Linux

Not sure if this is a good place to ask for help, but I have scoured the internet and no one has a solution, so hopefully this question helps me as well as others.

I'm trying to get my computer to run at its best when on Hyprland. I have an MSI Raider GE76 which has an Nvidia GTX 3080 Mobile and an Intel Tiger Lake CPU with integrated graphics.

I typically have an external display over display port, an Ultrawide 3440x1440@60Hz, and the internal laptop display is on eDP at 1920x1080@360Hz. Note tho that while I often have the dual screen setup, I do need to be able to go to just the Intel display. The Nvidia GPU drives all outputs (DP, HDMI, Thunderbolt) EXCEPT for the eDP which is connected to the Intel card.

On X11, I could use reverse prime sync to use the Nvidia card for everything and just have the Intel card draw whatever the Nvidia card renders. This worked well. Unfortunately there isn't anything like that for Wayland, and I don't have a hardware switch to put the eDP on the nvidia side of things.

This means that I have to use the default prime modes to run stuff on the nvidia card which makes the second screen incredibly laggy. Now, I can disable the i915 module and the external display becomes buttery smooth, but I can't use my built-in display (which means I also can't use the display when I'm not connected to the external monitor).

How can I get both to work well on Wayland?

Can I run the external display exclusively on Nvidia and the internal on Intel with Prime? That could work, but idk if that's possible.

What's the optimal way to set up an external display on Wayland with and Nvidia hybrid-graphics laptop? Bc right now I'm thinking of just going back to X11 and praying it gets enough support to live until I can get a decent Wayland config.

I have wondered many times.

Of course I can always use a browser but it's overkill.

The same goes for yad or zenity, they pull in webkit which is a full-fledged browser engine, and at least yad does not have an offline mode.

I just want to look at some local HTML (incl. images) & CSS styling.

I am having issues with my linux machine running openSUSE MicroOS. It runs fine but I can't power it off via SSH. I tried shutdown, poweroff and halt but no command turned the machine off. I then have to physically push the power button but I don't feel comfortable doing that too often because I might interrupt some processes which are still running? Is there something I could still try or something I did wrong?
