Description

Hello Hyprland team,

I'm encountering an issue where Hyprland fails to start on my NixOS system. I've tried various configurations but haven't been able to resolve the problem. I would greatly appreciate any guidance or assistance you could provide. Here are the details:

Issue Description: When attempting to start Hyprland, it immediately crashes.

Error Message:

[CRITICAL] m_sWLRBackend was NULL! This usually means wlroots could not find a GPU or encountered some issues.
[CRITICAL] Critical error thrown: wlr_backend_autocreate() failed!

I've reviewed the documentation and tried the suggested solutions, but I'm still encountering this issue. If there's any additional information I can provide to help diagnose the problem, please let me know.

Thank you for your time and assistance. I appreciate the work you're doing on Hyprland and look forward to being able to use it.

How to reproduce

Steps to Reproduce:

  1. Boot into NixOS
  2. Attempt to start Hyprland session

vaxerski commented 2 months ago

does sway work? or any other wayland session?

This looks like an nvidia issue anyways. @fufexan for nix though

ByteAssembler commented 2 months ago

Cinnamon (experimental) runs under Wayland on the system. Sway, on the other hand, has similar problems to Hyprland.

sifmelcara commented 2 months ago

Have you tried hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.beta;?

ByteAssembler commented 2 months ago

Yes, I've tried that too. I tried different nix channels and also different Linux kernels, but Hyprland would never start.

sifmelcara commented 2 months ago

Try this config and if it still does not work for you maybe try create a NixOS live CD and boot from it? The iso built from this config does work on my 1080 Ti machine (many options here are probably not required)

Save this as flake.nix and run nix build .#nixosConfigurations.hyprlandIso.config.system.build.isoImage

Thank you so much for your detailed suggestion and the NixOS configuration, @sifmelcara. I really appreciate your effort to help me troubleshoot this issue. I've followed your recommendations, and here's what I've found:

1. Existing NixOS Configuration: I integrated your provided configuration into my current NixOS setup. After restarting, I was able to see the SDDM login screen. However, when I attempted to log in, nothing happened. (The hyprland logs show the same error as before.)

2. ISO Build: Following your recommendation, I proceeded to build the ISO using the provided flake.nix. The build process completed without any errors. For reference, the SHA-256 hash of the resulting ISO is (https://github.com/NixOS/nixpkgs/tree/8f48c9241de143e8e60a826d405fa8dec5e49343):

 7fe21509a7ed28e3e1909e6d555df332f6f2345ddb41df3104e93a15b04f29c3

It would be helpful to know if this hash matches what you'd expect, as it could confirm whether the ISO was built correctly.

3. Booting from ISO: Unfortunately, when I tried to boot from this ISO, I encountered a black screen. On one of my monitors, I could see the backlight, while the others remained “off” (actually as before). I suspect this might be because the login screen is typically skipped during live boot, and Hyprland may have failed to start again, similar to my previous attempts.

Since this was a live system, I don't have logs from this boot process. However, I believe the underlying issue might be the same as what I've been experiencing before.

I must admit, I'm feeling a bit disheartened at this point. I'm wondering if there might be some underlying issue with my NixOS configuration or perhaps some hardware-specific problem that we haven't identified yet.

I'm particularly intrigued that this configuration works on your system with a NVIDIA GTX 1080 Ti. This makes me think that there must be some critical difference between our setups. While I don't believe it's related to my CPU (I'm using an AMD Ryzen), at this point, I'm open to considering all possibilities.

Do you have any thoughts on what might be causing this persistent issue? Are there any additional logs or system information I could provide that might help pinpoint the problem?

Despite the setbacks, I would like to continue trying to get Hyprland to work on my system. If you have any suggestions or need additional information, please let me know.

Thank you for your assistance.

It should show sddm login screen first. User will need to type password ("nixos") to log into Hyprland session.

On one of my monitors, I could see the backlight, while the others remained “off” (actually as before)

I have 3 monitors plugging into nvidia card and they all shows sddm login screen and Hyprland properly

While I don't believe it's related to my CPU (I'm using an AMD Ryzen)

FWIW I have Intel CPU

Do you have any thoughts on what might be causing this persistent issue? Are there any additional logs or system information I could provide that might help pinpoint the problem?

It sounds like you have multiple monitors, maybe try using single HDMI monitor first?

Have you ever update NVIDIA firmware? My card have https://www.nvidia.com/en-us/drivers/nv-uefi-update-x64/ applied, and I feel this could be relevant to your "black screen" issue.

GameDungeon commented 2 months ago

This sounds like this nvidia issue I am seeing reports a lot of reports of. I would say downgrade the NVIDIA drivers. https://forums.developer.nvidia.com/t/555-release-feedback-discussion/293652/173

Starnick4444 commented 1 month ago

I've had a very similar crash message, and managed to solve it by setting WLR_DRM_DEVICES. Followed this comment https://github.com/hyprwm/Hyprland/issues/2622#issuecomment-1616067379, In my case /dev/dri/card0 was pointing to simple-framebuffer, and card1 was the correct one.

Is this still a thing?
