Description

I installed hyprland-git via AUR and on my old notebook it fails to start.

How to reproduce

It has only a dedicated GPU no intel GPU

Crash reports, logs, images, videos

hyprlandCrashReport635.txt

[vaxerski]

is this legacy_renderer?

[vaxerski]

patch.txt try this

[romanstingler]

Unfortunately, no hyprlandCrashReport12833.txt inxi.txt

[vaxerski]

again, is this legacy renderer?

also try this patch.txt

[ShadowS0ng]

again, is this legacy renderer?

also try this patch.txt

Hello vaxry, I tried both these patches on integrated and nvidia without success. i'm have a intel HD4000 and nvidia GT740m GPUs

[vaxerski]

can someone answer my damn question

[romanstingler]

in my case I didn't build with legacyrenderer, I can try

I just

git clone --recursive https://github.com/hyprwm/Hyprland
cd Hyprland
make all && sudo make install

build.log hyprlandCrashReport8735.txt

[ShadowS0ng]

can someone answer my damn question

ok , i tried the second patch with a manual legacyrenderer build and it worked

[vaxerski]

what if you comment out lines 137 and 138 in opengl.cpp?

[Micovec]

what if you comment out lines 137 and 138 in opengl.cpp?

I got very similar error on newer commit.

I can confirm that the second patch and commenting out those two lines works. I can run Hyprland. I still got some errors in the log about drm but nothing critical.

[vaxerski]

odd, why doesn't your EGL impl not support debug true? anyways, gpu drivers...

[vaxerski]

please check if it works now

[romanstingler]

without the patch and removing these 2 lines

    attrs.push_back(EGL_CONTEXT_OPENGL_DEBUG);
    attrs.push_back(ISDEBUG ? EGL_TRUE : EGL_FALSE);

it fails [ERR] [EGL] Command eglCreateContext errored out with EGL_BAD_MATCH (0x12297): dri2_create_context hyprlandCrashReport3406.txt

When I apply the second patch (patch-3.txt) and remove the 2 lines and build the legacyrenderer then HL starts.

strange, because hyperland-git from before AQ worked on this machine and there shouldn't be the legacyrenderer build as far as I know.

for now, it doesn't matter, Vaxry we still love you :P Appreciate your hard work

[Micovec]

I don't know what happened but commit 7c68236 doesn't work. I tried to rebuild it twice and the result is still the same.

hyprlandCrashReport569.txt

[ShadowS0ng]

please check if it works now

in my case it doesn't work when i comment out the mentioned lines. with the patch, it works but some things like blur doesn't work . also i get this error in logs when i exit hyprland:

IOT instruction (core dump) Hyprlandrom display: Broken pipeadd_accelerator: assertion 'GTK_IS_ACCEL_GROUP (accel_group) could not connect to wayland server

i think it may be related to AGS and not Hyprland

[Micovec]

I don't know what happened but commit 7c68236 doesn't work. I tried to rebuild it twice and the result is still the same.

hyprlandCrashReport569.txt

It seems like I commented different lines. I commented out these lines

[vaxerski]

legacyrenderer is broken thats why blur no work

@Micovec odd... does your driver support gles3.2?

[Micovec]

Not sure how to check that. glxinfo says:

OpenGL ES profile version string: OpenGL ES 3.0 Mesa 24.1.4-arch1.2
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00

If you could please direct me where to check that.

[romanstingler]

to add more info, my card /driver is 3.1, as I said for me, it is not crucial

[vaxerski]

yea both of you have drivers too old for gles3.2, I'm confused as to how it worked before

[Micovec]

I've had some problems with blurs not working. For example in hyprlock or special workspaces, there was no blur. But I didn't think much of it since I'm using arch only because I want to check out Hyprland (on which I'm almost a year on) and I'm not skilled in linux world.

[vaxerski]

both of you have GPUs too old to run hyprland without legacy_renderer, and on legacy IIRC blur is broken. Life is life. Closing as solved

is there any chance you can make this work later? i mean it was working before moving to aquamarine :(

[vaxerski]

no clue.

[ShadowS0ng]

no clue.

ok , I hope you fine a way, ty for great work btw.

[romanstingler]

wlroots has a GLES2 renderer which was used, and on my machine it detected EGL1.4 correctly, sorry but I have no deep knowledge about wlroots internals. And on my side I am using my machines for work, so I have all animations and blur disabled. One could argue that I could use something else, but we love Vaxry. :P

hyprland.log

[vaxerski]

but hyprland always used GLES3.2, so I am confused as to how that worked.

[romanstingler]

Could it be that, for some reason, magically it fallbacks to GLES2 (legacy)? Is there a way to find out what renderer is used?

[ShadowS0ng]

this or maybe there's some translation going on in wlroots?(i'm not familiar with rendering stuff so maybe the translation thing is stupid)

[vaxerski]

no, we use gles3 extensions...

Changing OpenGL.cpp L137

    attrs.push_back(EGL_CONTEXT_MINOR_VERSION);
    attrs.push_back(2);

to 0 works for me (3.0 support), I don't know how "correct" it is to do that, but i guess not specifying it before is how it worked? (Mesa/OpenGL fallbacks??)

I commented out these two lines and normal release build now works without problem.(L136, L137). nice job @vaxerski

[vaxerski]

Generally, I always check what I use for compatibilty against GLES3.2. If anything breaks, you're on your own.

[Dickby]

@vaxerski before the switch to aquamarine, my laptop would run hyprland without problem. It's EGL version 3.0 Setting Minor version to 0 works, but if that's not garanteed for the future, do we really want to restrict hyprland to newer hardware?

[vaxerski]

EGL has no 3.0, pretty sure you mean GLES 3.0

3.2 is already almost 10 years old... I can roll back the needed ver to 3.0 but I am unsure about what might break due to this. I don't check extensions for 3.0 compat, only 3.2

[vaxerski]

there, rolled it back. For 3.2-compliant drivers this shouldn't change anything AFAIK

[Dickby]

Love you, thanks

[Micovec]

Thanks Vaxry, you're the best.
