[SOLVED] NVidia video ports not detected on Wayland

Hello, I'm new here!

So, I have a Dell G3 15 laptop, which is a NVidia Optimus laptop (yay). These are the specs:

[totoshampoin@Dell-Arch-Toto ~]$ lspci | grep 'VGA'
00:02.0 VGA compatible controller: Intel Corporation CometLake-H GT2 [UHD Graphics] (rev 05)
01:00.0 VGA compatible controller: NVIDIA Corporation TU116M [GeForce GTX 1660 Ti Mobile] (rev a1)

I have 3 video ports: a HDMI, a DP, and a USB-C (treated as a DP)
The HDMI and the DP are handled by the NVidia, while the USB-C is handled by the Intel.

When running on X11, it detects all of them just fine. But on Wayland, it detects only the USB-C.

The thing is that other distros (Ubuntu, Fedora, ...) that have Wayland support do detect these ports (with lags, I am aware).
So I'm wondering how do I configure my system for that?

Nvidia Wayland anything needs modesetting enabled, did you do that? https://wiki.archlinux.org/title/NVIDIA … de_setting

Re: [SOLVED] NVidia video ports not detected on Wayland

I'm not sure where exactly I have to enable modesetting (where the initramfs is)
But I did add ` nvidia_drm.modeset=1` at `GRUB=CMDLINE_LINUX_DEFAULT="..."`, in /etc/default/grub

But apparently, it is still disabled

# /sys/module/nvidia_drm/parameters/modeset
N

I think I am using mkinitcpio though

Re: [SOLVED] NVidia video ports not detected on Wayland

Editing that file does nothing, you'll have to "grub-mkconfig" again.

Re: [SOLVED] NVidia video ports not detected on Wayland

Oh yeah, I forgot to mention that I did enter that command, and I did reboot afterwards.

I even tried replacing the dot by a space instead

GRUB_CMDLINE_LINUX_DEFAULT="... nvidia_drm modeset=1"

Still a N

Re: [SOLVED] NVidia video ports not detected on Wayland

There's supposed to be a dot there…

cat /proc/cmdline

Re: [SOLVED] NVidia video ports not detected on Wayland

Okay, well I put the dot back in, mkconfiged and rebooted it

And

[totoshampoin@Dell-Arch-Toto ~]$ cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-linux-zen root=UUID=640cd5fe-3ce6-45d0-b294-98da9e5f7d8e rw rootfstype=ext4 loglevel=3 quiet

Re: [SOLVED] NVidia video ports not detected on Wayland

You're obviously not applying the setting.
Post your /etc/mkinitcpio.conf, the exact grub-mkconfig command you use(d) and the output of "lsblk -f"

Re: [SOLVED] NVidia video ports not detected on Wayland

And where would that put the new config file?

Re: [SOLVED] NVidia video ports not detected on Wayland

... Oh
I'm supposed to type "sudo grub-mkconfig -o /boot/grub/grub.cfg" ?

____ EDIT ____

Well, I just entered the command, and it works now

Granted the monitors lag quite a bit, probably because the two GPUs are constantly exchanging...
