How to enable DRI3 on rpi4

Hello guys.

I’m using manjaro with xfce desktop enviroment on rpi4.

I install extra/mesa-git on my rpi4. But it seems DRI3 support is missing in vulkan.

I followed arch wiki to create /etc/X11/xorg.conf.d/20-nvidia.conf, and set the content of the file as follows.

Section "Device"
   Identifier  "nvidia Graphics"
   Driver      "nvidia"
   Option      "DRI"    "3"

When I use sudo vulkaninfo, the output says no DRI3 support detected.

Now I’m confused about what’s the real problem. I’m not sure whether mesa-git lack the support of DRI3 or there is something wrong with VNC.

I have tried using tigervnc and realvnc. The latter can confirm that it supports DRI3, but I don’t know whether it needs to be configured to take effect.

Thank you for your help.

The rpi4 does not have an Nvidia GPU, so that config will not work…

Why do you need DRI3 on your raspberry pi?

Oh, I just found out that I made this mistake. I have been successfully install vulkan on raspberry pi os before. And follow the steps to install the nvidia driver. Uh, maybe I remembered it wrong. This must be a useless operation.

I just want to run some examples of the iced library. And I may deploy my program to the Raspberry Pi later.

Things went well when I use raspberry pi os and realvnc. I hope it can also be successfully configured on manjaro.
