14 | <para>In this section we will configure the <command>console</command>
|
---|
15 | initscript that sets up the keyboard
|
---|
16 | map and the console font. If you are a native English speaker so that you
|
---|
17 | don't need to use any non-ASCII characters, and your keyboard is a US one,
|
---|
18 | skip this section. Without the configuration file,
|
---|
19 | the <command>console</command> initscript will do nothing.</para>
|
---|
20 |
|
---|
21 | <para>The <command>console</command> script uses the
|
---|
22 | <filename>/etc/sysconfig/console</filename>
|
---|
23 | as a configuration file. You need to decide which keymap and screen font you
|
---|
24 | will use. The language-specific HOWTO can help you.
|
---|
25 | A pre-made
|
---|
26 | <filename>/etc/sysconfig/console</filename> file with known
|
---|
27 | good settings for several countries was installed with the LFS-Bootscripts
|
---|
28 | package, and you just have to uncomment
|
---|
29 | the relevant section if your country is supported (but read the rest
|
---|
30 | of this section anyway).
|
---|
31 | If still in doubt,
|
---|
32 | look into <filename class="directory">/usr/share/kbd</filename>
|
---|
33 | for valid keymaps and screen fonts. Then read the <command>loadkeys</command>
|
---|
34 | and <command>setfont</command> manual pages and figure out the correct
|
---|
35 | arguments for these programs.
|
---|
36 | Once you decided, create the
|
---|
37 | configuration file with the following command:</para>
|
---|
38 |
|
---|
39 | <screen><userinput>cat >/etc/sysconfig/console <<"EOF"</userinput>
|
---|
40 | KEYMAP="<emphasis>arguments for loadkeys</emphasis>"
|
---|
41 | FONT="<emphasis>arguments for setfont</emphasis>"
|
---|
42 | <userinput>EOF</userinput></screen>
|
---|
43 |
|
---|
44 | <para>E.g., for Spanish users who also want to use the Euro character
|
---|
45 | (accessible by pressing Alt+E),
|
---|
46 | the following settings are correct:</para>
|
---|
47 |
|
---|
48 | <screen><userinput>cat >/etc/sysconfig/console <<"EOF"</userinput>
|
---|
49 | KEYMAP="es euro"
|
---|
50 | FONT="lat9-16 -u iso01"
|
---|
51 | <userinput>EOF</userinput></screen>
|
---|
52 |
|
---|
53 | <para>If the KEYMAP or FONT variable is not set, the console initscript
|
---|
54 | will not run the corresponding program.</para>
|
---|
55 |
|
---|
56 | <para>In some keymaps, the Backspace and Delete keys send characters
|
---|
57 | different form ones in the default keymap built into the kernel.
|
---|
58 | This confuses some applications, e.g. <application>Emacs</application>
|
---|
59 | displays its help (instead of erasing the character before the cursor)
|
---|
60 | when you press Backspace. To check if your keymap is affected (this works
|
---|
61 | only for i386 keymaps):</para>
|
---|
62 |
|
---|
63 | <screen><userinput>zgrep '\W14\W' /path/to/your/keymap</userinput></screen>
|
---|
64 |
|
---|
65 | <para>If you see that keycode 14 is Backspace and not Delete,
|
---|
66 | create the following keymap snippet to fix this issue:</para>
|
---|
67 |
|
---|
68 | <screen><userinput>mkdir -p /etc/kbd & & cat >/etc/kbd/bs-sends-del <<"EOF"</userinput>
|
---|
69 | keycode 14 = Delete Delete Delete Delete
|
---|
70 | alt keycode 14 = Meta_Delete
|
---|
71 | altgr alt keycode 14 = Meta_Delete
|
---|
72 | keycode 111 = Remove
|
---|
73 | altgr control keycode 111 = Boot
|
---|
74 | control alt keycode 111 = Boot
|
---|
75 | altgr control alt keycode 111 = Boot
|
---|
76 | <userinput>EOF</userinput></screen>
|
---|
77 |
|
---|
78 | <para>Then tell the <command>console</command> script to load this snippet
|
---|
79 | after the main keymap:</para>
|
---|
80 |
|
---|
81 | <screen><userinput>cat >>/etc/sysconfig/console <<EOF</userinput>
|
---|
82 | KEYMAP_CORRECTION="/etc/kbd/bs-sends-del"
|
---|
83 | <userinput>EOF</userinput></screen>
|
---|
84 |
|
---|
85 | <para>If back in <xref linkend="chapter-building-system"/> you decided to go
|
---|
86 | compile your keymap directly into the kernel (later on in <xref
|
---|
87 | linkend="chapter-bootable"/>), then strictly speaking you don't need to run the
|
---|
88 | loadkeys program, since the kernel will set up the keymap for you,
|
---|
89 | and thus you may omit the KEYMAP variable from the
|
---|
90 | <filename>/etc/sysconfig/console</filename>
|
---|
91 | configuration file. If you wish,
|
---|
92 | you can still have it, this isn't going to hurt you. Keeping it could even
|
---|
93 | be beneficial, in case you run a lot of different kernels and can't be sure
|
---|
94 | that the keymap is compiled into every one of them.</para>
