Rebooted and then hyprland wasn’t starting.
Tried non-wrapped hyprland. Logged in sucessfully.
After debugging, found that export GBM_BACKEND=nvidia-drm was causing problem.
Relogged-in by commenting above line in the wrapper. Logged in sucessfully.

Questions

What is GBM_BACKEND used for? (Tried googling it but, I wasn’t able understand everything.)
Do I need it? If yes, then why?

You can use GBM_BACKEND=nvidia instead, it works on my computer

You can use GBM_BACKEND=nvidia instead, it works on my computer

Don’t do that! If you switch GBM_BACKEND=nvidia-drm with random letters (GBM_BACKEND=asdasda) you will still get the same result! (Booting, but not using Nvidia)

I have the same issue with xorg-xwayland-23.1.0-1, downgrading it to 22.1.8-1 fixed the issue

Doesn’t fix it for me…

Latest nvidia driver update seemed to break running hyprland for a friend of mine.(same error) Downgrading nvidia-dkms and nvidia-utils fixed it.

Torvalds is right about nvidia…

Also behaves weirdly on my system… This solution works, but using nvtop shows that it DOESNT EVEN RECOGNIZE MY GRAPHICS CARD ANYMORE!!!

I’m actually ripping out my hair as it seems like a package caused this issue, as a clean-install worked with the previous settings…

Will report my findings if any package removal solves it…

@LazarusCat59 Can you try with a comma instead of an equal sign? (How it is in the official Hyprland documentation)

I also got it working with an equal (NVIDIA 535 Drivers) so I don’t really know honestly if this solution actually works…

Sorry, I just meant the variable’s value is nvidia-drm, not anything about the syntax I used. I did use the syntax env = GBM_BACKEND,nvidia-drm. The variable is being initialized correctly and doing echo $GBM_BACKEND does give me nvidia-drm as output, so I’m pretty sure it does work. Sorry again for my lack of proper wording!

LazarusCat59 on Nov 5, 2023

I used to have this issue on 535 drivers, but the new driver version 545.29.02 has fixed it for me and Hyprland now starts with GBM_BACKEND=nvidia-drm.

LazarusCat59 on Nov 5, 2023

Well as far as I think what’s happening (don’t trust me on this) This only happens with systems that have multiple GPUs…

Hyprland starts up searching for your dedicated graphics card and finds your integrated one first resulting in its usage instead of the dedicated one…

It chooses that one thinking it’s Nvidia while it’s Intel‘s Graphics and calls the wrong commands causing a crash!

(That’s what I think is happening anyways…)

So hopefully (Nobody has tested this afaik on here) if you have a MUX Switch (on a laptop) or a system with no integrated graphics (AMD+Nvidia not Intel+Nvidia) then it could work…

Eclextic on Oct 3, 2023

I actually have a question on all of you, that could be the reason for this bug… Do we all have Hybrid Graphics? Like a laptop? Can someone test it on their Desktop if possible?

Same issue on the desktop. I have a 1080ti and the IGPU is enabled

MysticBytes786 on Aug 1, 2023

Much work but to no avail…

I have looked through multiple article by now and couldn’t fix it (neither downgrading Hyprland, nor removing any packages worked). Keep in mind I have only tried packages that SHOULD have a any kind of relation with GPU work…

Even still I found some good resources! It seems like the Nvidia patch is based on wlroots (would love to have the git repo grrr) and whenever my Hyprland launch crashed it would report something about this file (line 847): Wlroots’ Gles2 Renderer code

Sometimes (though randomly/happened only once) I also got a crash from this file, while forcing Hyprland to run using sudo (–i-am-really-stupid flag) Wlroots’ Wayland Backend code

These are the logs when launching with downgraded nvidia drivers (remember these make the card not show up anymore) and it seems like there were already issues/errors with the patch before? That were just being ignored? There are numerous errors in this…

The launch logs

It also seems as if the Intel Drivers are taking over?

Also the arch wiki seems to say that you can see which backend is being used for Nvidia (GBM or EGLStreams) using this command journalctl -b 0 --grep "renderer for" but I get no entries?

