Beta testing • Re: Updating to trixie

Could you please check in trixie, what happens if you delete virtio_icd.json? I would like to know if virtio driver is taking preference over broadcom for some reason...

I will try to debug next week why this is happening, but installing the developer package shouldn't be needed.

I removed virtio_icd.json, but there was no effect. The behavior is the same.

I've been trying to reproduce this issue but I didn't manage to have reproduces this errors:
No issue with or without libvulkan-dev, same running vulkaninfo with our without desktop environment.

I managed to reproduce the issue of falkon needing the eglfs.json pointing on /dev/dri/card1 on Rpi5, but not needing it on RPi4. And I debugged it to eglfs just opening the first available video device without checking if the device is a KMS device. So it just fails when it opens the render node that doesn't have support for display.
A good example about how a KMS device could be identified is what kmscube is doing in find_drm_device when no device is passed as parameter: https://gitlab.freedesktop.org/mesa/kms ... heads#L204

Do you see any error if you run kmscube from the console in the same system. Maybe that could provide us a clue to what is different in your device.
