Issues with RPi5 + Waveshare HDMI display

With Pi OS (64bits) FullHD monitor also fine. Now I have Volumio on my SD card and it’s already night. I’ll upload Ubuntu tomorrow, plus try Waveshare with Ubuntu.

Can you check on System Info Volumio plugin your Pi5 ?? I had Pi5 and unknown procesor. I bought it as Raspberry Pi5.

Today I received confirmation of the order for another Pi5. Will be in Monday but this time on my invoice is “Raspberry Pi5 model B” .

I ask you about System Info because I sell my first Pi5 in Wendesday but I dont’t have screenshots for comparison with new one.

Maybe Pi5 B ( this new one ) it’s not the same Pi5 I had first.

EDIT :

It’s from delivery confirmation.

But now I know that it’s the same, they not use B in marketing.

Everything is a FullHD monitor with Ubuntu

That’s how a FullHD monitor with Volumio works.
edit: Ubuntu working with Waveshare

Ubuntu is using its own kernel, version 6.5.0

the kernel used on RaspiOS and Volumio is the one by Raspberry Pi foundation, and the latest from the master branch is 6.1.64

So it looks it’s a matter of kernel, when the official Raspberry Pi kernel will be fixed, Volumio will be fixed too… Unfortunately it’s not possible to use the Ubuntu kernel on Volumio

Just as a double check, could you please try with RaspiOS?

I instaled 64bit system from Raspberry Pi site:
https://www.raspberrypi.com/software/operating-systems/
via Raspberry Pi Imager and my Waveshare not working too. But maybe I done something wrong. I’m new in this systems…

Raspberry Pi OS 64bit, Waveshare working (installation via Raspberry Pi imager)

What about the Full HDMI Monitor?

Of course, Rpi OS works with a FullHD monitor. FullHD LCD always works even with Volimio.

OK, I misunderstood your problem, sorry

so the problem is only with the Waveshare display and Volumio, because it works with Ubuntu and RaspiOS

I noticed the RaspiOS kernel is the default one from the first image, unfortunately it’s not available on the firmware repo

does the Waveshare display still work if you update the kernel with rpi-update?

I’m sorry, but I’m just a bit of an advanced user and I’m using google translate, so I don’t really understand the question right now. Should I connect Waveshare to Ubuntu and run a firmware update?

no problem, I’ll try to clarify better

if possible, please connect the Waveshare display to the RPi5 running RaspiOS, according to your report it should be working

afterwards, please run the command “rpi-update”, after the reboot please verify if the display is still working

@eMCZe @Wire could you please try this fix?

add the following line to userconfig.txt (if you do from a Windows PC, please use notepad++ to edit the file)

like this ??

yes, exactly

please remove “display rotate” for this test

I removed display rotate and start Pi5.

Still without display but something is change.

Without added line, LCD start backlight after start Pi5 and backlight was still on.

Now, with added line LCD start backlight but after few seconds goes to power off and LCD green LED “no signal” blinking.
