GDM-43.0

Installation of 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         \
      -Drun-dir=/run/gdm          \
      -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}
