[EGL] command: eglInitialize, error: EGL_NOT_INITIALIZED (0x3001), message: "DRI2: failed to load driver"

I was having some trouble with having no more space left on the sd card, so I'd thought to use the opportunity to also update to debian trixie

(I'm running this on a raspberry pi 3B)

However, I ran into some issues with the labwc container which were not present on bookworm:

I've tried googling the error, but was unable to pinpoint the exact cause. The error seems pretty common when running labwc inside docker.

Just went down the list of releases. The last 2 trixie releases produce these errors

Thet last bookworm release is fine.

I tested the new trixie releases on a pi4 with no problems ...

One thing I noticed now:

00:00:00.245 [ERROR] [render/egl.c:319] Software rendering detected, please use the WLR_RENDERER_ALLOW_SOFTWARE environment variable to proceed

So I added this value to the labwc container which reduced the reported error messages. So if you are willing to test trixie on the pi 3B again, let me know if it works now. If you still have the (old) trixie installation you can run docker compose pull in /opt/mm/run to get the new labwc container.
