&lt;H2&gt;&lt;A NAME=&quot;s7&quot;&gt;7. Console switching&lt;/A&gt;&lt;/H2&gt;

&lt;P&gt;
&lt;!--
console!switching
--&gt;
&lt;P&gt;By default, console switching is done using Alt-Fn or Ctrl-Alt-Fn.
Under &lt;CODE&gt;X&lt;/CODE&gt; (or recent versions of &lt;CODE&gt;dosemu&lt;/CODE&gt;), only Ctrl-Alt-Fn works.
Many keymaps will allow cyclic walks through all allocated consoles
using Alt-RightArrow and Alt-LeftArrow.
&lt;P&gt;XFree86 1.3 does not know that Alt is down when you switch to the X
window. Thus, you cannot switch immediately to some other VT again
but have to release Alt first.
In the other direction this should work: the kernel always keeps
track of the up/down status of all keys. (As far as possible: on some
keyboards some keys do not emit a scancode when pressed (e.g.: the PFn
keys of a FOCUS 9000) or released (e.g.: the Pause key of many keyboards).)
&lt;P&gt;XFree86 1.3 saves the fonts loaded in the character ROMs when started,
and restores it on a console switch. Thus, the result of &lt;CODE&gt;setfont&lt;/CODE&gt; on
a VT is wiped out when you go to X and back.
Using &lt;CODE&gt;setfont&lt;/CODE&gt; under X will lead to funny results.
&lt;P&gt;One can change VT under program control using the &lt;CODE&gt;chvt&lt;/CODE&gt; command.
&lt;P&gt;
&lt;H2&gt;&lt;A NAME=&quot;ss7.1&quot;&gt;7.1 Changing the number of Virtual Consoles&lt;/A&gt;
&lt;/H2&gt;

&lt;P&gt;
&lt;!--
console!changing number of
--&gt;
&lt;P&gt;This question still comes up from time to time, but the answer is:
you already have enough of them.
Since kernel version 1.1.54, there are between 1 and 63 virtual
consoles. A new one is created as soon as it is opened. It is
removed by the utility &lt;CODE&gt;deallocvt&lt;/CODE&gt; (but it can be removed only when
no processes are associated to it anymore, and no text on it has been
selected by programs like &lt;CODE&gt;selection&lt;/CODE&gt; or &lt;CODE&gt;gpm&lt;/CODE&gt;).
&lt;P&gt;For older kernels, change the line
&lt;BLOCKQUOTE&gt;&lt;CODE&gt;
&lt;PRE&gt;
        #define NR_CONSOLES     8
&lt;/PRE&gt;
&lt;/CODE&gt;&lt;/BLOCKQUOTE&gt;

in &lt;CODE&gt;include/linux/tty.h&lt;/CODE&gt; (don&#039;t increase this number beyond 63),
and recompile the kernel.
&lt;P&gt;If they do not exist yet, create the tty devices with &lt;CODE&gt;MAKEDEV&lt;/CODE&gt;
or &lt;CODE&gt;mknod tty&lt;/CODE&gt;N &lt;CODE&gt;c 4&lt;/CODE&gt; N where N denotes the tty number. For example,
&lt;BLOCKQUOTE&gt;&lt;CODE&gt;
&lt;PRE&gt;
        for i in 9 10 11 12; do mknod /dev/tty$i c 4 $i; done
&lt;/PRE&gt;
&lt;/CODE&gt;&lt;/BLOCKQUOTE&gt;

