Installation of LXDM

First, some fixes.

cat > pam/lxdm << "EOF" &&
#%PAM-1.0
auth        required    pam_unix.so
auth        requisite   pam_nologin.so
account     required    pam_unix.so
password    required    pam_unix.so
session     required    pam_unix.so
EOF

sed -i 's:sysconfig/i18n:profile.d/i18n.sh:g' data/lxdm.in &&
sed -i 's:/etc/xprofile:/etc/profile:g' data/Xsession &&
sed -e 's/^bg/#&/'        \
    -e '/reset=1/ s/# //' \
    -e 's/logou$/logout/' \
    -e "/arg=/a arg=$XORG_PREFIX/bin/X" \
    -i data/lxdm.conf.in

Install LXDM by running the following commands:

./configure --prefix=/usr     \
            --sysconfdir=/etc \
            --with-pam        &&
make

This package does not come with a test suite.

Now, as the root user:

make install

Command Explanations

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.

Configuring LXDM

Config Files

/etc/lxdm/lxdm.conf

Boot Script

Install the /etc/rc.d/init.d/lxdm init script from the blfs-systemd-units-20160602 package.

make install-lxdm

Configuration Information

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.
