+Subject: [PATCH] meson: allow building with elogind
+
+Currently, the GDM meson build has a hard dependency on systemd.
+However, GDM can function just fine if one is using elogind. This allows
+a user to build GDM against libelogind and also disable the systemd
+system and user units.

+GDM is a system service that is responsible for providing graphical
+logins and managing local and remote display.
+
+Critical note on Slackware:
+Slackware has it's '/etc/rc.d/rc.4' script starting gdm with an invalid
+command line option, which will cause gdm to fail starting in runlevel
+4. To use gdm, you will need to edit '/etc/rc.d/rc.4' to remove the 
+'-nodaemon' option from being passed to gdm. After editing, the gdm 
+lines should look like this:
+
+if [ -x /usr/bin/gdm ]; then
+  exec /usr/bin/gdm
+fi
+
+# Someone thought that gdm looked prettier in /usr/sbin,
+# so look there, too:
+if [ -x /usr/sbin/gdm ]; then
+  exec /usr/sbin/gdm
+fi
+
+A note on PAM:
+The GDM source includes PAM configs for linux distros like redhat, lfs,
+and arch. However, none of these pre-designed configs are suitable for 
+Slackware's PAM configuration. Therefore I used 'sddm' as a reference
+and wrote configs for 'gdm' that work properly. I didn't include 
+'gdm-fingerprint' or 'gdm-smartcard', since I don't have the hardware 
+needed to properly test functionality. 
+
+Additional Notes:
+- Slackware comes with the 'gdm' group and user already configured, so 
+nothing needs to be done there.
+
+- GDM can be built without 'gnome-session' and 'gnome-shell' installed,
+but 'gdm' will be unusable at runtime without them.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
