CentOS minimal 版安装图形界面的步骤是怎样的

CentOS minimal 版是一个非常轻量级的 Linux 发行版，主要用于服务器环境，由于其体积小、性能高，很多开发者和系统管理员喜欢使用它，CentOS minimal 版默认没有图形界面，这对于一些需要操作图形界面的用户来说可能会感到不便，本文将介绍如何在 CentOS minimal 版上安装图形界面。

安装 GNOME 桌面环境

1、确保系统已经更新到最新版本：

sudo yum update

2、安装 GNOME 桌面环境所需的软件包：

sudo yum groupinstall "GNOME Desktop" "Graphical Administration Tools"

3、设置系统默认的运行级别为图形界面：

sudo systemctl set-default graphical.target

4、重启系统使设置生效：

sudo reboot

5、在登录界面，选择 "System boot" > "Automatic login",然后输入用户名和密码登录，登录成功后，系统会自动进入桌面环境。

配置显示效果和主题

1、安装 GNOME Tweaks 工具：

sudo yum install gnome-tweaks

2、运行 GNOME Tweaks,对显示效果进行调整，例如调整分辨率、字体大小等。

3、安装 GNOME Control Center(如果尚未安装):

sudo yum install gnome-control-center

4、点击屏幕右上角的电源图标，选择 "Preferences",在弹出的窗口中可以对显示器进行更多设置。

1、如何切换回命令行界面？

答：在登录界面，选择 "System boot" > "Manual",然后输入用户名和密码登录，登录成功后，点击屏幕左下角的 "Applications",选择 "System tools",点击 "Terminal" 即可进入命令行界面，下次启动时，系统会自动恢复到图形界面。

2、如何卸载 GNOME desktop?

答：打开终端，输入以下命令卸载 GNOME Desktop:
