These are called "virtual" because you -+ can run several virtual terminals (also called virtual consoles) on -+ one physical terminal. This is rather useful, for example one -+ virtual terminal can collect system messages and warnings, another -+ one can be used for a text-mode user session, and a third could run -+ an X session, all in parallel. Switching between virtual terminals -+ is done with certain key combinations, usually Alt-<function key>. -+ -+ The setterm command ("man setterm") can be used to change the -+ properties (such as colors or beeping) of a virtual terminal. The -+ man page console_codes(4) ("man console_codes") contains the special -+ character sequences that can be used to change those properties -+ directly. The fonts used on virtual terminals can be changed with -+ the setfont ("man setfont") command and the key bindings are defined -+ with the loadkeys ("man loadkeys") command. -+ -+ You need at least one virtual terminal device in order to make use -+ of your keyboard and monitor.
