ubuntu compton如何切换显卡

在Ubuntu系统中，使用Compton作为窗口合成器时，切换显卡通常涉及到更改Compton的配置文件或使用命令行参数来指定要使用的GPU。以下是一些基本步骤，可以帮助你在Ubuntu系统中使用Compton切换显卡：

1. 安装Compton： 如果你还没有安装Compton，可以使用以下命令来安装它：

   sudo apt update
   sudo apt install compton
   

2. 确定可用的GPU： 使用lspci或glxinfo命令来确定你的系统中有多少个GPU以及它们的标识符。

   lspci | grep -i nvidia
   glxinfo | grep "OpenGL renderer"
   

3. 配置Compton： Compton的配置文件通常位于~/.config/compton.conf。你可以创建或编辑这个文件来指定要使用的GPU。例如，如果你想要使用NVIDIA GPU，你可以添加以下配置：

   backend = "glx";
   glx-dri3 = true;
   glx-no-stencil = true;
   glx-copy-from-front = false;
   glx-fbconfig = false;
