我在尝试打开 steam 时遇到错误：
Running Steam on ubuntu 18.04 64-bit

本页上的说明对我有用（Ubuntu 18.04，GTX 1650s）：https://github.com/lutris/docs/blob/master/InstallingDrivers.md
英伟达：
要获取最新的 Nvidia 驱动程序，需要添加专有 GPU 驱动程序 PPA：
sudo add-apt-repository ppa:graphics-drivers/ppa
启用 32 位架构（如果还没有）：
sudo dpkg --add-architecture i386
更新以刷新包：
sudo apt update
警告：安装前请确保您的显卡受 430 驱动程序支持。要查看受支持的 GPU 列表，请单击此处：https://www.nvidia.com/Download/driverResults.aspx/149138/en-us
安装 440.82 驱动程序：
sudo apt install nvidia-driver-440 libnvidia-gl-440 libnvidia-gl-440:i386
安装对 Vulkan API 的支持（仅当您拥有支持 Vulkan 的 GPU 时才有效）：
sudo apt install libvulkan1 libvulkan1:i386
重新启动以应用更改。
答案2
您可能会对此感到惊讶，但此错误通常只是图形驱动程序更新的副作用，导致库和内核模块不同步。解决方法是重新启动计算机并再次启动 Steam。它不止一次帮助了我。
