At some point, I did something with Terminal and it started working, but cannot reproduce it. The only thing that seems to be really working is to Suspend laptop and come back in Ubuntu (or restart, but that means to close everything + it takes more time). While I wrote this text, it seems to have recovered by itself, it is working right now, but this is unreliable and cannot be used in production (what about stopping it during a presentation, cannot suspend in a meeting). Hopefully, it is some kernel problem, as I reported kernel package.
