GDM is a system service that is responsible for providing graphical logins and managing local and remote displays.
This package is known to build and work properly using an LFS-9.0 platform.

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/gdm
It is recommended to have a dedicated user and group to take
control of the gdm
daemon after it is started. Issue the following commands as the
root user:
groupadd -g 21 gdm &&
useradd -c "GDM Daemon Owner" -d /var/lib/gdm -u 21 \
-g gdm -s /bin/false gdm &&
passwd -ql gdm
![[Note]](../images/note.png)
The gdm login screen is managed by gnome-shell, which relies on the systemd-localed daemon to get the system settings. Since this daemon is not present on this system, a sed is applied in the gnome-shell-3.32.2 instructions to change this behavior, but then gdm uses the system settings, which default to a US “qwerty” keyboard layout. This may be an inconvience to enter a password when the machine keyboard has a different layout. One possibility is to use the screen-keyboard from the accessibility menu. Another possibility is to change the defaults at compile time, by creating the following file:
cat > data/dconf/defaults/01-keyboard << EOF
[org/gnome/desktop/input-sources]
sources=[('xkb','layout')]
EOF
where layout should be
replaced with the acronym for your keyboard layout (one of the
filenames in /usr/share/X11/xkb/symbols).
Install GDM by running the following commands:
sed 's@systemd@elogind@' -i data/pam-lfs/gdm-launch-environment.pam &&
./configure --prefix=/usr \
--sysconfdir=/etc \
--localstatedir=/var \
--without-plymouth \
--disable-static \
--enable-gdm-xsession \
--with-systemdsystemunitdir=no \
--with-pam-mod-dir=/lib/security &&
make
This package does not come with a usable test suite.
Now, as the root user:
make install
--disable-static: This
switch prevents installation of static versions of the libraries.
--with-initial-vt=7: Use this switch to
make GDM start on VT7 instead of
the first free VT.
--without-plymouth: GDM now
explicitly requires plymouth to be installed. Use this switch to
disable this dependency.
--with-default-pam-config=lfs: Use this
switch if you did not create the /etc/lfs-release file or distribution auto
detection will fail and you will be unable to use GDM.
--enable-gdm-xsession: This
enables the installation of the GDM Xsession file.
The GDM daemon is configured using the /etc/gdm/custom.conf file. Default values are
stored in GSettings in the gdm.schemas file. It is recommended that
end-users modify the /etc/gdm/custom.conf file because the schemas
file may be overwritten when the user updates their system to
have a newer version of GDM.
To start the gdm
automatically when the system is booted, install the /etc/rc.d/init.d/gdm init script included in
the blfs-bootscripts-20190609 package
and set the default runlevel to 5 (graphical login) as the
root user:
make install-gdm
In order to permanently set the default runlevel to 5, starting
the gdm greeter
screen automatically, you can modify /etc/inittab. As the root user:
sed /initdefault/s/3/5/ -i /etc/inittab
You should also disable default elogind power management:
cat >> /etc/elogind/logind.conf << "EOF"
AllowSuspend=no
AllowHibernation=no
EOF
