The LXDM daemon configuration file
|
|
(<filename>/etc/lxdm/lxdm.conf</filename>) specifies options that
|
|
include numlock on/off, background image (bg), session, etc. You can
|
|
set a default session by uncommenting the line:
|
|
session=/usr/bin/startlxde and replacing <command>startlxde</command>
|
|
with your session of choice. For <application>GNOME</application>
|
|
session=/usr/bin/gnome-session. For <application>OPENBOX</application>
|
|
session=/usr/bin/openbox-session and for
|
|
<application>XFCE</application> session=/usr/bin/startxfce4.
|
|
</para>
|
|
|
|
<para>
|
|
It is also possible to set the preferred session on a per-user basis by
|
|
editing the ~/.dmrc file for each user and adding:
|
|
<screen><literal>[Desktop]
|
|
Session=xfce</literal></screen>
|
|
</para>
|
|
|
|
<para>
|
|
You can replace the default dummy face in the greeting screen by another
|
|
image representing your user. For that, copy or symlink the desired
|
|
image to your home directory with the name <filename>.face</filename>.

<title>Starting lxdm</title>

<para>

You can manually start <command>lxdm</command>, e.g, if the bootscript
|
|
has been installed, by running, as <systemitem
|

By convention, X should be executed at runlevel 5, consequently, the
|
|
same is true for <application>lxdm</application>. However, the LFS default
|
|
runlevel is 3. Changing to runlevel 5, from the console (as
|
|
<systemitem class="username">root</systemitem> user) starts the
|
|
<command>lxdm</command> bootscript and presents the
|
|
greeter screen:

|
|
|

<screen role="root"><userinput>init 5</userinput></screen>
|
|

|
<para>
|
|
In order to permanently set the default to 5, starting the
|
|
<command>lxdm</command> greeter screen automatically, you can modify
|
|
<filename>/etc/inittab</filename>. As the <systemitem
|
|
class="username">root</systemitem> user:

</para>
|
|
|

<para>

One important script, executed after login is

<filename>/etc/lxdm/Xsession</filename> which we have fixed to fit

BLFS specifications.
