@darkpaladin said in RPi4 dual screen with touchscreen:

The immediate issue I have is with the FKMS driver. The Waveshare touchscreen requires me to disable the FKMS driver and use its own configuration, especially since I want to rotate 90 degrees. But if I disable the FKMS driver, RetroPie runs into the SDL/EGL error and will not load the GUI.

On the PI4, disabling the (f)kms overlay/driver will result in an unsupported configuration, with any GPU drivers disabled. You won't be able to use RetroPie with it.

Is there a different driver I should try loading, or do I need to submit a feature request and wait?

No, there isn't. Not sure why the Waveshare screen needs the standard Pi4 GPU drivers disabled - maybe because of rotation support ? In any case, using both screens will require X11/X.org running, at which point you may be able to rotate the display/screens using xrandr/arandr. It's not a supported configuration for RetroPie, but it may help you using both screens at the same tie.

@mitu Yeah I figured that after. I think I couldn't run any commands, so I plugged it out.

I think I was testing to see if the hub worked on USB 2.0 a little bit before the error occured, so I've kept it in a USB 3.0 port. I've been testing for a while now and there don't seem to be any issues anymore. Hopefully, the problem won't come up again.

I paid good money for this card and need it to work. I don't have a working backup yet. Learning the hard way.

We don't support scammers selling pre-loaded systems. Ask them for support or use the image from retropie.org.uk/download.

To use a Switch controller wired, you have to install both of its drivers first:

After this, you must press ZL and ZR to pair it everytime. Working fine on a RPi3B+.

pre made third party, I'll poke around, thanks for the heads up

@mitu Thanks, that appears to have worked! Now the fun of getting SM64 to run smoothly.

Thanks!

Can you provide some more details here for the SN30 and how you paired it. I think I am getting lost. I currently have it in switch mode, and all buttons except a few are working right now. I will try pairing it another way to see where I get.

I've just come back to this and I have it all working as expected. Does anyone know how to map the directions to the d-pad AND the analogue stick at the same time?

@Rancid84 said in Pi 3 b to Pi 4 b:

I just bought a R4 and have an img from R3 downloaded from arcade punks. Are the previous comments still accurate to use this IMG from R3 over my R4?

Third party images are not supported. Do so at your own risk.

@jordanvs read the replies carefully

I updated both last night both work, however lr-PPSSPP has developed a strange lag issue. The game appears to have frozen for a few seconds but the audio still plays, then the screen catches up. Most games are unplayable.

PPSSPP seem unaffected by this.

@Clyde I'm not sure yet, I only took a moment to map because I'm waiting for an image to come out. Then I'll take the time to map properly.

@UDb23 thank you!

@petrockblog Thanks so much!

@Match5t1ck you may want to have a look at this thread.

@mitu Thanks for the info. Sorry for jumping in. My brain didn't register that this was a RPi4 specific thread. FWIW, Turns out my issue was xpadneo README's instructions for raspbian. Installing the raspberrypi-kernel-headers package on 4.5.1 causes the buster headers to be installed on top of the stretch ones (which are already present on the retropie image).

@mitu said in Raspberry Pi4 Image:

@geekinchief As it was explained in the other topic you opened a few days back and is also explained here, the Pi4 is not supported at the moment by RetroPie.
There's more than just Emulationstation than needs modification and testing for it to make it work, so just bypassing the front-end would not be enough.

OMGzorz the Pi4 has been out for OvEr a WeEk NoW!!! Where's my support?? I wanna play PS3 games!!!

</sarcasm>

Great news, will do ASAP!
