@BuZz Just a heads up that libretro-uae accepted the fix and merged it to master.

Solved?

The problem was that the pi4 has 2 "connected" outputs (given by xrandrs output), this means that the MODE_CUR array is increased by one (HDMI-1 HDMI-2), and MODE_CUR[5] becomes aspect ratio instead of being the refresh rate, my solution basically looks for /primary/ instead of /connected/... but no clue if that will mess things up for others.

@etheling said in Update retroarch.sh to enable KMS/DRM on x11 platform?:

Other than patching files under RetroPie-Setup, is there some way to achieve this that I didn't realize?

No, you need to patch the scriptmodule to have both vulkan and KMS support.

@sirhenrythe5th I'm not an expert so I'm not sure. I would assume that would also require a better gpu as well. I mainly use the Pegasus front-end and that got a boost in speed when I switched from a pi3b+ to a pi4.

@mitu Oh ok, that’s a bit of a bummer. At least I know why it doesn’t work though. No big deal, I mainly use it for MAME anyways. Thanks for all your help!

@mitu Thanks a million mitu, it's works. PROBLEM SOLVED. you are genius!

The documentation page needs to be rephrased - while some emulators only have a 32/64 bit version, RetroPie works on both x86 and x86_64.

@mitu Thanks for the help. I will try install opengl drivers and try launch game again. If the probled will be solved , i type about this

@mitu

Yeah, I don't know. Maybe I'm missing dependencies..
Well thanks for helping anyway. It's appreciated.

It seems like the multiplier is locked. I think I was able to track down a reasonably priced 3.1 ghz core 2 to replace it with. Once I upgrade the graphics card in my main PC, I'll probably put the geforce 570 in there, too.

Thanks. I will check tonight. I think , I will just start from the beginning with Ubuntu anyway if that is more stable

okay i have mode you script a bit
im using ubuntu 19-04 x64
make a folder named splashscreens in $HOME/RetroPie and put all your videos in that folder
put this in you script
chmod 755 you script

this script plays a random video form this folder and load emulation station
the only isuse i have whit this is it show a little splash screen on top of video that emulation station is load-et, but it diapers ;)

#!/bin/bash #hides the menubar and desktop #gnome-terminal --full-screen --hide-menubar #starts Retropie gnome-terminal --full-screen --hide-menubar -- emulationstation & #Plays video in VLC then exits. Replace quoted part with your video's location. vlc --random --play-and-stop --play-and-exit --fullscreen --video-on-top --no-video-title-show "$HOME/RetroPie/splashscreens" exit
