How can I access the graphic interface after I change the graphics card driver of Ubuntu?

In the "additional driver" option under Ubuntu system settings, You can see several optional drivers. If you are curious, you have changed the current driver and need to restart after installation. After startup, you can only access the command line interface.

After comprehensive search, it is determined that the driver installation does not match. The final solution is quite simple. The method is as follows:

Run commands

Sudo RM/etc/X11/Xorg. confsudo reboot # restart

The first line is to delete the Xorg. conf file. The Xorg. conf file stores various information about X Windows. When entering the X interface, you need to read the relevant settings from here. However, after we delete it, X will use the default VESA driver after restart. The compatibility with this VESA driver is good, at least it can ensure that you can enter the X interface. After entering the graphic interface, install the recommended and normal drivers in the additional driver options and restart them. OK. That's simple.
