Cinnamon

Cinnamon is a traditional and modern desktop environment: traditional desktop metaphor as Gnome 2, LXDE or Xfce, with very good graphical and functional features. It is forked from Gnome Shell and developed for Linux Mint. It is provided for Gentoo as a Gnome package: gnome-extra/cinnamon.

Without Systemd
Cinnamon works great without systemd. For that, eselect a profile without Gnome, as this one: default/linux/amd64/13.0/desktop (platform and version can be different). To get system profiles list:

Then to set the system profile:

(where n is profile number).

Also, follow the Gentoo Without Systemd wiki page instructions.

With Systemd
For Cinnamon with systemd, eselect either the default/linux/amd64/13.0/desktop/gnome/systemd profile for system-wide systemd, or default/linux/amd64/13.0/desktop/gnome for Gnome systemd dependencies. The platform and version can be different.

Installing
Of course, Xorg must be first installed for Cinnamon to work.

Cinnamon needs some USEflags:  and. Add them to the system's file:

You also can set them just for Cinnamon install, see below.

Polkit Rules and Actions
For an ordinary user to perform root only actions, put a javascript file in, for example named ( already exists).

Get the list of actions with pkaction, their names are quite self-explanatory:

To authorize an user belonging to  group to suspend, hibernate, shutdown and restart from Cinnamon:

All needed actions can be added to change color profiles, use nano (Cinnamon files manager) as root, mount and eject medias, set screen backlight, use network manager, change wallpaper etc. Just don't make javascript mistakes…! Several  blocks can be used.

Another simpler way is to authorize all actions by only testing  group membership:
