@retropieuser555 The touchscreen is connected in a case with a ribbon cable connected directly to the RPi.

@Fingerprint
Downloading a new image worked! for now.
Everything seems to be working, i'll refer back to this forum if i need anymore help. Thanks.

@hopwon said in Using official RP 5" DTS IPS Screen for hotkeys, box art etc.:

My question do you think the RPi4 handle the additional screen?

Yes, it should work fine.

How to replicate the problem: screen of pcx game is cropped and moved to bottom right. SNES games and the EmulationStation UI are ok.

I found a problem and it is now solved. I ran lr-dosbox-pure in verbose mode and in log /dev/shm/runcommand.log I found error:

eglCreateImageKHR: failed to create image for buffer

After searching for a while on the Internet, I found a tip for editing the file /boot/config.txt and add the line:

gpu_mem = 256

After this the display no longer flashes (flickering) and everything works fine.

I still have to figure out how to emulate a mouse like a touchpad...

@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.

@ehawkins2232 You don't need to comment out the mhs35overlay line, the config file can have multiple dtoverlay parameters - you just need to un-comment the line with dtoverlay=vc4-fkms-v3d.

I agree! Would be pretty nifty to actully have it being USED as a touchscreen! :)

Emulationstation doesn't support mouse controls, only keyboard or gamepad navigation, so I would say no, it's not possible.

@AlexanderN07 said in Retropie auf 3.5 inch kuman touchscreen nutzen:

Hallo, ich habe mir mir ein Raspberry Pi 3b+ geholt und wie gesagt dazu ein kuman 3.5 inch touchscreen ich wollte fragen ob jemand weiß wie man auf dem Touchscreen Retropie benutzen kann?

PS: ,, DANKE FÜHR EURE HILFE! "

As this is an English speaking forum, could you possibly post a translated version so that assistance can be offered please. I wouldn't want to trust Google translate.

@mitu Yeah, it seems to. I'll try to switch over to Pegasus, that may offer touch functionality.

@bubbypop666 Adafruit carries them.

I tried finding my original posting but couldn't so I though it might not have gone through.

@felixlee0530

Good to know. I tried a handful of games a while back and didn't have any luck myself, but it makes sense that some of the less demanding games would be playable. What kind of frame rates were you getting?
