Vulkan-Loader VS display-drivers-uninstaller

Take a look at Vulkan Loader Debugging, try running vulkaninfo with set VK_LOADER_DEBUG=all.

probably not given this response from 2021 https://github.com/KhronosGroup/Vulkan-Loader/issues/536

Every program that needs Vulkan does indeed link against and call something with a well-known, long-time stable ABI. This is normally Vulkan-Loader, which provides libvulkan. For OpenGL, libglvnd is a nearly equivalent library that fulfills largely the same function and provides libGL/libGLES/etc.

I'm reading through the official docs before I start a tutorial. The docs mention the loader but not very often. It does link to the loader's docs on github. I've read most of that. I still don't understand if it's an integral part of the API or just a tooling for certain use cases (multiple drivers, complex validation, etc.). I also listened to a webinar about the loader and the speaker claims he is the owner of the loader. That made me even more confused. Can someone please fill me in? Do all Vulkan apps interface with the loader before the driver? Thanks.

It's from here: https://github.com/KhronosGroup/Vulkan-Loader/blob/393e23f91d21ce117c19e8c42e084477c3a25c7c/tests/framework/test_util.h

Not exactly sure, but what you describe seems similar to the issue https://github.com/KhronosGroup/Vulkan-Loader/issues/776 .

This would be good to read to understand why some of the things are the way they are. https://github.com/KhronosGroup/Vulkan-Loader/blob/master/docs/LoaderApplicationInterface.md

I DDU'd the drivers and tried again with similar results. I also tried an old Radeon HD 2400 PRO and on that card I could not even get drivers to install.

Além de verificares que o monitor está efetivamente ligado à placa gráfica e não à placa integrada da tua motherboard (já agora, desligá-la nas opções da BIOS), já experimentaste desinstalar por completo os drivers NVIDIA e instalar novamente? Para limpar eficazmente, recomendo o DDU (Display Driver Uninstaller).

DDU Download: Source 1 or Source 2

Try running a DDU driver uninstall (www.wagnardsoft.com) , reinstall your latest video drives and see what that gets you.

In Windows make sure you use DDU from https://www.wagnardsoft.com/ or https://www.guru3d.com/files-details/display-driver-uninstaller-download.html

You might want to use something like Display Driver Uninstaller / Cleaner to more completely clean off all driver versions, rebooting at least once as directed, and then manually download the correct driver from NVIDIA and install it.
