 I downloaded and installed **RaspiOS 2020-05-27 Buster**, based on Debian 10. I choosed the **full** version "with desktop and recommended software".
-FIXME The WiFi is handled by Network Manager? The **/etc/wpa_supplicant/wpa_supplicant.conf** does conflict with Network Manager? The **/boot/wpa_supplicant.conf** trick explained in [[https://www.raspberrypi.org/documentation/configuration/wireless/headless.md|Setting up a Raspberry Pi headless]] does conflict as well?
+==== WiFi ====
+I installed the **Xfce** desktop environment; on Debian 10 this is bundled with the **[[https://packages.debian.org/buster/network-manager|NetworkManager]]** service, which handles wired and wireless connections.
+Beware that NetworkManager does conflict with the **/etc/wpa_supplicant/wpa_supplicant.conf** configuration file: if you configure a WiFi connection in this file, you will end-up with two **wpa_supplicant** instances conflicting each other (so you shouldn't even use the trick to [[https://www.raspberrypi.org/documentation/configuration/wireless/headless.md|setup a Raspberry Pi headless]]). Use instead the NetworkManager applet from the Xfce environment to connect to your WiFi network, the network preferences will be saved into **/etc/NetworkManager/system-connections/**.

 ==== Hide the mouse pointer ====
-If you use only the keyboard to control the interface, the **mouse pointer** at the center of the screen is definitely annoying. Fortunately enough there is the Debian package **unclutter**: once installed you will find a running process when you initiate your desktop session:
+The **[[https://github.com/RigacciOrg/photo-reframe-slideshow|photo-reframe]]** program used as directory browser and slideshow, uses the **setOverrideCursor()** function to **hide the mouse pointer** when run full screen.

 The mouse pointer will disappear after one second of **idle time**, just to reappear if you move the mouse. If you want to customize the options, change the file **/etc/default/unclutter**.
+:!: Unfortunately the **unclutter** program **does not work in Wayland**, which is the graphical backend installed by the Raspberry Pi OS based on Debian 12, in replacement of the legacy X11. If you search for an hide cursor solution on Wayland, beware of this [[https://github.com/seffs/wayfire-plugins-extra-raspbian/releases|hide-cursor plugin]] which is intended for the **Wayland** + **Wayfire** environment (backend and window manager). On the Raspberry Pi 2 only the **Wayland** + **Labwc** environment is supported. For this reason I decided to use raspi-congif and [[raspberry_x_wayland|revert back to the X11]].

 See the man page for **nm-system-settings.conf**, the article **[[https://fedoramagazine.org/randomize-mac-address-nm/|Randomize your MAC address using NetworkManager]]** and this **[[https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=196348&start=25#p1524581|post]]** on how to disable it on the Raspberry Pi.
+Alternatively you can uninstall the **NetworkManager** package and use **dhcpcd5** for all the network settings.
