132 <para>
133 The <application>gdm</application> login screen is managed by
134 <application>gnome-shell</application>, which relies on the
135 <command>systemd-localed</command> daemon to get the system
136 settings. Since this daemon is not present on this system, a
137 <command>sed</command> is applied in the <xref
138 linkend="gnome-shell"/> instructions to change this behavior,
139 but then <application>gdm</application> uses the system settings,
140 which default to a US <quote>qwerty</quote> keyboard layout. This may
141 be an inconvience to enter a password when the machine keyboard
142 has a different layout. One possibility is to use the screen-keyboard
143 from the accessibility menu. Another possibility is to change the
144 defaults at compile time, by creating the following file:
145 </para>
146
147<screen><userinput>cat &gt; data/dconf/defaults/01-keyboard &lt;&lt; EOF
148<literal>[org/gnome/desktop/input-sources]
149sources=[('xkb','<replaceable>layout</replaceable>')]</literal>
150EOF</userinput></screen>
151
152 <para>
153 where <replaceable>layout</replaceable> should be replaced with
154 the acronym for your keyboard layout (one of the filenames in
155 <filename class="directory">/usr/share/X11/xkb/symbols</filename>).
