 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.
+The default is **Wayland** + **Labwc** for all the Raspberry Pi models, including the Pi 2.
 Start the **raspi-config** and navigate the **Advanced Options** => **Wayland** to make your choice.

-===== Wayland not starting =====
+===== Wayland Wayfire not starting on the Raspberry Pi 2 =====
+On the Raspberry Pi 2 the Wayland Wayfire does not start. Fortunately enough the ''raspi-config'' added into the **/etc/lightdm/lightdm.conf** configuration file the **fallback-session** option, which launches the legacy X11.
+I discovered it because I installed the **hide-cursor** Wayfire plugin, but the plugin did not work. Actually the entire Wayfire was not running!
+As per **Raspbian GNU/Linux 12 (bookworm)**, [[https://www.howtogeek.com/raspberry-pi-os-wayland-rollout/|Raspberry Pi OS Switches to Wayland on All Pi Models]], and [[https://hackaday.com/2024/10/28/raspberry-pi-oss-wayland-transition-completed-with-switch-to-labwc/|Raspberry Pi OS’s Wayland Transition Completed With Switch To Labwc]].
+Wayfire is more resource-intensive than Labwc, so its use is discouraged and it will no start on the **Raspberry Pi 2**. Infact the **/usr/bin/xfallback.sh** script will return zero if run on the Pi 2.
