[SOLVED]nvidia prime breaks gnome on xorg

I'm using Asus optimus laptop with rayzen 7 4000 and NVIDIA GeForce MX350

I was fallowing wiki to set up NVIDIA prime run

https://wiki.archlinux.org/title/PRIME# … er_offload

so I downloaded :

https://aur.archlinux.org/packages/prime/

But after downloading and reboot, gnome didn't show up after GDM, DM is ok and while I switch to Wayland everything works just fine, but I don't have prime support on Wayland.
So I made these configurations: /etc/X11/xorg.conf.d/nvidia.conf

Section "ServerLayout"
      Identifier "layout"
      Option "AllowNVIDIAGPUScreens"
EndSection

as it says here:
https://download.nvidia.com/XFree86/Lin … fload.html

but nothing changed.

It's quite possible you don't have to do anything special to set this up; I recently installed a hybrid amdgpu+495xx laptop with GNOME (without any additional Xorg/GDM configuration) and PRIME "just works" (i.e. GNOME will automatically offload when needed).

But after downloading and reboot, gnome didn't show up after GDM, DM is ok and while I switch to Wayland everything works just fine, but I don't have prime support on Wayland.

Wayland and Nvidia don't play well together in a number of situations. For example, while my laptop will allow Wayland when using only the internal panel, as soon as I enable an external display Wayland/GDM will crash and reinitialise to use Xorg, at which point the external display works perfectly (with render offload/PRIME sync/etc. without any need for configuration).

Re: [SOLVED]nvidia prime breaks gnome on xorg

The wiki doesn't mention that aur package, but nvidia-prime from extra repos .

I suggest you switch to that.

Re: [SOLVED]nvidia prime breaks gnome on xorg

(i.e. GNOME will automatically offload when needed).

Does it mean that GNOME is dynamically using the GPU if needed without using prime-run or switcheroo for applications or it is exclusively for gnome-shell?