That’s it for what I found today… I do have an another NVME Drive on which I’ll REINSTALL THE WHOLE THING AGAIN (ffs) and see if we can find the actual buggy package by rebooting after every package install… (I hate myself, yes)

To quicken the process I’ll do archinstall and a Hyprland Installer Script that I found that seems to do exactly everything I needed from Hyprland anyway (with proper Nvidia installation) so if THAT works I’ll copy what that script did and see what exactly is happening.

For now I’ll go and sleep 😴 See you tommorow!

If anybody got any kind of clues, then lets Kamehameha this sh*t together.

Oh and btw the Hyprland Discord (specifically the #hyprland-nvidia channel seems to be the place to report bugs?) AUR package maintainer’s words: Hi all! Just want to clarify some things. a) I am not a technical support person. (UPDATE: There might actually be an issue, but I need to test it on my personal machine.) If you want help with your individual issues, please join the hyprland discord and send in a message to either #hyprland-help or #hyprland-nvidia (not linking it here because I’m unsure of the AUR linking policy).

I’ll try to see if I can do something there with the devs…

I’ve updated to 545 and env = GBM_BACKEND,nvidia-drm now works. But I see no changes with or without it.

Try launching a GPU application without passing in prime-run… Does it automatically utilize the GPU? (Blender, A game, Firefox with WebGPU, etc.)

I don’t use prime-run to lunch apps. They all run on the Intel GPU. The external display is wired to the Nvidia GPU in this laptop.

I repeat don’t install this, downgrade! Prime (prime-run) also stopped working and it seems like running games without prime will just run them on the iGPU… (With 545 Drivers I got 240 fps on a 2D game, with the 535 Drivers using prime-run more than 480 fps…)

Ah I myself am not really having those issues, I do have the GPU show up perfectly fine and I can play games pretty fine (excluding issues I already had on older drivers). So I guess it might just be different experience for different people.

LazarusCat59 on Nov 5, 2023

@LazarusCat59 Can you try with a comma instead of an equal sign? (How it is in the official Hyprland documentation)

I also got it working with an equal (NVIDIA 535 Drivers) so I don’t really know honestly if this solution actually works…

Sorry, I just meant the variable’s value is nvidia-drm, not anything about the syntax I used. I did use the syntax env = GBM_BACKEND,nvidia-drm. The variable is being initialized correctly and doing echo $GBM_BACKEND does give me nvidia-drm as output, so I’m pretty sure it does work. Sorry again for my lack of proper wording!

Ok so testing myself I got it to work, but we have the problem again, that nvtop only shows my integrated graphics card and not my dedicated graphics card…

I want to say, Hyprland feels more responsive though, but I feel like I’m experiencing the Placebo effect…

I’ll test further!

Eclextic on Nov 5, 2023

As far as I can tell it makes no difference whether you have the variable set with env = GBM_BACKEND=nvidia-drm or not at all, so I suspect it’s just invalid syntax. Either way I see the card in nvtop and am able to launch other apps with prime-run (see https://wiki.archlinux.org/title/PRIME#PRIME_render_offload) to use the dedicated card. Hyprland is clearly still using the Intel card.

Yes I am too able to see Nvidia GPU in nvtop. I can also disable Nvidia GPU completely using supergfxctl. And now I’m also able to use prime-run for blender (Thanks for that @lkm, I thought wayland doesn’t support nvidia-prime). before removing GBM_BACKEND=nvidia-drm, blender used to work smooth, now using prime-run it again works smooth

What did work for me in NixOS after you mentioned the hypothesis with the instructions being sent to the intel card. I turned off offloading altogether. Unfortunately I do not know how to set it in non NixOS distros but here its basically this. Going from

# ...
  hardware.nvidia.prime = {
    enable = true;
    enableOffloadCmd = true;
  };

# ...
  hardware.nvidia.prime = {
    sync.enable = true;
  };

Obviously that comes with all the downsides of turning off the ingetrated gpu but at least Hyprland is working with the dedicated GPU.
