[SOLVED] Segfault when running GPU related applications

I got segfault when I tried to run applications that require GPU, like `kitty`, `mpv`.

kitty
libEGL warning: egl: failed to create dri2 screen
[1]    2490 segmentation fault (core dumped)  kitty

coredump: http://0x0.st/HUYY.bin

mpv video.mp4             
 (+) Video --vid=1 (*) (h264 1280x720 29.970fps)
 (+) Audio --aid=1 (*) (aac 2ch 48000Hz)
libEGL warning: egl: failed to create dri2 screen
[1]    2590 segmentation fault (core dumped)  mpv video.mp4

coredump: http://0x0.st/HUYg.bin

`eglinfo` also crashes with segfaults.
output: http://0x0.st/HUYx.txt
coredump: http://0x0.st/HUY3.bin

I have read some recent threads, which I think they seems related:
- [mesa problem / Pacman & Package Upgrade Issues / Arch Linux Forums](https://bbs.archlinux.org/viewtopic.php?id=291519)
- [X segfaulting today[Solved} / Pacman & Package Upgrade Issues / Arch Linux Forums](https://bbs.archlinux.org/viewtopic.php?pid=2140345)

After trying some suggestion, the problem still exists. I am not sure which part of my system cause this problem. I tried to enclose any things that I think it could be related below.

Re: [SOLVED] Segfault when running GPU related applications

EGL driver name: zink

You end up using https://wiki.archlinux.org/title/OpenGL … kan_(Zink)

Skip 

export WLR_RENDERER=vulkan

See https://wiki.archlinux.org/title/Sway#F … VIDIA_GPUs in doubt.

---
Edit: Also https://wiki.archlinux.org/title/Sway#U … s_renderer - do you have https://archlinux.org/packages/?name=vu … ion-layers ?
----

Also maybe remove "nvidia_drm.fbdev=1" again, it causes

Jan 14 15:35:18 kkoyung-pc kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0

and is reported to be still buggy. You don't need that since nvidia_drm.modeset=1 will disable the simpledrm device.

Jan 14 15:35:18 kkoyung-pc kernel: i915 0000:00:02.0: [drm] Cannot find any crtc or sizes

Jan 14 15:35:18 kkoyung-pc kernel: i915 0000:00:02.0: [drm] Cannot find any crtc or sizes

You've all outputs attached to the nvidia GPU? Can you disable the IGP? (Might save your some battery)

Re: [SOLVED] Segfault when running GPU related applications

Skiping `export WLR_RENDERER=vulkan` doesn't help. kitty and mpv still crash with segfault. However, "journalctl -b" showed different errors.

I didn't have "vulkan-validation-layers", so I tried again after installing it. Same errors appear.

I took a look to the coredump of kitty. It seems that it still uses zink. Here are some part of the "coredump info":

I removed "nvidia_drm.fbdev=1". I also removed "initcall_blacklist=simpledrm_platform_driver_init", which should be implied by "nvidia_drm.modeset=1".

Both outputs are attached to the nvidia GPU. I disabled the iGPU from BIOS. Nice recommendation.

---
Edit:
Side note: When I used nvidia driver 535 before, I had to set "WLR_RENDERER=vulkan" and "XWAYLAND_NO_GLAMOR=1" to get rid of random flickering. After upgrading to 545.29.06, a few random flickering came back. After removing "WLR_RENDERER=vulkan" with nvidia driver 545.29.06, those random flickering are gone.

Re: [SOLVED] Segfault when running GPU related applications

You still run into libEGL_mesa and zink

printenv

to see whether you've the environment to trigger that
Otherwise https://wiki.archlinux.org/title/Vulkan … initialize - but the libEGL_mesa.so.0 there doesn't really help.

Re: [SOLVED] Segfault when running GPU related applications

I cannot find any weird things in "printenv".

In "journalctl -b", my system run into libEGL_mesa and zink while sway is starting. I guess the problem comes from sway, so I tried to switch from the AUR package "sway-git" back to "sway" (1:1.8.1-5) in Arch Linux repository. After switching, the problem is gone.

Not sure the actual reason causing this issue. I may spend some time investigating it later. But my system works fine now. I call it a day.

Thanks, seth.
