Description

Hyprland (post-aquamarine) is crashing on startup, claiming it can not find a GPU.

How to reproduce

Start Hyprland with greetd or from tty, it crashes almost instantly.

Crash reports, logs, images, videos

hyprlandCrashReport111372.txt

[Ciflire]

I've had the same problem Changing AQ_WLR_DEVICES to WLR_DRM_DEVICES fixed it for some reason

[alyraffauf]

hyprlandCrashReport57187.txt

Same error on another PC, neither are multi-GPU setups.

[alyraffauf]

set env = AQ_DRM_DEVICES,/dev/dri/card1, same crash.

[GimmeDataNow]

I have the same exact issue, I have tested AQ_WLR_DEVICES, WLR_DRM_DEVICES, AQ_DRM_DEVICES, none change the crash message.

(in order:) hyprlandCrashReport133.txt hyprlandCrashReport152.txt hyprlandCrashReport1423.txt

[bjsemrad]

If I try to launch from Gdm login as well, I get the same / similar error as the other crash reports. If this helps at all, I'll grab crash report later.

[ikalco]

can you give hyprland log with HYPRLAND_TRACE=1 and AQ_TRACE=1

[GimmeDataNow]

I am not sure if you mean setting export HYPRLAND_TRACE=1 and export AQ_TRACE=1 in the shell and then running Hyprland or setting this as an env var in the hyprland.conf, but I've done both. Here are the logs:

hyprlandCrashReport1334.txt hyprlandCrashReport1479.txt

[ikalco]

i meant something like this HYPRLAND_TRACE=1 AQ_TRACE=1 Hyprland from tty then give log from /run/user/1000/hypr/$HYPRLAND_INSTANCE_SIGNATURE/hyprland.log btw $HYPRLAND_INSTANCE_SIGNATURE will prob be unset when you crash back to tty so just grab the newest file from there

[GimmeDataNow]

Ok, this is weird. when I do HYPRLAND_TRACE=1 AQ_TRACE=1 Hyprland then Hyprland runs just fine, but Hyprland doesn't wtf. Anyways here is the log of it running:

hyprland.log

Btw I am running nixos, so I can share my whole system if you want

Edit: After another reboot this no longer happens and it just doesn't work anymore.

[ikalco]

try setting AQ_DRM_DEVICES to intel igpu when running from tty aswell and give the same log the hyprland.log you gave is using an nvidia gpu

[GimmeDataNow]

I don't have an intel igpu. Here is what lspci | grep -E 'VGA|3D' returns: 07:00.0 VGA compatible controller: NVIDIA Corporation GP106 [GeForce GTX 1060 6GB] (rev a1)

Anyways, here are some more logs in case you care (Hyprland crashes):

hyprland.log

hyprland.log

EDIT: I have set AQ_WLR_DEVICES, WLR_DRM_DEVICES, AQ_DRM_DEVICES all to /dev/dri/card1 in the hyprland config. And it now works even after several reboots (without the HYPRLAND_TRACE=1 AQ_TRACE=1 ). Could anybody else also set all these to verify?

[ikalco]

this seems like you have simple-framebuffer enabled in your kernel, could be from upgrading to 6.10.0 try putting initcall_blacklist=simpledrm_platform_driver_init in your kernel params

[ikalco]

you only need AQ_DRM_DEVICES env var to be set also setting explicit gpu will make AQ not use simple-framebuffer which fixes your issue

[GimmeDataNow]

this seems like you have simple-framebuffer enabled in your kernel, could be from upgrading to 6.10.0 try putting initcall_blacklist=simpledrm_platform_driver_init in your kernel params

Does initcall_blacklist=simpledrm_platform_driver_init affect any other applications?

Regardless this issue seems to be fixed on my end somehow. I'll keep testing and if there is an issue I'll be back

it might, but you're right you should just use AQ_DRM_DEVICES instead

[bjsemrad]

I have a different error with AQ saying it cannot find the GPU..... hyprlandCrashReport7871.txt

[ikalco]

[LOG] [AQ] drm: Explicit device list /dev/dri/card1 [ERR] [AQ] drm: Explicit device /dev/dri/card1 not found

are you sure /dev/dri/card1 is there if it is give the same trace hyprland.log as the other guy did

[bjsemrad]

I am sure.....

Anyway attached the latest crash log, which now atleast shows a different error, I just removed AQ explicit env and tried again now it looks like just wayland.

