I am trying to launch Unreal Engine 5 on Ubuntu 22
The message I receive is: Cannot find a compatible Vulkan Device.
On my terminal I can run vkcube to see a cube from Vulkan.
Is there someway to configure Unreal Engine 5 on launch time to fix this problem?
same situation here with UE 5.2.
Did you solve this?
I am having same issue of UE 5.2 crashing on Linux. I am getting a few errors although the cube worked and I did get this: uid@machinename:~/UnrealEngine/Engine/Binaries/Linux$ vkcube
MESA-INTEL: warning: Haswell Vulkan support is incomplete
uid@machinename:~/UnrealEngine/Engine/Binaries/Linux$
Hope this sheds some light.
Don’t know if anyone else has encountered this.
Spent a few hours trying to figure this out, Googling around. Tried all sorts of things, like installing a command line Nvidia driver, manually installing and configuring kernels, etc.
What ended up working, was to install the linux kernel headers from apt and then rebooting.
sudo apt install linux-headers-$(uname -r)
Hope this helps!
Goto your project config and edit the default editor ini. Change “+TargetedRHIs=SF_VULKAN_SM6” to “+TargetedRHIs=SF_VULKAN_SM5”.
Thank you so much for this comment. May I ask you why this fixes it? I am new to both linux and Unreal Engine 5 and experienced the same issue and am trying to learn from this but google isn’t being very helpful.
