Wayland setting primary gpu(NVIDIA)

[segfault (Anil Gurses)]

Hi there,

I recently installed Fedora 36 on my XPS 9520. It has RTX 3050 and I installed all the required drivers from rpm fusion repository(akmod-nvidia:510). However, Wayland chooses Intel gpu as primary gpu. I know that Fedora 36 came with Wayland+Nvidia by default but I can’t say same thing for my setup. How can I set primary gpu to Nvidia for wayland?

PS. It works fine with x11

$ glxinfo | egrep "OpenGL vendor|OpenGL renderer"
OpenGL vendor string: Intel
OpenGL renderer string: Mesa Intel(R) Graphics (ADL GT2)

Thanks

Instructions here but might not work as expected with wayland

[segfault (Anil Gurses)]

It’s not for wayland. I already followed that instructions for x11 but it doesn’t work for wayland. I am specifically looking for some configuration file in wayland as in x11.

This is wayland way I hope you can do it.

[segfault (Anil Gurses)]

Thanks for the reply! I switched back to X11. I just wanted to give it a try to wayland but it was early

NVIDIA proprietary drivers only recently support Wayland framework, Fedora default configuration is Wayland … this explains that, Intel as default GPU, not recent NVIDIA hardware so X11 …

I’m on Fedora Gnome + Wayland + Nvidia/Intel hybrid graphics, any updates on this?

[computersavvy (Jeff V)]

What updates are you looking for?

The posts above show how to use nvidia as primary with wayland and this shows how to do it with xorg.

Nvidia drivers support wayland since the 495 version was released with fedora 35.

[scottytrees]

How do you do it in Fedora 37 exactly? The gnome extension that did it only supported Gnome 42, not 43. I am just a little confused is all.

[computersavvy (Jeff V)]

We need a starting point to answer that.
Does the nvidia driver work for you with wayland?
Is the only issue the desire to set nvidia as the primary GPU?
Is there something else that is of concern?
What version of the nvidia drivers are installed? (that can be answered by posting the output of dnf list installed '*nvidia*' using the Preformatted text tags </> above.)

Here is a similar topic

Setting Option "PrimaryGPU" "yes" in the nvidia.conf does nothing with Wayland

Hi. I have been trying to set my NVIDIA GPU as the primary GPU, but even with the directions here, it still defaults to my Intel Mesa GPU.

[scottytrees]

I’m currently on Fedora 37, Gnome using Wayland with my Nvidia MX150+Intel with proprietary drivers 525 from RPMFusion. I’ll try to post as much information as I can. On Xorg I’ve always run the GPU as my primary and on Xorg the option to do that in Fedora is straight forward enough I was able to figure it out according to the Fedora Docs here. As far as I can tell, I’m using my Intel graphics for like +90% of my Wayland usage, all apps except for maybe Minecraft launcher, open with my Intel integrated graphics. I was just hoping/seeing if there was a simple way to at the very least test how using only the Nvidia GPU on Wayland would fare in comparison. It’s mostly for testing purposes. The link you posted, I also did that for my xorg.conf file btw, but I am now aware that doesn’t apply to Wayland.

X11.conf file doesn’t apply to Wayland. Currently, there is no option for setting Nvidia as the primary GPU. Wayland runs in hybrid mode. By saying that, you can launch apps with discrete GPU but not the gnome shell itself. I don’t know if recent updates brought an option for disabling hybrid mode.

[computersavvy (Jeff V)]

I distinctly recall seeing a couple options posted about making nvidia primary when using wayland, but cannot seem to find them right now. A bit of searching should reveal them though.

[marko23 (Markos Malliarakis)]

You can switch to and back from Wayland and X11 either using GDM login manager or installing/removing ‘gnome-session-wayland-session’ or ‘gnome-session-xsession’ packages. Many apps are compiled with Wayland libraries. NetBSD uses exclusively X11R7 with some Wayland dependencies so at some point you might need to recompile an app …

Well, when you find them feel free to let me know and I’ll test them out on Fedora 37
