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
Install GDM by running the following commands:
mkdir build &&
cd build &&
meson setup .. \
--prefix=/usr \
--buildtype=release \
-Dgdm-xsession=true \
-Drun-dir=/run/gdm &&
ninja
This package does not come with a usable test suite.
Now, as the root user:
ninja install
--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.
