Thanks, but it looks the same :(

If you already have libgl1-mesa-dri-dbgsym_20.2.6-0ubuntu0.20.04.1_amd64.ddeb installed then it seems the problem right now is that Xorg doesn't know how to load debug symbols.

https://errors.ubuntu.com/ is also not showing me any Xorg crashes from your system since January. So I think we need to do one of two things:

* Attach a debugger to the Xorg process before it crashes; or

* Configure Xorg to dump core properly and not try to catch its own crashes.
