gtx1650ti 显卡驱动的重装。
- UltraISO制作U盘启动盘， 在ubuntu官网下的20.04TLS版本。
- 插上U盘重启按F2， 选择U盘启动，安装Ubuntu系统。
- 重装显卡驱动。

在下面连接下载驱动，链接中有说适合什么显卡。

修改下载后的文件:
NVIDIA-Linux-x86_64-465.31.run，添加可执行权限。然后运行。chmod +x NVIDIA-Linux-x86_64-465.31.run su root ./NVIDIA-Linux-x86_64-465.31.run -
安装成功后，会出现无法调节亮度的情况。需要修改
/etc/X11/xorg.conf文件，具体修改如下：把其中如下内容 Section "Device" Identifier "Default Device" Driver "nvidia" Option "NoLogo" "True" EndSection 改成 Section "Device" Identifier "Default Device" Driver "nvidia" Option "RegistryDwords" "EnableBrightnessControl=1" EndSection 即添加 Option "RegistryDwords" "EnableBrightnessControl=1" 重启系统，基本可以修改亮度了。

最后运行
nvidia-smi查看是否安装成功。类似下面的信息，表示安装成功。Sat Jun 19 00:02:09 2021 +-----------------------------------------------------------------------------+ | NVIDIA-SMI 465.31 Driver Version: 465.31 CUDA Version: 11.3 | |-------------------------------+----------------------+----------------------+ | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.

如果提示如下错误
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running可以做如下尝试：
sudo apt-get install dkms //重新安装显卡驱动 ./NVIDIA-Linux-x86_64-465.31.run
