Public bug reported:

I thought this was similar to bug #1971149, but that's not the case at
all. Apparently my problem comes from the screen being black but not
suspended (while playing some audio). Suspending the laptop (by closing
the lid or pressing the POWER buttom) and then waking it up solves the
problem.

Let me attach you the log.

I'm on a Mi Notebook Pro 2018 running Ubuntu 22.04, an Intel® Core™
i7-8550U with an NVIDIA GeForce MX150 using Wayland.
