GDM-2.6.0.2

Introduction to GDM

The GDM package contains GNOME's Display Manager daemon. This is useful for allowing configurable graphical logins.

Package information

Installation of GDM

Install GDM by running the following commands:

groupadd gdm &&
useradd -c gdm -d /dev/null -g gdm -s /bin/bash gdm &&
./configure --prefix=`pkg-config --variable=prefix ORBit-2.0` \
    --libexecdir=`pkg-config --variable=prefix ORBit-2.0`/sbin \
    --sysconfdir=/etc/gnome --localstatedir=/var/lib \
    --with-pam-prefix=/etc &&
make &&
make install

Command explanations

--sysconfdir=/etc/gnome: This command puts configuration files in /etc/gnome instead of /opt/gnome2/etc.

--localstatedir=/var/lib: This command puts files in /var/lib instead of /opt/gnome2/var.

--with-pam-prefix=/etc: This command puts PAM configuration files in /etc/pam.d instead of /etc/gnome.

Configuring GDM

Config files

gdm.conf

Configuration Information

The GDM PAM config files contain modules not present in a BLFS installation. The following commands will replace those files:

cat > /etc/pam.d/gdm << "EOF"
auth        required    pam_unix.so
auth        required    pam_nologin.so
account     required    pam_unix.so
password    required    pam_unix.so
session     required    pam_unix.so
EOF
cat > /etc/pam.d/gdm-autologin << "EOF"
auth        required    pam_env.so
auth        required    pam_nologin.so
auth        required    pam_permit.so
account     required    pam_unix.so
password    required    pam_unix.so
session     required    pam_unix.so
EOF

gdm can be tested by executing it from a root console.

To start a graphical login at boot, install the /etc/rc.d/init.d/gdm init script included in the blfs-bootscripts-5.1 package.

make install-gdm

To autostart with a graphical login, edit /etc/inittab so that the line containing:

id:3:initdefault:

is changed to:

id:5:initdefault:
