s are a very nice feature of Linux
. They enable you to have multiple login session
s on one computer without
running X Windows
. You switch to virtual
console number n by pressing Alt and the function
key Fn simultaneously. For
example. Alt-F2 will switch to virtual console 2. Each virtual console can run a separate login session.
Generally virtual consoles 1-6 are text screens, while virtual console 7 is
reserved for xdm
and virtual console 8 for the error messages from xdm. To switch away from virtual console 7, you must
type Ctrl-Alt-Fn rather than just Alt-Fn.
Virtual consoles are particularly useful when you are trying to get X Windows working, especially if you are also having
problems with some commands causing your session to hang - if one virtual console hangs, you can switch to another.
