Hello!
Trying with the DRM platform this time.
Since only the ES2 variants of GLMark2 work, I'm specifying the GLES renderer.
It works for a few seconds then freezes.
The strace shows that the software can't open anymore files.
I've included an lsof log that confirms this.
I tried increasing the number of FDs with ulimit and that gave it a little more running time but it ultimately froze.
It complains about not finding rules/evdev but I believe that's a symptom not a cause. The file is there.

How do I get this running?
Thanks in advance.

(The simple log is from a later run with the same outcome.)

I am facing the same issue on a raspberry pi 4. Do you have any updates? I have tested with cog 0.16.1 (from debian sources) and with cog 0.18.4 build from source.

This fix won't work for me, but let me suggest you run it inside cage kiosk.
cage -- cog --platform=wl "https://www.github.com"
I also have an RPi4 and cog w/drm failed after a little while. But it's running ok with cage.
Unfortunately, our project calls for a TinkerBoard 2, and this doesn't work.

Yes, it worked with cage and wayland (wl). However, I can't manage to get it to work with DRM even when using cage. I wanted to use DRM to avoid overhead.
