Recently upgraded to Ubuntu 22.04, and it seems like the power-saving feature does not actually turn off the screen(s) after X minutes, but just blanks them. When I manually run xset dpms force off, they do properly turn off and go to sleep, but this and related solutions (e.g. https://askubuntu.com/a/1004163/29252) do feel rather kludgy.

Any suggestions for how to fix this "properly"?

I detected the issue in my system. Since I'm using a desktop, I managed to solve the problem by replacing the HDMI cable with a DisplayPort cable. Now, my monitor completely turns off. I hope this helps.
