Issue in execution of samples

[BenLag2906]

Hi All,

After compiling VulKan, I launch the following command line :
./vulkan_samples sample swapchain_images

I obtain the following prompt :

" Logger initialized

Could you please provide a piece of advise ? to execute samples( for all samples this kind of error is thrown)

Best regards.

It loks like you have multiple GPUs installed, including llvmppipe. Is this a notebook with integrated and discrete graphics?

[BenLag2906]

Hi,
As described in previous message i have only one GPU : NVIDIA GeForce RTX 3060 Laptop GPU on Linux compilation

it's not a notebook, it's my command line in execution of samples. ( screen in attached file )

Your screenshot says different. It lists three Vulkan capabale implementations in your setup:

[info] Found GPU: Intel(R) Graphics (ADL GT2)
[info] Found GPU: NVIDIA GeForce RTX 3060 Laptop GPU
[info] Found GPU: llvmpipe (LLVM 15.0.7, 256 bits)

It's possible that one of these is interferring (I'd guess llvm), so removing them might help.

Yes, thanks for your answer
but only one is selected,

Selected GPU: NVIDIA GeForce RTX 3060 Laptop GPU.

How can i remove this false detection of intel or llvmpipe ?

thanks in advance

This might also be related to the hybrid graphics in your Laptop. Can you check if the integrated Intel GPU is actually disabled? The sample not being able to create the swap chain sounds like it wants to use the wrong GPU for presentation.

If it's actually disabled, try explicitly selecting the gpu using the --gpu argument like this:

 .\vulkan_samples sample hello_triangle --gpu 1

If that doesn't help, please run vkvia from the Vulkan SDK and attach it's ouput so we can check your installation.
