HDMI output not working on wayland

So I have been trying to get my hdmi port to show up for a while now but only my second monitor shows up:

   640x350       59.28 

apparently I have hybrid graphics, and my Nvidia card handles Hdmi output:

01:00.0 VGA compatible controller: NVIDIA Corporation GK107GLM [Quadro K1100M] (rev a1)

I have downloaded the drivers required but my Nvidia X server settings only gives me Applications Profiles and Nvidia settings configurations. so basically blank.

these are my logs:

Re: HDMI output not working on wayland

Please use [code][/code] tags. Edit your post in this regard.
Also don't copy and paste out of the pager - that's a wrapped rendition of the first page of the journal or some grep.

xrandr output has extremely limited meaning on wayland since it's basically talking to a compatibility shim that prevents randr calls from crashing.
The HDMI output is likely to the nvidia GPU, so let's look there.

"nvidia-drm.fbdev=1" isn't supported by the 470.256.02 - you're might have a hard time with those on wayland anyway, but for starters: *what* "wayland" are we talking about (gnome, hyprland, plasma, sway, weston, enlightenment, …?) because they're all incompatible on this layer, so this matters *a lot*

So i am on hyprland

Re: HDMI output not working on wayland

I followed what was on the wiki but it didn't work and it also says on the wiki, i need to switch to a dedicated GPU but my laptop doesn't have that option on the bios settings but i can switch off switchable graphics but my Hyprland setup crashes. So should i download optimum manager?

Re: HDMI output not working on wayland

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855
What have you done *exactly*?

it also says on the wiki, i need to switch to a dedicated GPU

Where?
https://deepl.com/

And no, you're not supposed to switch any GPU, let alone using optimus-manager.
You want a hybrid setup to have both GPUs drive all outputs and you want to check the situation w/ hyprctl, not any X11 tools.

Re: HDMI output not working on wayland

I've been attempting to configure a multi-GPU setup on my Dell Precision M4800 with Hyprland, following the instructions here: https://wiki.hypr.land/Configuring/Multi-GPU/.

I'm aware of the specific challenges with NVIDIA and Hyprland, particularly the "Other Issues" mentioned on this page: https://wiki.hypr.land/Nvidia/#multi-mo … d-graphics.

My steps and results are as follows:

    I initially configured the hybrid GPU setup as described, but this did not resolve my monitor issues.

    I then entered the BIOS and tried to disable "Switchable Graphics" to effectively remove one GPU from the system.

    This change caused Hyprland to crash upon launch.

    After re-enabling "Switchable Graphics" in the BIOS, Hyprland returned to its previous working state, but my HDMI output is still not detected when running hyprctl monitors.

After reverting the BIOS setting, I consulted the Hyprland Discord server, where I was informed that my specific GPU model is likely incompatible with Hyprland.

Re: HDMI output not working on wayland

470xx drivers lack the stuff that makes Wayland workable on the Prop drivers. You'll either have to opt for nouveau or live with the situation.
