ctrl + alt + F10

ctrl + alt + F2

 

<Ctrl> <Alt> <F1> Switch to the first text terminal. You can have up to six different terminals under 7a686964616fe59b9ee7ad9431333363376463Linux. The meaning of this command is: "Hold down the <Ctrl> key and <Alt> key at the same time, then press the <F1> key, and then release all the keys."
<Ctrl> <Alt> <Fn> (n = 1..6): Switch to the nth text terminal. (You can also use the command chvt n which is not very often used, n refers to the nth text terminal). Under the text terminal (not in the X window), you can also simply use <ALT> <Fn> to switch, without the <CTRL> key. Print out the name of the terminal you are using. If you want to know the name of the terminal, you can use the command fgconsole.
<Ctrl> <Alt> <F7>: Switch to the first graphical user interface (generally X-window on the seventh terminal)
<Ctrl> <Alt> <Fn> (n = 7 to 12): switch to Nth graphical user street. By default, the first X-Window runs on the seventh terminal, and there is nothing from the eighth to the twelfth. Of course, you can start these graphical user interfaces one by one. <Tab>: (under the text terminal) You can use TAB to automatically complete commands or display all available options. This shortcut is really easy to use, and you will find it saves you a lot of time if you use it frequently.
