Ubuntu18.04LTS左上角光标闪烁原因之一:NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver.


1.Ubuntu18.04在安装lightdm之后重启后出现黑屏,光标左上角闪烁

2.nvidia-smi显示NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

3.重装显卡驱动然后重新进入桌面就行了

sudo sh NVIDIA-Linux-x86_64-440.100.run

 

 

 

 

 

 

 

 

完成重装后成功解决

最后重新进入图形界面即可

sudo init 3

sudo init 5

 

注:如果无法自动远程连接上ubuntu系统,可以通过ubuntu grub进入recover mode,在recover menu中选择root:Drop to root shell prompt,然后通过shell命令运行显卡驱动程序,重装显卡驱动
