With the operating system Raspbian GNU/Linux 12 (bookworm) it is possibile to choose between the traditional X11 graphical backend and the new Wayland. With X11 you can use only the Openbox window manager, while in Wayland you can choose Wayfire or the Labwc window manager.

Start the raspi-config and navigate the Advanced Options ⇒ Wayland to make your choice.

If you are using the default LightDM desktop manager, the settings are saved into /etc/lightdm/lightdm.conf. Here are the settings for Wayland Wayfire and Labwc respectively:

greeter-session=pi-greeter-wayfire
user-session=LXDE-pi-wayfire
autologin-session=LXDE-pi-wayfire
fallback-test=/usr/bin/xfallback.sh
fallback-session=LXDE-pi-x
fallback-greeter=pi-greeter

greeter-session=pi-greeter-labwc
user-session=LXDE-pi-labwc
autologin-session=LXDE-pi-labwc
