我在 Ubuntu 16.04 上，配备 AMD Radeon R9 390 gpu。图形驱动程序：AMD gpu-pro 17.10（最新驱动程序是 17.40）
我之前安装过 Vulkan。但每当我尝试安装新版本时，它都不会更新。
我刚刚下载并安装了 LunarG Vulkan sdk 1.0.61.1
但是当我提示“vulkaninfo”时，我得到以下信息：
Vulkan API Version: 1.0.42
INFO: [loader] Code 0 : Found manifest file /home/simon/.local/share/vulkan/implicit_layer.d/steamoverlay_i386.json, version "1.0.0"

为什么它说 1.0.42 - 我从来没有下载过该版本。
我尝试了几次并尝试卸载。遵循以下两个指南：

答案1
您的环境变量~/.bashrc可能未设置。以下是它们对于 SDK 1.0.65.0 的工作方式：
export VULKAN_SDK=~/Downloads/VulkanSDK/1.0.65.0/x86_64
export PATH=$VULKAN_SDK/bin:$PATH
export LD_LIBRARY_PATH=$VULKAN_SDK/lib:$LD_LIBRARY_PATH
export VK_LAYER_PATH=$VULKAN_SDK/etc/explicit_layer.d
添加这些行后，重新启动终端并vulkaninfo再次运行。
