This is the expected behavior on nvidia prime. Not a bug.

qoijjj commented 3 months ago

@petete1 So you're saying that KDE/Kinoite has a bug then? This only occurs on Bazzite, not Kinoite.

petete1 commented 3 months ago

AFAIK Kinoite doesn't include the proprietary nvidia drivers.

qoijjj commented 3 months ago

@petete1 I'm talking about ublue's kinoite-nvidia image. It doesn't have this issue.

petete1 commented 3 months ago

I just did a quick test on kinoite-nvidia, and it's true that Xorg isn't running. Now tried bazzite-nvidia:testing and it's the same. Looks like the new 555 driver changed things and there's no Xorg process on the dGPU anymore. So, nothing to fix, you only have to wait for the new driver to get into bazzite.

For the record, that Xorg process has been there since nvidia implemented prime gpu-offloading, that's why I took it for normal.

@petete1 that's good to hear!

it happens on gnome and other DEs too, but I don't think it's supposed to on a wayland session unless an application specifically needs an xorg session and it needs that session running on the dgpu.
