在ubuntu上运行Vulkan失败

Question

github SaschaWillems/Vulkan上的代码在使用非常老的GPU GT730的WIN10上运行得很流畅，但是当我想在ubuntu上运行它时，我遇到了很多问题。以下是我的系统简介:操作系统|Ubuntu16.04.5LTS显卡|SDKGTX1080驱动程序| 430.50 GeForce版本| 1.1.121.0，但当我运行Vulkan时，它将返回ERROR_INITIALIZATION_FAILED。

所以我按照lunarg网站上的"Getting Started with the Vulkan SDK"指南，首先安装了vulkan-sdk：

      wget -qO - http://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo apt-key add -
      sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-xenial.list http://packages.lunarg.com/vulkan/lunarg-vulkan-xenial.list
      sudo apt update
      sudo apt install vulkan-sdk

然后我运行vkvia，返回的错误显示"Vulkan找不到兼容的驱动程序“，所以我按照文档找到了"Vulkan Graphics Driver Problems"。医生说可能有4种原因：

     1. hardware not support Vulkan. but i found on nvidia website GEDORCE GTX 1080 is OK for vulkan1.1
     2. driver not support Vulkan. but i found on nvidia website driver 430.50 is OK for vulkan1.1
     3. no Vulkan driver with support for the OS. i am running on ubuntu 16.04.5 LTS, 
     4. driver failed to install properly. But i can use nvidia-smi to show the card, and i can run my other code on this GPU without VULKAN

如果我运行VK_ERROR_INITIALIZATION_FAILED，错误信息是vulkaninfo.c:6155: failed with

希望有人能帮助我！谢谢!

Answer 1

试试这个：

sudo apt-get install libvulkan1 libvulkan1:i386 mesa-vulkan-drivers mesa-vulkan-drivers:i386

您可以使用vulkan工具进行测试：

sudo apt-get install vulkan-tools
vulkan-cube
