User Notes: https://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
First, adapt GDM to build without systemd present:
sed -i -r '/(^| )systemd_dep/d' meson.build
Install GDM by running the following commands:
sed -e 's@systemd@elogind@' \
-e '/elogind/isession required pam_loginuid.so' \
-i data/pam-lfs/gdm-launch-environment.pam &&
mkdir build &&
cd build &&
meson --prefix=/usr \
--buildtype=release \
-Dgdm-xsession=true \
-Dsystemd-journal=false \
-Dsystemdsystemunitdir=/tmp \
-Dsystemduserunitdir=/tmp .. &&
ninja
This package does not come with a usable test suite.
Now, as the root user:
ninja install &&
rm -rv /tmp/*.{service,target.d}
--buildtype=release:
Specify a buildtype suitable for stable releases of the package, as
the default may produce unoptimized binaries.
-Dinitial-vt=7: Use this switch to make
GDM start on VT7 instead of the
first free VT.
-Ddefault-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.
-Dgdm-xsession=true: 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 gdm
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-20210826 package and
adjust /etc/inittab by running 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
