[b32e803] | 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>
|
---|
[1050066] | 20 |
|
---|
[b32e803] | 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 | In the future releases of LFS-Bootscripts, there will be a pre-made
|
---|
| 26 | <filename>/etc/sysconfig/console</filename> file with known
|
---|
| 27 | good settings for several countries, and you will just have to uncomment
|
---|
| 28 | the relevant section.
|
---|
| 29 | If still in doubt,
|
---|
| 30 | look into <filename class="directory">/usr/share/kbd</filename>
|
---|
| 31 | for valid keymaps and screen fonts. Then read the <command>loadkeys</command>
|
---|
| 32 | and <command>setfont</command> manual pages and figure out the correct
|
---|
| 33 | arguments for these programs.
|
---|
| 34 | Once you decided, create the
|
---|
| 35 | configuration file with the following command:</para>
|
---|
| 36 |
|
---|
| 37 | <screen><userinput>cat >/etc/sysconfig/console <<"EOF"</userinput>
|
---|
| 38 | KEYMAP="<emphasis>arguments for loadkeys</emphasis>"
|
---|
| 39 | FONT="<emphasis>arguments for setfont</emphasis>"
|
---|
| 40 | <userinput>EOF</userinput></screen>

| 41 |
|
---|
| 42 | <para>E.g., for Spanish users who also want to use the Euro character
|
---|
| 43 | (accessible by pressing Alt+E),
|
---|
| 44 | the following settings are correct:</para>
|
---|
| 45 |
|
---|
| 46 | <screen><userinput>cat >/etc/sysconfig/console <<"EOF"</userinput>
|
---|
| 47 | KEYMAP="es euro"
|
---|
| 48 | FONT="lat9-16 -u iso01"
|
---|
| 49 | <userinput>EOF</userinput></screen>
|
---|
| 50 |
|
---|
| 51 | <para>If the KEYMAP or FONT variable is not set, the console initscript
|
---|
| 52 | will not run the corresponding program.</para>
|
---|
| 53 |
|
---|
| 54 | <para>In some keymaps, the Backspace and Delete keys send characters
|
---|
| 55 | different form ones in the default keymap built into the kernel.
|
---|
| 56 | This confuses some applications, e.g. <application>Emacs</application>
|
---|
| 57 | displays its help (instead of erasing the character before the cursor)
|
---|
| 58 | when you press Backspace. To check if your keymap is affected (this works
|
---|
| 59 | only for i386 keymaps):</para>

[b32e803] | 62 |
|

| 63 | <para>If you see that keycode 14 is Backspace and not Delete,

|

| 66 | <screen><userinput>mkdir -p /etc/kbd & & cat >/etc/kbd/bs-sends-del <<"EOF"</userinput>

|
---|
| 74 | <userinput>EOF</userinput></screen>
|
---|
| 75 |
|
---|
| 76 | <para>Then tell the <command>console</command> script to load this snippet
|
---|
| 77 | after the main keymap:</para>
|
---|
| 78 |
|
---|
| 79 | <screen><userinput>cat >>/etc/sysconfig/console <<EOF</userinput>

| 80 | KEYMAP_CORRECTION="/etc/kbd/bs-sends-del"

|
---|
| 82 |
|
---|
| 83 | <para>If back in <xref linkend="chapter-building-system"/> you decided to go
|
---|
| 84 | compile your keymap directly into the kernel (later on in <xref
|
---|
| 85 | linkend="chapter-bootable"/>), then strictly speaking you don't need to run the
|
---|
| 86 | loadkeys program, since the kernel will set up the keymap for you,
|
---|
| 87 | and thus you may omit the KEYMAP variable from the
|
---|
| 88 | <filename>/etc/sysconfig/console</filename>
|
---|
| 89 | configuration file. If you wish,
|
---|
| 90 | you can still have it, this isn't going to hurt you. Keeping it could even
|
---|
| 91 | be beneficial, in case you run a lot of different kernels and can't be sure
|
---|
| 92 | that the keymap is compiled into every one of them.</para>
