Description cerberus1746 2023-10-22 04:22:07 UTC

Obs: This was resolved by installing x11-drivers/nvidia-drivers-545.23.06 (beta version)

I am using a Alienware 15 r2 (https://laptopmedia.com/laptop-specs/alienware-15-r2-41/) it has optimus, intel integrated graphics (Intel Core i5-6300HQ), no I can't disable it in the bios, and a nvidia card (NVIDIA GeForce GTX 965M).

In sum with Plasma Wayland and Hyprland vkcube-wayland literally crashes with a segmentation fault. And I have no idea why.

Here's what kinda worked but they are not the ideal solution:

* If I configure Hyprland to only use my nvidia video card, everything works, vkcube-wayland renders fine, a beta version of godot with wayland works, the performance is excelent, except my embedded monitor does not work, the only visble thing is the tty that never moves or do anything, and most of the time my notebook is not connected to the external monitor.
* Anything X related works fine and in wayland anything that does not require vulkan works, I can compile packages to use only OpenGL, but, vulkan is better overall and I want to move completely to wayland and even develop things with wayland and vulkan.
* Xwayland works perfectly fine regardless if it's vulkan or opengl. Don't ask me why, it just works.
* I can make everything work using only the CPU's embedded GPU... Which of course, the performance goes to hell

using egl-wayland 1.11, 1.12 and 1.13 did nothing.

And I kid you not, vulkaninfo always, always, ended in a segmentation fault, regardless if vkcube-wayland or whatever works, it segfaults at the end.

if I run vkcube-wayland with prime-run, isntead of segmentation fault, I get this error instead:

> Selected GPU 1: NVIDIA GeForce GTX 965M, type: DiscreteGpu
> [destroyed object]: error 7: importing the supplied dmabufs failed

Reproducible: Always

Steps to Reproduce:
1. Have a optimus laptop
2. Try to run 
Actual Results:  
crash

Expected Results:  
spinning cube

>Obs: This was resolved by installing x11-drivers/nvidia-drivers-545.23.06 (beta version)
Are you saying that everything works with 545 and the issue is solved? I don't follow. What's Obs: refering to here? obs-studio? (it's not mentioned anywhere else so I was wondering where this fits in).

This beta has a lot of wayland improvements and changed vulkan handling (no more vulkan-producer helper lib), and supposedly has fixes for offloading on wayland -- so this does not sound too surprising.

Either way, wayland with nvidia is still a pretty experimental thing, even moreso with offloading and there's probably nothing vulkan-tools can do there.

Obs as in observation. And yes, it works with that beta.

I was asked if I could post here by Kangie and immolo to document or see if there were an alternative fix, I believe and we weren't so sure where to post and since I found the issue in vkcube-wayland I thought I could post here.

But feel free to close or move or something.

I can't imagine there is anything wrong with vkcube, especially if a new nvidia driver fixes it, probably there was a problem in their vulkan implementation.