Attached for reference. hyprlandCrashReport7109.txt

Or did I miss understand the log you wanted?

[ikalco]

sorry i meant the /run/user/1000/hypr/$HYPRLAND_INSTANCE_SIGNATURE/hyprlandd.log and the new crash seems related to the other issue so i might know what it is

[bjsemrad]

Whoops sorry I missed that here you go:

hyprland.log

[fiskhest]

Setting env = AQ_DRM_DEVICES,/dev/dri/card1 fixed it for me, on a multi-GPU intel / Nvidia setup (albeit with the Nvidia GPU disabled)

[ikalco]

@bjsemrad try aquamarine with this patch patch.txt

[sjcobb2022]

I am having the same issue. Also on NixOS with a hybrid /Nvidia laptop.

With wlroots I had a symlink to /.config/hypr/card. This no longer works, and says that the card does not exist. This may be a totally separate issue, as this means aquamarine may not be able to resolve symlinks.

Hardcoding the path (to my amd iGPU) gives me this crash log:

It seems to find the card, start aquamarine and the Wayland backend, but the backend is unable to start.

Every single post on this thread is using NixOS, so I assume it is a nix path issue, which would make total sense given the logs.

I hope this info helps.

[vaxerski]

the wayland fail is expected as you are running from a tty and not on a wayland compositor. That's a non-issue.

The issue is:

[ERR] [AQ] Couldn't open a GBM device at fd 25
[ERR] [AQ] Cannot create a GBM Allocator: gbm failed to create a device.

[sjcobb2022]

Ah so a different issue @vaxerski?

[vaxerski]

I dont remember all the reports but most were about this I believe

[sjcobb2022]

I am sure.....

Ah I didn't see this post getting the same error. With a different file descriptor but nevertheless, the same GBM error.

After quick search (I'm on my phone because I haven't gotten round to pinning hypr to an older version yet), it seems that similar issues on different platforms are caused by outdated or broken Mesa drivers.

Not sure if this helps. Thank you for all your hard work and support @vaxerski

[bjsemrad]

the wayland fail is expected as you are running from a tty and not on a wayland compositor. That's a non-issue.

The issue is:

[ERR] [AQ] Couldn't open a GBM device at fd 25

[ERR] [AQ] Cannot create a GBM Allocator: gbm failed to create a device.

Ok that clarifies it, if I try from Gnome login (GDM) I get the same behavior, I'll have to check if it's running Wayland. This worked fine under WLroots so just trying to understand what is different now.

vaxry im pretty sure the issue is that gbm_create_device wants the fd from the /dev/dri/card1 but reopenDRMNode gives it a drm lease thats what the patch above removes btw

[vaxerski]

well then I'll let the people speak if it works. On my system it does the lease and we ok.

[bjsemrad]

What are you using to launch? I will try the patch above but also can swap to SDDM or another login manager.

[vaxerski]

I have no issues with hl from main on my desktop or laptop (desktop tty, laptop sddm)

[bjsemrad]

For what it's worth my above crash and hyprland log above was from running Hyprland from a tty but it did not launch for me on Linux 6.10.0 and latest hl.

For those on NixOS who want to test, I have created a patched fork for easy maintenance.

You can put this in your inputs:

aquamarine-patched = {
    url = "github:sjcobb2022/aquamarine-patched";
};

hyprland = {
  type = "git";
  url = "https://github.com/hyprwm/hyprland";

  submodules = true;
  inputs.nixpkgs.follows = "nixpkgs-unstable";
  inputs.aquamarine.follows = "aquamarine-patched";
};

After testing with this patched version for a while, with a variety of environment variables, I am getting the same error with a little bit of additional context:

hyprlandCrashReport4361.txt

It is able to open the node, but the GBM device still fails to initiate.

[LOG] [AQ] reopenDRMNode: opening node /dev/dri/renderD129

oops, try this patch.txt

[sjcobb2022]

Hey @ikal

So it is now reopening the DRM node of the specified card, but it is still crashing with the same issue.

hyprlandCrashReport4016.txt

[LOG] [AQ] reopenDRMNode: opening node /dev/dri/card1
[ERR] [AQ] Couldn't open a GBM device at fd 27
[ERR] [AQ] Cannot create a GBM Allocator: gbm failed to create a device.

I also made a branch where I spammed traces at every step (without any patches applied, and with the first patch applied). You can find that here.

