Nvidia GPU cannot be used in Wayland sessions

General system Kernel, boot, graphics & hardware

I have a hybrid GPU laptop with 11th Gen Intel and Nvidia MX350. Everything works perfect on X11. but when i try Wayland, the Nvidia GPU aren’t being used, even though i set it as primary GPU with envycontrol it keeps using the Intel one. It’s there, detected but not used.

I’ve done that, same result

Are you on grub or systemd boot? (grub here).

Per @dalto :

You don’t edit the entries. You edit /etc/kernel/cmdline

Then run sudo reinstall-kernels to apply the change.

The entries are dynamically generated so they change.

This is also described in the wiki article.

I have a relatively old install, with grub, but I did swap to dracut.

systemd

i’ll try it brb

/etc/kernel/cmdline output are

nvme_load=YES nowatchdog rw rootflags=subvol=/@ root=UUID=9ef5da68-1342-4895-988c-f80892eeb7f0 nvidia-drm.modeset=1

and i’ve done sudo reinstall-kernels and it still the same

Out of ideas. :frowning:

Just a thought - what packages for wayland have you installed? I have:

kwayland-integration 5.27.3-1 (plasma)
plasma-wayland-protocols 1.10.0-1
plasma-wayland-session 5.27.3-1

And what does inxi -G return, mine is:

Packages?

pacman -Qs plasma | grep -i wayland
11 
local/kwayland-integration 5.27.3-1 (plasma)
    Provides integration plugins for various KDE frameworks for the wayland windowing system
    Qt component to allow applications to make use of the Wayland wl-layer-shell protocol
local/plasma-wayland-protocols 1.10.0-1
    Plasma Specific Protocols for Wayland
local/plasma-wayland-session 5.27.3-1
    Plasma Wayland session

To enable support for Wayland in Plasma, also install the plasma-wayland-session package. If you are an NVIDIA user, also install egl-wayland if it is not already installed, and if the session does not start with the proprietary nvidia driver, also enable the DRM kernel mode setting.

:eye: https://wiki.archlinux.org/title/Plasma#Plasma

Try installing egl-wayland and see if that will resolve the issue.

13

Yes i have egl-wayland installed before

14

It doesn’t show in the output you posted on the installed wayland packages on your system.

15

The command I shared will only show plasma. egl is not plasma-specific.

What application do you use to switch between GPU modes?

17

I use the BIOS, Lenovo Legion 5 AMD/nVidia.

18

i wonder if envycontrol only works in X11 and not in wayland

19

Exactly. Don’t make your life tougher than it needs to be.

I need the Wayland fractional scaling feature, but not desperately
Guess i’ll just wait
