  • Running: swaymsg for_window "[app_id=mpv] opacity 0.5"

    Works as expected on my end, are you missing just executing for_window?

    Note, you can also add multiple rules in the same execution, e.g.

    for_window {
        [app_id=mpv] opacity 0.85
        [app_id=LibreWolf] opacity 0.85
    }
    

    Also, note that app_id of LibreWolf is capitalized in that manner. You can get that information [app_id, shell etc] by running swaymsg -t get_tree





  • Start with the basics, do you see your Nvidia GPU pop up when using vulkaninfo --summary?

    If it doesn’t pop up, verify that you have the correct vulkan ICD files in: $ ls /usr/share/vulkan/icd.d/

    There you should have nvidia_icd.json, nvidia_layers.json. If that’s missing, you’re missing the nvidia-utils part of the driver.

    If they are there, but it still don’t show in your vulkaninfo sumary, you could try to load the nvidia driver manually; modprobe nvidia, also check the kernel logs journalctl -k or dmesg and search for nvidia to see whether the driver got loaded correctly?
