If I had to guess (and I am, lol) I'd say it's probably due to your old kernel version. You're running 5.4 which is pretty long in the tooth. With Fedora I get 5.10.19 out of the box.

There are ways to get a recent kernel in Ubuntu, but it's been a long time since I tried it. And there are some drawbacks but again, it's been such a long time I don't remember the details.

EDIT: And my launch options are only really suitable for an Optimus laptop (i.e., one with hybrid Intel and Nvidia GPUs.)
