Question

我想在我的Linux Ubuntu 16.04机器上设置Vulkan API，但它不起作用。我按照＆＃34;入门＆＃34;准确。

当我尝试运行vulkaninfo时，我得到了这个：

VULKAN INFO

Vulkan API Version: 1.0.37

Instance Extensions:
====================
Instance Extensions count = 4
    VK_KHR_surface                      : extension revision 25
    VK_KHR_xcb_surface                  : extension revision  6

当我尝试启动立方体时，我得到了这个：

cube: /home/adrian/vulkan/VulkanSDK/1.0.37.0/examples/cube.c:2789: demo_init_vk: Assertion `!err && gpu_count > 0' failed.
Abgebrochen (Speicherabzug geschrieben)

最后一条消息表示＆＃34; Aborted＆＃34;然后在括号中＆＃34;核心转储＆＃34;

我正确设置了环境变量：

export PATH=$HOME/vulkan/VulkanSDK/1.0.37.0/x86_64/bin
export LD_LIBRARY_PATH=$HOME/vulkan/VulkanSDK/1.0.37.0/x86_64/lib
export VK_LAYER_PATH=$HOME/vulkan/VulkanSDK/1.0.37.0/x86_64/etc/explicit_layer.d

我有Nvidia Geforce GT 730和支持Vulkan的367.57驱动程序

任何人都可以帮助我吗？

Answer 1

作为Vulkan SDK的一部分，包含了Vulkan安装分析器（VIA）。运行此工具以完整分析您的安装。如果您不了解输出，请在LunarXchange（vulkan.lunarg.com）上提交您的VIA输出作为问题，LunarG工程师将为您提供帮助。您可以在此处找到有关如何在SDK安装中运行VIA的文档，或者在LunarXchange上查看它：https://vulkan.lunarg.com/doc/sdk/1.0.37.0/windows/via.html

Answer 2

在Linux发行版上，如果我安装假/垫片驱动程序（例如，在禁用iGPU时使用Mesa Intel或在我的GPU仍然不受支持的情况下使用Mesa RADV），这就会发生。
