/scummvm" >/dev/null /opt/retropie/emulators/scummvm/bin/scummvm --fullscreen --joystick=0 --extrapath="/opt/retropie/emulators/scummvm/extra" -p "/home/pi/RetroPie/roms/scummvm/$game.svm" --auto-detect popd >/dev/null And then I just make sure the scummvm rom directories end in ".svm". This custom script utilizes the --auto-detect flag so that scummvm figures out what game it is. So far in my testing it works. Obviously this launcher script could use some work, but it's doing the job so far.

@warpath0007 Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

Yes, you rock ! it works with this change indeed in the file /opt/retropie/supplementary/runcommand/runcommand.sh changed the line : id="$(echo "$line" | awk '{ print $2 }' | grep "([0-9]\{1,\}x[0-9]\{1,\})")" with this line id="$(echo "$line" | awk '{ print $2 }' | grep -o "(0x[a-f0-9]\{1,\})")" And the line : mode_id[1]="$($XRANDR --verbose | grep " connected" | grep -o "([0-9]\{1,\}x[0-9]\{1,\})")" with this line mode_id[1]="$($XRANDR --verbose | grep " connected" | grep -o "(0x[a-f0-9]\{1,\})")" Now the video mode selection is working great Many thanks

Had the same issue on Lubuntu 20.04, the symbolic link was missing for /usr/bin/python sudo ln -s /usr/bin/python2 /usr/bin/python

Just to confirm I had email confirmation that the change was merged into master, so post-update I tested again anyway and all works fine. Thanks for sorting this so quickly. Cheers

@RunsOnRum No, but you can create your autostart script to start Kodi first, then start EmulationStation - 2 lines instead of one.

Here is a final snippet "May 03 12:11:25 lvl3: UIModeController::logInput( Xbox 360 Wireless Receiver (XBOX) ):Button 0, isMappedTo= a, , value=1 May 03 12:11:25 lvl2: req sound [video.launch] May 03 12:11:25 lvl2: (missing) May 03 12:11:26 lvl2: Attempting to launch game... " So no errors..... But I have managed to find a fix. I'm also using the gtx970 as my sound card. if I disable this retropie works fine. Guess this will just be one of these really odd bugs that only effects me :) Thank you for your time

thanks that worked fine :)

thanks for your help mega man

@x3rl did you find any solution? I also have the ystek micreal usb gamepad, left and right is also not working out of the box. Any hint would be great.

If editing files around is not something you're familiar, then my suggestion is to find a system with a bit more performance and has the righ GPU. Even if you'd manage to get EmulationStation working, other programs/emulators might have similar requirements and you'd be struggling to make it work.

@hawkes_84 we only support the rpi4 on Raspbian

You haven't added any details about your system - as detailed in https://retropie.org.uk/forum/topic/3/read-this-first. To get a detailed log file from the emulator, enable debug logging from Runcommand launch menu when launching the game, then exit the emulator and post the contents of the log file (/dev/shm/runcommand.log) on pastebin.com.

@filippoaceto said in Install retropie on ubuntu: Is there any way to install retropie on pi4 with ubuntu? No, on a Raspberry Pi only Raspbian is supported.

I'm going to assume I post in the "help and support" thread, if there's a better place please let me know. Thanks again all.
