It's not any better on the Nvidia side for Linux sadly. On Displayport if I turn off my monitor I can't get it back, a very common issue. I tried every workaround on earth. On HDMI if I do the same I'm okay but I have to reset the audio stack to get sound back at least 50% of the time. Tons of distros, wayland and xorg, different DEs, all have issues on nvidia, at least with my monitor.
I'm so close to buying a cheap Intel Arc as a display adaptor so I don't lose all my hair.
