You appear to be running an X server； please exit X before installing. For further details, please

This error message is typically encountered when trying to install certain software packages on a Linux distribution while running an X server. The X server is a software component responsible for managing graphical user interfaces in Linux.

To resolve this issue, you will need to exit the X server before attempting to install the software package. To do so, you can try switching to a different virtual console by pressing Ctrl+Alt+F1 (or F2, F3, etc.) and logging in as the root user or a user with administrative privileges. From there, you can stop the X server by running the following command:

sudo systemctl stop display-manager

This command will stop the display manager, which is responsible for starting the X server. Once the display manager is stopped, you should be able to install the software package without encountering the error message.

After the installation is complete, you can restart the display manager by running the following command:

sudo systemctl start display-manager

This will start the display manager and the X server, allowing you to log back in to your graphical desktop environment.

安装NVIDIA的驱动时，有报错：ERROR： You appear to be running an X server

这个错误通常是由于正在运行的 X 服务器阻止了 NVIDIA 驱动程序的安装。为了解决这个问题，您可以尝试在安装 NVIDIA 驱动程序之前停止 X 服务器。

您可以通过以下命令停止 X 服务器：

sudo service lightdm stop

或者

sudo service gdm stop

如果您使用的是其他的显示管理器，可以替换相应的服务名称。

停止 X 服务器后，您可以重新运行 NVIDIA 驱动程序的安装程序。

安装完成后，您可以使用以下命令重新启动 X 服务器：

sudo service lightdm start

或者

sudo service gdm start

同样地，如果您使用的是其他的显示管理器，可以替换相应的服务名称。
