@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?

Actually, I've discovered that Retropie doesnt cause the problem, not being in Pixel causes the problem. If I run Drastic as root from pixel, then it works fine, however this requires use of a keyboard for me which I would rather avoid.
