How to configure eGPU + use the NVIDIA driver?

Now that Fedora 36 comes with Wayland by default and supposedly the NVIDIA driver works with it (really?), how do we configure this?

DO NOT say “egpu-switcher” or “gswitch”. They don’t work and are designed for X11.

On F36, when I tried gswitch and logged in with XOrg, nothing worked.

I tried all-ways-egpu and that sort of worked. However, I could feel that the NVIDIA driver wasn’t working. It was kinda laggy.

What I would like the definitive answer to is this:

Which files to do I need to edit?

What do I need to add comment out?

I don’t care if it’s X11 or Wayland, although I’d prefer Wayland since that is the “future” :roll_eyes:.

Of course, I am using Gnome.

Any help would be appreciated by myself and every other idiot who bought an eGPU hoping to use it with his laptop at home, and then grab his laptop to call when the road or duty calls.


Heinrich (aka: TheBigDuck) :duck:

You first need to install the nvidia driver from rpmfusion then allow the kernel modules to build.
Reboot to load the driver.
It should now be available.

We know nothing about your system, what drivers you have installed, or anything else.

Please post the output of inxi -Fzxx in </> preformatted text tags available on the menu bar above. Also the output of dnf list installed *nvidia*

Here are the steps I took.

  2. Enabled Third Party Repos
  3. dnf update.
  4. Did the update via the Software Store (ugh).

I have been having almost exactly the same issues. I just got an nvidia 160 with a Sonnet 750 enclosure. Running a Thinkpad T480 i5-8250u and have tried EndeavourOS (best so far but I screwed the kernel up), then PopOS (wouldn’t even install half the time), Fedora (almost exactly the situation you are describing), Ubuntu(finally got everything working nearly flawlessly, but there is lag that is unbearable), and now I am on my other ssd (Windows 11) where everything, infuriatingly, works without a hitch.

I mean, fuck Nvidia for not respecting an entire community, but in the meantime. Have you found a solution?

That was the Fedora deal, literally everything worked perfectly, and the little Fedora logo would even pop in and out of the 4K display on login and logout, but the would not have a signal. Even in display manager, it recognized it and I could send windows over there. Literally just no output.

There is no solution YET! But I testing various things and so far nothing.

I do not want to “COWBOY” any files But when I get the solution, it will be posted here for all to see!
