问题描述
我想正确安装 nvidia GPU 驱动程序。nvidia-smi 运行良好，但 vulkaninfo 不行，因为 Segmentation fault (core dumped)。
详情如下：
我的环境：
操作系统：Ubuntu 18.04
GTX：GeForce RTX 3090
NVIDIA 驱动程序：460.73.01
nvidia-smi 的输出如下：
+-----------------------------------------------------------------------------+

Segmentation fault (core dumped)
我认为 vulkaninfo Segmentation fault (core dumped) 的最后一部分有问题。
我该如何调试？
我已经完成了以下命令或程序：sudo apt install libvulkan1sudo apt remove mesa-vulkan-drivers
多次重装GPU驱动。
感谢您的合作。
解决方法
vulkaninfo 错误 iter() 的原因是 xrdp 应用程序，它是远程桌面应用程序，它是 Windows 操作系统上默认安装的应用程序。
xrdp 从 Ubuntu PC 上的原始渲染进行了另一次渲染。
我通过将远程桌面应用程序从 xrdp 更改为不使用其他渲染的 vnc 解决了这个问题。
