How to access the command interface when encountering a black screen on Linux.
If you encounter a black screen and can’t enter the graphical interface in the Linux system, you can try the following methods to enter the command line interface:
- Press the Ctrl+Alt+F1 (or F2 to F6) key combination to switch to the virtual terminal interface. This will open a command line interface where you can enter your username and password to log in to the system.
- If you are unable to open the virtual terminal, you can try entering recovery mode. Press the Shift key (or Esc key) during startup, then choose to enter recovery mode. In recovery mode, you can select to enter the command line interface for troubleshooting and repair.
- If the above methods do not work, you can try using a Live CD or USB to boot the system, then mount the hard drive partition and enter the command-line interface of the system for repair.
It is important to note that, after entering the command interface, you may need to troubleshoot and fix system issues such as restarting the X window system, updating graphics card drivers, or repairing damaged system files. If unsure how to proceed, it is recommended to consult relevant Linux system troubleshooting documents or seek assistance from professional technicians.
