Unreal Engine 4 : 'Unable to initialize Vulkan'

snap
1

After sapping some Unreal Engine 4 games with success, I noticed that some games (the latest ones I think) can not run because of this issue:

First window: ‘Unable to initialize Vulkan. Unable to load Vulkan library and/or acquire the necessary function pointers. Make sure and up-to-date libvulkan.so.1 is installed. ’ Second window: ‘Failed to load Vulkan Driver which is required to run the engine. The engine no longer fallbacks to OpenGL4 which has been deprecated. ’* Then nothing happen.

Note: my Ubuntu 24.04 computer has a Nvidia Geforce RTX 3060 GPU, with Nvidia driver v550. The problem is the same when I make use of code from https://snapcraft.io/docs/gpu-support

Is this a known issue ?

The information in that page isn’t wrong; but it’s entirely unnecessary if you’re using e.g., the gnome extension, which should handle configuration of GPU drivers, audio, etc - for you. It’s worth noting though that whilst snaps can bundle Mesa (and the Gnome extension will handle this for you entirely transparently), NVidia drivers are always pulled from the host and your users may then have differing results based on driver variation from the host, rather than the snap.
