Recently, after installing NVIDIA graphics card on Ubuntu 18.4, it seems that the graphics card is not fully compatible

The first time there was a problem, it was found that the system adopted the default graphics card driver after logging in the account, but the installed graphics card driver was damaged and could not be used

The second time there was a problem, the words/dev/sda2 clean and/dev/sda2 recovering journal appeared on the interface after boot, and they were stuck

For the second problem, the solutions are as follows:

1. In the stuck interface, we need to switch to the command line mode, Ctrl + Alt + F3 (related to the machine, probably between F1 and F6)

2. Check whether the driver of the graphics card has been damaged. Cat/Pro/driver/NVIDIA/version, if not, it means there is a problem

3. Uninstall the installed graphics driver:

sudo apt purge nvidia-*

　sudo apt autoremove

4. Download the corresponding graphics card driver on the official website at: https://www.nvidia.com/Download/index.aspx After selecting the corresponding graphics driver, the downloaded file name is nvidia-linux-x86_ 64-390.77.run

5. Install graphics driver: sudo bashnvidia-linux-x86_ 64-390.77.run