Here is my total log file of that:

hyprlandCrashReport92514.txt

And the necessary fragment:

[LOG] [AQ] Starting the Wayland backend!
[ERR] [AQ] Wayland backend cannot start: wl_display_connect failed (is a wayland compositor running?)
[ERR] [AQ] Requested backend (wayland) could not start, enabling fallbacks
[ERR] [AQ] Implementation wayland failed, erasing.
[TRACE] [AQ] Opening DRM node: 26
[TRACE] [AQ] lesseeID: 1, leaseFD: 27
[TRACE] [AQ] leaseFD Passed: 27
[TRACE] [AQ] Render device has name inside drmIsMaster: /dev/dri/renderD129
[TRACE] [AQ] Assigning primary allocator with fd: 27
[TRACE] [AQ] Creating a GBM allocator with drm fd 27
[LOG] [AQ] Creating a GBM allocator with fd 27
[ERR] [AQ] Couldn't open a GBM device at fd 27
[ERR] [AQ] Cannot create a GBM Allocator: gbm failed to create a device.

So just to clarify, /dev/dri/renderD129 is the same drmMaster with and without the first patch (this is expected as the second patch gets the right card). Given that this is ripped from WLRoots, I guess this is expected behaviour and may not need to be patched?

We then try to assign a primary allocator here.

In the allocator we then try to create a gbm allocator through the C API, here.

This is the core part that fails.

Given that all the patches fail, (including the patch where the correct card is reopened. I am inclined to believe that this might be a super niche nixOS issue, missing a dependency or the such.

Otherwise, we may be handling these file descriptors wrong somehow, and I wouldn't know where. The AQ implementation is almost a mirror of wlroots, so I have no idea what is wrong.

I am totally new to this codebase so please correct me if I am wrong!

[sjcobb2022]

I take that back. Adding all the missing dependencies (including X dependencies) from WLRoots to Aquamarine does not do anything at all.

Very weird issue.

[sjcobb2022]

Just as an updated.

I have been playing around with wlroots vs aquamarine, and it turns out that from wlr I get these errors:

[wlr] [render/allocator/gbm.c:249] gbm_create_device failed.
[wlr] [render/allocator/gbm.c:249] gbm_create_device failed.

This is extremely interesting, as looking through the code at wlroots-hyprland here, this is the only place where this error occurs.

The rest of the codebase (from what I can find), would only ever call any of this function once.

Given that this is the same error we are getting from AQ, I am wondering if there is any similarity between these issues.

I can't find the major different between the wlroots implementation and the AQ implementation, so if anyone knows more about these codebases, help would be great.

[sjcobb2022]

I just want to ask: how many here are using laptops Vs desktops. I'm wondering if that would be a cause for this?

[bjsemrad]

I have a framework 13 running a 12th gen intel (igpu) and a desktop running a 5800X + 6800XT and both experience the same issue. They are both on NixOS.

[alyraffauf]

It's happening on both my desktop and several laptops, all running NixOS 24.05.

[sjcobb2022]

Ok so we are all on 24.05. I'll try 23.11 tomorrow and see if that works.

[sjcobb2022]

Yeh it just doesn't build because of dependencies on 23.11 and I don't wanna patch all of that.

[kbredemeier]

I think i got the same problem. Did anyone figure out to which version I have to pin what to work around this for now? I didn't commit my flake.lock file for quite some time :sweat_smile:

This is my flake I just pin to last release before aquamarine while I debug.

Doing a nix rebuild and update will rewrite the lock file.

f642fb97df5c69267a03452533de383ff8023570 for me

[sjcobb2022]

I know this may not be related, but I feel that https://forums.developer.nvidia.com/t/prime-sync-with-amdgpu-has-black-screen-for-internal-display/198967/12 this forum post could be relevant perhaps?

And in extension this: https://github.com/NixOS/nixpkgs/issues/93489

[sjcobb2022]

I have a potential theory based on those previous posts. The version of mesa that is used in aquamarine and the version used in my drivers is different.

The mesa version here is the stable mesa version 24.0.7

Whereas aquamarine uses the unstable version: 24.1.2

Perhaps this could cause this issue?

To mitigate this, I will build entire system with nixos unstable. If I still get the issue, we know that it is not because of the mess version.

[sjcobb2022]

Unfortunately, this was not the issue. Any ideas?
