External monitor not working with Wayland (missing nvidia drm activation with systemd-boot?)

[shishimaru]

Hi there everyone.

I was using Wayland successfully on Tumbleweed with Plasma Wayland session. I don’t know why, but starting today the external monitor is working on X11 only and not on Wayland.

While on Wayland, I can solve with:
~> su
Password:
localhost:/home/salvi # modprobe -r nvidia_drm ; modprobe nvidia_drm modeset=1

Since I must use systemd-boot in order to boot my system (GRUB won’t work), I’ve edited the /etc/kernel/cmdline as follows:

splash=silent quiet security=apparmor nvidia_drm nvidia_drm.modeset=1 mitigations=auto

(Basically, I’ve only added the nvidia lines, and I’ve already tried to remove the first nvidia option and change the second one in nvidia-drm.modeset=1)

Also YaST Boot Loader confirms that these lines are edited correctly.

I’ve also run sudo dracut -f just to be sure. Unfortunately, nothing is working.

Any ideas?

This is a long shot, but maybe setting the framebuffer in /etc/kernel/cmdline may help by adding:

nvidia-drm.fbdev=1

to the line.

then dracut -f