or, better (since it also takes care of owner and permissions),
&lt;BLOCKQUOTE&gt;&lt;CODE&gt;
&lt;PRE&gt;
        for i in 9 10 11 12; do /dev/MAKEDEV tty$i; done
&lt;/PRE&gt;
&lt;/CODE&gt;&lt;/BLOCKQUOTE&gt;
&lt;P&gt;If you want the new VCs to run &lt;CODE&gt;getty&lt;/CODE&gt;, add lines in &lt;CODE&gt;/etc/inittab&lt;/CODE&gt;.
(But it is much better to have only two &lt;CODE&gt;getty&lt;/CODE&gt;&#039;s running,
and to create more consoles dynamically as the need arises.
That way you&#039;ll have more memory when you don&#039;t use all these consoles,
and also more consoles, in case you really need them.
Edit &lt;CODE&gt;/etc/inittab&lt;/CODE&gt; and comment out all &lt;CODE&gt;getty&lt;/CODE&gt;&#039;s except
for the first two.)
&lt;P&gt;When the consoles are allocated dynamically, it is usually easiest
to have only one or two running &lt;CODE&gt;getty&lt;/CODE&gt;. More are opened by
&lt;CODE&gt;open -l -s bash&lt;/CODE&gt;. Unused consoles (without associated processes)
are deallocated using &lt;CODE&gt;deallocvt&lt;/CODE&gt; (formerly &lt;CODE&gt;disalloc&lt;/CODE&gt;).
But, you say, I am involved in activities when I suddenly need more
consoles, and do not have a bash prompt available to give the &lt;CODE&gt;open&lt;/CODE&gt;
command.
Fortunately it is possible to create a new console upon a single
keystroke, regardless of what is happening at the current console.
&lt;P&gt;If you have &lt;CODE&gt;spawn_login&lt;/CODE&gt; from &lt;CODE&gt;kbd-1.04.tar.gz&lt;/CODE&gt; and you put
&lt;BLOCKQUOTE&gt;&lt;CODE&gt;
&lt;PRE&gt;
        loadkeys &amp;lt;&amp;lt; EOF
        alt keycode 103 = Spawn_Console
        EOF
        spawn_login &amp;amp;
&lt;/PRE&gt;
&lt;/CODE&gt;&lt;/BLOCKQUOTE&gt;

in &lt;CODE&gt;/etc/rc.local&lt;/CODE&gt;, then typing Alt-UpArrow will create a fresh VC
running &lt;CODE&gt;login&lt;/CODE&gt; (and switch to it). With &lt;CODE&gt;spawn_console &amp;amp;&lt;/CODE&gt; instead of
&lt;CODE&gt;spawn_login &amp;amp;&lt;/CODE&gt; you&#039;ll have bash running there.
See also &lt;CODE&gt;open-1.4.tgz&lt;/CODE&gt; and &lt;CODE&gt;dynamic-vc-1.1.tar.gz&lt;/CODE&gt;.
&lt;P&gt;What action should be taken upon this Spawn_Console keypress
can also be set in &lt;CODE&gt;/etc/inittab&lt;/CODE&gt; under &lt;CODE&gt;kbrequest&lt;/CODE&gt;,
if you have a recent &lt;CODE&gt;init&lt;/CODE&gt;. See inittab(5).
&lt;P&gt;(This action can be something entirely different - I just called
the key Spawn_Console because that is what I used it for.
When used for other purposes it is less confusing to use
its synonym KeyboardSignal.
For example, some people like to put the lines
&lt;BLOCKQUOTE&gt;&lt;CODE&gt;
&lt;PRE&gt;
        kb::kbrequest:/sbin/shutdown -h now
&lt;/PRE&gt;
&lt;/CODE&gt;&lt;/BLOCKQUOTE&gt;

in &lt;CODE&gt;/etc/inittab&lt;/CODE&gt;, and
&lt;BLOCKQUOTE&gt;&lt;CODE&gt;
&lt;PRE&gt;
        control alt keycode 79 = KeyboardSignal
        control alt keycode 107 = KeyboardSignal
&lt;/PRE&gt;
&lt;/CODE&gt;&lt;/BLOCKQUOTE&gt;

in their keymap. Now Ctrl-Alt-End will do a system shutdown.)
&lt;P&gt;You can only login as &quot;root&quot; on terminals listed in &lt;CODE&gt;/etc/securetty&lt;/CODE&gt;.
There exist programs that read terminal settings from files
&lt;CODE&gt;/etc/ttys&lt;/CODE&gt; and &lt;CODE&gt;/etc/ttytype&lt;/CODE&gt;. If you have such
files, and create additional consoles, then it might be a good idea
to also add entries for them in these files.
