GPU驱动：An alternate method of installing the NVIDIA driver was detected

An alternate method of installing the NVIDIA driver was detected. (This is usually a package provided by your distributor.) A driver installed via that method may integrate better with your system than a driver installed by nvidia-installer. Please review the message provided by the maintainer of this alternate installation method and decide how to proceed: Continue installation Abort installation The NVIDIA driver provided by Ubuntu can be installed by launching the "Software & Updates" application, and by selecting the NVIDIA driver from the "Additional Drivers" tab.

说明系统检测到你已经通过 Ubuntu 的软件源（apt）装过 NVIDIA 驱动。而你现在又在用 NVIDIA 官方的 .run 安装器（nvidia-installer）尝试安装另一个驱动。

如果依然想用run安装，那就清除apt安装的驱动：

sudo apt purge nvidia-*
