建议上nvidia官网下载对应显卡型号的驱动

什么版本的系统

deepin安装N卡，建议走无图形化安装(在图形化安装会出现安装失败问题)

1、先去官网下载相应的安装包，下载在本地改个简单的名称

2、把下载在本地安装包授权执行权限

3、参考https://blog.csdn.net/qq_37151416/article/details/107975417的第5步开始

4、安装完后先重启

下载量对应驱动的.run文件，还是无法安装

The NVIDIA driver appears to have been installed previously using a different installer. To prevent potential conflicts, it is recommended either to update the existing installation using the same mechanism by which it was originally installed, or to uninstall the existing installation before installing this driver.

NVIDIA 驱动程序似乎是之前使用不同的安装程序安装的。为了防止潜在的冲突，建议使用与最初安装时相同的机制更新现有安装，或者在安装此驱动程序之前卸载现有安装。
