Crash on startup with Linux + Vulkan + offscreen rendering

I’m reposting the problem I reported on the rendering subforum, since this seems like a more appropriate place. I’ll start going through the context creation code myself, but was hoping someone from Epic would already be familiar with this issue.

I’m working on being able to do data capture in a compute cluster, which means that I need to get offscreen rendering to work under Linux. To test it out, I created a simple sequencer for the StarterContent that is bundled with the engine. The following works as expected:

Engine/Binaries/Linux/UE4Editor /home/efagerholm/ue4/UnrealEngine/Samples/StarterContent/StarterContent.uproject -game -MovieSceneCaptureType="/Script/MovieSceneCapture.AutomatedLevelSequenceCapture" -LevelSequence="/Game/Sequence" -MovieFolder="/home/efagerholm/ue4/output/" -NoLoadingScreen -MovieFormat=JPG -MovieQuality=100 -ResX=1920 -ResY=1080 -vulkan

However, if I add the -RenderOffscreen flag, then I get a segfault. My setup is Ubuntu 18.04 with two TITAN V GPUs and NVIDIA 440.44 drivers. The output from the game when it crashes can be found below:



efagerholm@efagerholm:~/ue4/UnrealEngine$ Engine/Binaries/Linux/UE4Editor /home/efagerholm/ue4/UnrealEngine/Samples/StarterContent/StarterContent.uproject -game -MovieSceneCaptureType="/Script/MovieSceneCapture.AutomatedLevelSequenceCapture" -LevelSequence="/Game/Sequence" -MovieFolder="/home/efagerholm/ue4/output/" -NoLoadingScreen -MovieFormat=JPG -MovieQuality=100 -ResX=1920 -ResY=1080 -vulkan -RenderOffscreen
Increasing per-process limit of core file size to infinity.

The line from your log:

Should indicate the SDL error but the error string is the wrong one. It should be the output of SDL_GetError() converted to utf-16.

In method


FVulkanLinuxPlatform::CreateSurface

in


UnrealEngine/Engine/Source/Runtime/VulkanRHI/Private/Linux/VulkanLinuxPlatform.cpp

try wrapping the call to


SDL_GetError()

as


*FString(SDL_GetError())

This won’t fix the problem, but it might lead you to where it is.

I’d be interested to know what the problem ends up being.

i have a similar problem on startup

i’m following this thread. hope someone managed to fix it.
i was moving from windows 10 pro to linux mint and i have a project that should be released on 1st of may so theres no time to download an older version and compile it especially with slow net 120kbps

I’ve been running on Linux with -opengl4 option to UE4Editor because Vulkan would not work for me.

Yesterday I upgraded to 4.25 and thought I’d give this a try. By co-incidence I happened to have my Engine Scalability Settings in my project down to Low.

Lo and behold Vulkan at low resolution works just fine.

I tried increasing the Engine Scalability Settings but every time the engine would crash.

So the bottom line is that the Vulkan driver on a GTX 950 with 2GB cannot handle a 4K monitor on anything other than low res.
