@juancarlospaco this is easily done on your own system, not in a PKGBUILD, given that building packages runs as root:

sudo groupadd unrealengine-users
sudo usermod -aG unrealengine-users (your-username)
sudo chown -R root:unrealengine-users /opt/unreal-engine
sudo chmod -R 775 /opt/unreal-engine

Permission issues like this are already mentioned on the UE Arch wiki page: https://wiki.archlinux.org/title/Unreal_Engine_4#Installing_from_the_AUR

This is a user system problem; I already did what I could without needing users to do the above by giving the 777 permissions. If it still gives you trouble, you'll have to use the example to solve it or change the install location to somewhere you have user permissions by default (as I cannot do this for you).

@acxz, You have 940MX, but you use the integrated Intel graphics. Try Optimus Manager to set up discrete graphics.

This is the output:

server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
OpenGL vendor string: Intel Open Source Technology Center

Welp, I guess I need it to use my NVIDIA GPU. Let me try something. EDIT: Okay now I am getting this:

server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation

@acxz, could you show me glxinfo | grep vendor?

I still receive the error with vulkan-icd-loader installed. Also installed spirv-tools on top of that and still get the same error.

@acxz, I think you need to comment out Vulkan also in the same section to launch the engine in OpenGL mode. I have the following Vulkan-related packages installed: vulkan-icd-loader, spirv-tools. Could you install these packages one by one to let us know which one is needed to work?

@Shatur p sure, its a 940MX. Still getting the same error after the uncomment.

Shatur commented on 2020-01-26 16:50 (UTC)

@acxz, are you sure your graphics card supports Vulkan? You can open the unreal-engine/Engine/Config/BaseEngine.ini file and uncomment + TargetedRHIs = GLSL_430.

Hey guys, Unreal finally installed for me (such a beast). BUt when trying to launch /opt/unreal-engine/Engine/Binaries/Linux/UE4Editor I get the following error on a popup dialog:

Cannot find a compatible Vulkan device or driver. Try updating your video driver to a more recent version and make sure your video card supports Vulkan.

I have nvidia-utils installed, do I need a specific vulkan package?

I can run the other exe, /opt/unreal-engine/Engine/Binaries/Linux/UnrealFrontend

@zerophase, sorry I already deleted it :(

@shatur What happens in the logs when the engine crashes for you?
