Regression?

I don't know, I started using Hyprland only recently

Description

Switched from arch to hyprland.
Tested on several machines and a VM, all with diverse hardware.
cannot for the life of me get it to work without nixGL.
runs like a breeze in nixGL.

How to reproduce

Unsure of reproduction.
The only two variables I possibly see being relevant are that my system is UEFI, and the disk is impermanent.

oop, forgot to include stack trace, one moment

try -git

[Notarin]

try -git

Is this a cli flag?

[nnyyxxxx]

no, compile from source and see if it still crashes

[nnyyxxxx]

from the trace and logs, looks like hyprland couldnt:

start the wayland backend - failed because another compositor is running
trys to fall back to gbm/drm - failed because it cannot access your gpu

stops trying and throws an error

probably not an issue with hyprland

[nnyyxxxx]

install opengl / mesa libs, this will probably fix your issue, and explains why nixgl works

[C0Florent]

Perhaps your NixOS is not up to date properly.
I noticed a similar bug recently when trying to upgrade from Hyprland 0.45.2 packaged by nixpkgs 24.11 to Hyprland 0.47.2 provided by the flake in this repo. Some recent changes required some system-level changes in NixOS, so for me upgrading my NixOS from 24.11 to the unstable from a few weeks ago made it work. I don't how "old" is your unstable, so my advice may or may not be relevant to your problem

[Notarin]

@C0Florent I have tested off of the flake, which is the latest commit, and the github flake, which is even more recent. I have tested several versions, none of which worked.
programs.hyprland.enable is supposed to fix the driver issues, but for whatever reason is ain't. So I plan to see if I can figure out how to get them into the environment.

Sorry, but just to be sure we're on the same page: my message was about the version your system is built with − not necessarily your environment packages version − which according to your "System info" is nixpkgs unstable from Nov 22, quite a while ago. I did not make that really clear in my first message and your answer doesn't disambiguate, so I'm making myself clear, sorry to repeat if you already understood.
You may update your system info in the issue description to make things clear

To elaborate further, if you indeed have the correct NixOS version, can you see the drivers in /run/opengl-driver/? IIRC when I was getting a crash it was a dri_gbm.so which was not found during Hyprland startup, which is supposed to be located at /run/opengl-driver/lib/gbm/dri_gbm.so.

If that's not it then I'm out of ideas

[ERR] [AQ] Couldn't open a GBM device at fd 29
[ERR] [AQ] Cannot create a GBM Allocator: gbm failed to create a device.
[CRITICAL] m_pAqBackend couldn't start! This usually means aquamarine could not find a GPU or encountered some issues. Make sure you're running either on a tty or on a Wayland session, NOT an X11 one.
[CRITICAL] Critical error thrown: CBackend::create() failed!

quite self-explanatory. Your driver did not let us take your gpu. Likely a misconfiguration of some sort.
