216 | This command generates an <emphasis>example</emphasis> config file,

217 | which depends on several conditions of the system where it is
|

218 | generated. A few options are <emphasis>defaults</emphasis> from
|
---|
219 | upstream. If there is a previously installed
|
---|
220 | <filename>/etc/sddm.conf</filename>, it will generate a replica. When
|
---|
221 | it is generated during an X session, some session configurations are
|
---|
222 | replicated, e.g. if the cursor from the Adwaita theme is already
|
---|
223 | configured, you will obtain <emphasis>CursorTheme=Adwaita</emphasis>

451 | <para>
|

452 | In the next couple of paragraphs, due to a problem with sddm-greeter,
|
---|
453 | we mention how to define the keyboard used there. Notice that this is
|
---|
454 | also the keyboard that will be used in the X session, unless there is
|
---|
455 | a configuration in the Desktop Environment or in the Window Manager
|
---|
456 | overriding it, afterwards.

460 | <para>
|
---|
461 | Keyboard selection: the greeter shows a double question mark or the
|
---|
462 | wrong keyboard. When you start to type the password or user name
|
---|
463 | (depending on the theme, only password), the right keyboard selection
|
---|
464 | magically appears. Optionally, a workaround is to include the keyboard
|
---|
465 | list in <command>/usr/share/sddm/scripts/Xsetup</command> script, as the
|
---|
466 | <systemitem class="username">root</systemitem> user:
|
---|
467 | </para>
|
---|
468 |
|
---|
469 | <screen role="root"><userinput>echo 'setxkbmap <replaceable>"<your keyboard comma separated list>"</replaceable>' >> \
|
---|
470 | /usr/share/sddm/scripts/Xsetup</userinput></screen>
|
---|
471 |
|
---|
472 | <para>
|
---|
473 | E.g. <command>echo 'setxkbmap "fr,gb,br,us"' >>
|
---|
474 | /usr/share/sddm/scripts/Xsetup</command>. A very accurate definition
|
---|
475 | of the keyboard(s) is possible, for example: <command>echo 'setxkbmap
|
---|
476 | -model pc105 -layout br,us -variant abnt2,dvorak -keycodes evdev'
|
---|
477 | >> /usr/share/sddm/scripts/Xsetup</command>. See man setxkbmap.
