The LXDM is a lightweight Display Manager for the LXDE desktop. It can also be used as an alternative to other Display Managers such as GNOME's GDM or LightDM.
This package is known to build and work properly using an LFS 11.3 platform.
![[Note]](../images/note.png)
The lxdm display manager does not support wayland based window managers such as plasma-wayland or gnome-wayland.

Install LXDM by running the following commands:
./configure --prefix=/usr \
--sysconfdir=/etc \
--with-pam \
--with-systemdsystemunitdir=no &&
make
This package does not come with a test suite.
Now, as the root user:
make install
cat > pam/lxdm << "EOF"
...: Replace default /etc/pam.d/lxdm by another one appropriate for
BLFS.
sed -i ...
data/lxdm.conf.in: Modifications in the default
configuration: (1) fix the background to the default one; (2)
restart X when session is close; (3) typo; and (4) include
XORG_PREFIX, which may be different from
/usr.
sed -i ...
data/Xsession: Source /etc/profile, instead of other file, according to
BLFS standard.
sed -i ... data/lxdm.in: Fix greeter's locale for BLFS specification.
--with-pam: This parameter
enables use of pam authentication.
--with-systemdsystemunitdir=no: BLFS
does not support systemd.
To start lxdm
automatically when the system is switched to runlevel 5, install
the /etc/rc.d/init.d/xdm script and
the /etc/sysconfig/xdm
configuration file included in the blfs-bootscripts-20230101 package and
adjust /etc/inittab by running as
the root user:
make install-lxdm
The LXDM daemon configuration file (/etc/lxdm/lxdm.conf) 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 startlxde with your session of
choice. For GNOME
session=/usr/bin/gnome-session. For OPENBOX session=/usr/bin/openbox-session and
for XFCE
session=/usr/bin/startxfce4.
It is also possible to set the preferred session on a per-user basis by editing the ~/.dmrc file for each user and adding:
[Desktop]
Session=xfce
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
.face.
The lxdm greeter
can be started from the command line as the root user:
telinit 5
Alternatively the runlevel can be permanently set to 5, starting
the lxdm greeter
screen automatically, by modifying /etc/inittab. As the root user:
cp -v /etc/inittab{,-orig} &&
sed -i '/initdefault/ s/3/5/' /etc/inittab
One important script, executed after login is /etc/lxdm/Xsession which we have fixed to fit
BLFS specifications.
