Cannot find a compatible Vulkan device or driver - Unreal Engine
8,739
A way I found in order to avoid this issue and work with the Unreal Editor without messing around with graphic drivers (I am on open source drivers shipped with Linux Mint) is to launch the editor with the opengl4 flag. In this way the Vulkan requirement is skipped and the editor can start properly. Using the terminal reach the linux binaries folder ~/UnrealEngine/Engine/Binaries/Linux
and then use this code in order to launch the editor under Opengl4 ./UE4Editor -opengl4

What I tried:
- Tried using Nouveau
- Tried installing NVIDIA drivers using Zypper
- Installed NVIDIA proprietary drivers (and uninstalled Nouveau)
I was really hoping that the proprietary drivers would fix this, but it didn't. I got the drivers from https://developer.nvidia.com/vulkan-driver.
This is the error I keep getting:

Nazzareno about 5 yearsTo run the second one yes, you need to be in the binaries directory because the code is just looking for the UE4Editor executable in order to launch it. There could be some more cleaver way to do it, but I am new to Linux and I am learning step by step how to deal with it and use needed software on it :)

Scott - Слава Україні about 5 yearsThe normal thing to do would be to type
~/UnrealEngine/Engine/Binaries/Linux/UE4Editor -opengl4
from wherever you are. -
