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
