The boot interface of ubuntu20.04 is black, only one cursor is blinking

Next, I will send out my solution completely, because I am also very desperate, and finally solved the problem through continuous attempts

First of all, the boot interface is this thing, and it has been stuck here. The reason is that the memory is used up, and the graphical interface cannot be loaded. Solution: 1. Restart the virtual

machine
, pay attention to press ctrl continuously after restart +alt+f3, because the mouse will pop up, so you have to keep clicking the mouse with your hands, here everyone find their own way, remember to keep pressing

2. The performance of success is that there is a login: then enter the user name and password.

3. After success, it is equivalent to a terminal, here you must first enter su to enter the root authority

4. Enter startx again to force to enter the graphical interface, find any application program in the upper right corner settings, and then click to open it in the software (at this time, the terminal cannot be opened), and then it will display that the content space is insufficient, and then Just open some things, right click to open the location of the file,

See if the third line is 100%, if it is, then this is the problem (I have expanded the capacity here)
