The “solution” that I found for this was in /etc/X11/xrdp/xorg.conf, under Section “Device”, changing the value behind Option “DRMDevice” from “/dev/dri/renderD128” to “”.
But disabling it system wide in the Raspberry Pi’s config.txt file does also work indeed, like others mention.

However, it’s all bad.

The Raspberry Pi still has a GPU, albeit a small one, and I want to take advantage of it.
So I want to actually get the Mesa V3D driver working with Xrdp.
Webbrowsers are not the best way to test it though. The most simple solution to actually check what you are using is glxgears -info (check GL_RENDERER to see what you are using).
The animation of shows the same distortion as the webbrowsers when using the V3D driver, while it works “fine” with the llvmpipe. Any video game would have the same issue.

If anyone knows the solution it would be great. Otherwise giving up on RDP and getting back to Wayland and VNC would probably be the better solution.

Hello
Correction:
LVGL 9.2.0 compiles but the graphics are distorted.
Knowing that I’m only a hobby programmer I carefully read the instructions and
tried it on 2 computers and also with your “Buttons and Slider” file.
Same result.
Version 9.1.0 works fine for me.

BTW , for a hobby programmer your site is great.

Regards

LVGL 9.1.0 still works fine.

I have used several BME680 together with a “big” Raspi. It worked a while, but then each time humidity killed the BME680.

What would be a smart idea for housing the sensor?

Tanks

Glad it was helpful!

Hi Sara, thank you for the reply.
The question is – if the 3.3V output on the CYD can power the relay module and four DS18B20 sensors. Any ideas how can I check this?

I have almost exact same relay modules – aliexpress.com/item/32881636778.html.

My CYD has two USB ports, so I was thinking to use USB-C to power the board and Micro USB to power the relay module (I have ordered additional 5V module).

How can I check if the board (the display) can power and control the relay module without destoying the board. I’ve tried to seach for any spec, but wasn’t able to find anything.

I have been running into a compiling error with the webserver library, it started when I attempted to update ElegantOTA (non pro), I have updated and reinstalled both ESPAsyncWebServer and AsyncTCP with no luck.

Error compiling libraries

I use the VisualMicro extension for Visual Studio as my coding environment.
and I use ESPDash in my project which also requires ESPAsyncwebserver.
