can not launch LGSVL

[201520906050]

when i clicked the icon to launch LGSVL, it appeared for just half second and the suddenly disappeared. And I tried to launch it by command ./simulator,and the output is:

Set current directory to /home/pami/svlsimulator-linux64-2021.1 Found path: /home/pami/svlsimulator-linux64-2021.1/simulator

So I checked the log in~/.config/unity3d/LG Silicon Valley Lab/LGSVL Simulator/Player.log , and the output is:

Mono path[0] = '/home/pami/Downloads/lgsvlsimulator-linux64-2020.06/simulator_Data/Managed' Mono config path = '/home/pami/Downloads/lgsvlsimulator-linux64-2020.06/simulator_Data/MonoBleedingEdge/etc' Preloaded 'liblaszip.so' Preloaded 'libpng.so' Preloaded 'libsqlite3.so' Preloaded 'libturbojpeg.so' Display 0 'C27R502 27"': 1920x1080 (primary device).

I also typed vulkaninfo in terminal, errors like that:

ERROR: [Loader Message] Code 0 : loader_scanned_icd_add: Could not get 'vkCreateInstance' via 'vk_icdGetInstanceProcAddr' for ICD libGLX_nvidia.so.0 ERROR: [Loader Message] Code 0 : /usr/lib/i386-linux-gnu/libvulkan_intel.so: wrong ELF class: ELFCLASS32 ERROR: [Loader Message] Code 0 : /usr/lib/i386-linux-gnu/libvulkan_radeon.so: wrong ELF class: ELFCLASS32 Cannot create Vulkan instance. This problem is often caused by a faulty installation of the Vulkan driver or attempting to use a GPU that does not support Vulkan. /build/vulkan-tools-136mCR/vulkan-tools-1.1.126.0+dfsg1/vulkaninfo/vulkaninfo.h:297: failed with ERROR_INCOMPATIBLE_DRIVER

the cpu is AMD® Ryzen 7 5800x 8-core processor × 16 , GPU is Nvidia GeForce GTX 1080Ti, driver version is 510.54

Looking forward to your reply for handling the urgent issue ! Thank u !

Looks like you have not installed the VulkanSDK correctly. The instructions are on the docs here: https://www.svlsimulator.com/docs/installation-guide/installing-simulator/ Under the section Vulkan drivers. Hope that helps.

Hello, but i have already installed VulkanSDK through the instuctions and the output was like that: (base) pami@pami:~/svlsimulator-linux64-2021.1$ sudo apt install libvulkan1 Reading package lists... Done Building dependency tree Reading state information... Done libvulkan1 is already the newest version (1.1.126.0-2~gpu18.04.1). 0 upgraded, 0 newly installed, 0 to remove and 208 not upgraded. (base) pami@pami:~/svlsimulator-linux64-2021.1$ sudo apt remove mesa-vulkan-drivers Reading package lists... Done Building dependency tree Reading state information... Done Package 'mesa-vulkan-drivers' is not installed, so not removed. Did you mean 'mesa-vulkan-drivers:i386'? 0 upgraded, 0 newly installed, 0 to remove and 208 not upgraded.

i tried this several times and none of them worked , so confused

It says at the bottom of that message "Vulcan drivers not installed so not removed" which sounds like the driver was never installed correctly to begin with. I would look at the Vulcan support pages.
