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-9.1 platform.

First, some fixes.

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.
Install the /etc/rc.d/init.d/lxdm
init script from the blfs-bootscripts-20191204 package.
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.
You can manually start lxdm, e.g, if the bootscript
has been installed, by running, as root user:
/etc/rc.d/init.d/lxdm start
By convention, X should be executed at runlevel 5, consequently,
the same is true for lxdm.
However, the LFS default runlevel is 3. Changing to runlevel 5,
from the console (as root user)
starts the lxdm
bootscript and presents the greeter screen:
init 5
In order to permanently set the default to 5, starting the
lxdm greeter screen
automatically, you can modify /etc/inittab. As the root user:
cp -v /etc/inittab{,-orig} &&
sed -i '/initdefault/ s/3/5/' /etc/inittab
You should also disable default elogind power management:
cat >> /etc/elogind/logind.conf << "EOF"
AllowSuspend=no
AllowHibernation=no
EOF

One important script, executed after login is /etc/lxdm/Xsession which we have fixed to fit
BLFS specifications.
