OpenRC changes

Warning

Some features used may depend on experimental upstream OpenRC features. As I write this, this isn't the case but it may change.

This is a patch-over of GNOME-session for OpenRC users. It creates a new leader, ctl tool, as well as some init scripts to make GNOME session work.

This was created for Gentoo, as we plan to use this but only apply a patch over the core gnome-session meson files and just drop the new files in. This is because USE=systemd implementation should work just fine without any adjustments (and it makes bumping a little easier).

For other distributions that use OpenRC, as far as I'm aware, things should also work just fine. YMMV :-)

Applying the changes

First, apply the changes:

$ git clone https://gitlab.gnome.org/GNOME/gnome-session.git
$ rsync -av gnome-session-openrc/ /path/to/gnome-session

Now create the gdm-greeter user (unless you build with userdb support, which you probably haven't yet as I write this):

$ # This has to be /var/lib/gdm-greeter until 
$ useradd -rm -d /var/lib/gdm-greeter -G gdm gdm-greeter

You may add gdm-greeter{-2,-3,-4} as well but this is an edge case for multiseat greeters. Best to wait until userdb support (properly) lands into elogind.

Note

The /var/lib/gdm-greeter user must be done until GNOME/gdm#325 gets merged

For each user you want to login as, add the dbus user service to the boot runlevel (this blocks pam_openrc.so from finishing before dbus is ready, and on some devices may cause gnome-session to not start):

$ rc-update -U add dbus boot

Assuming you already installed GNOME 49 and GDM 49 (you can snag the ones from my repo for now), then you can build the new gnome-session:

$ cd /path/to/gnome-session # Not this repo! The one we applied into!
$ meson setup build --prefix /usr
$ cd build && sudo ninja install

And of course, update your PAMs if you haven't:

0. Append -session optional pam_openrc.so to /etc/pam.d/gdm-launch-environment.
1. Add -session optional pam_openrc.so before session include system-local-login (this is a weird workaround, haven't figured it out yet).

Happy GNOMEing!
