The best would be to report the issue to the upstream, gitlab.freedesktop.org Issues.

I would like to. But I'm unsure which repo exactly. And also it seems to me that I have several problems which I would like to untangle first to tackle them independant of each other so that we can have good support for this hardware. For example in dmesg (also posted in original bugreport) I see the following, that looks not normal to me, as well:

All I can say that it seems that "something is wrong", but I don't have enough knowledge to understand what. Nor to understand which things are related. I would like to find somebody to understands these messages, can tell me what test and what information to provice. With the goal to have this hw supported well since AFAIK this is one of our new standard company laptops now. So again, I'm not even sure which components are relevant here (kernel, missing drivers, missing support, noveau..). It seems to be several problems. -- You are receiving this mail because: You are the assignee for the bug.

The target to report depends on the result. If it's intel: https://gitlab.freedesktop.org/drm/intel/-/issues If it's nouveau: https://gitlab.freedesktop.org/drm/nouveau/-/issues Also, you can try Nvidia binary driver, if the output is from nouveau. -- You are receiving this mail because: You are the assignee for the bug.

Meanwhile we have a Lenovo P16 laptop available for testing in our team. I suggest to use nvidia proprietary or opengpu driver instead of nouveau driver. All external outputs are connected to nVidia GPU.
