-Wayland does not specify a native interface for the compositor for taking screenshots and it [[https://gitlab.freedesktop.org/wayland/wayland/-/issues/32|looks like]] it never will.+Originally Wayland wasn't meant to have protocols allowing screenshots ([[https://gitlab.freedesktop.org/wayland/wayland/-/issues/32|see here]]), that is about to change with [[https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/4545|new proposed protocols]]. In the meantime we decided to use wlroots' [[https://gitlab.freedesktop.org/wlroots/wlr-protocols/-/blob/master/unstable/wlr-screencopy-unstable-v1.xml|screencopy protocol]] because that's probably what our compositor will support.
  
-So for xfce4-screenshooter there are the following options: +At the moment only Entire Screen screenshots are supported ([[https://gitlab.xfce.org/apps/xfce4-screenshooter/-/merge_requests/52|xfce4-screenshooter!52]]), Rectangle Selection will be implemented next but Active Window is going to be much trickier, perhaps we'll need a custom protocol for our compositor to take care of that. 
-  * Add support for the wlroots screencopy protocol +

(Though some things might work in some cases)
  
-==== Native Wayland  ==== +A wlroots compositor is almost a prerequisite for most core components (as well as panel plugins and some apps), at least to ensure that all features ported to Wayland are available. The default compositor is labwc, but wayfire is another wlroots compositor on which tests have generally been carried out. 
-  * Install Weston with your distribution package manager (if a Wlroots-based compositor is required, as for **[[#xfce4-panel]]**, see [[https://gitlab.xfce.org/xfce/xfce4-panel/-/merge_requests/103|this MR]] for more information) + 
-  * Maybe set a minimal configuration, for example <file ini ~/.config/weston.ini>[keyboard] +To start an Xfce session on Wayland, you can run ''startxfce4 %%--%%wayland'' from a tty, which will launch xfce4-session from labwc. If you want to use wayfire instead, you'll need to run ''startxfce4 %%--%%wayland wayfire'' and add this configuration first, as wayfire doesn't have a ''%%--%%startup'' option like labwc (see ''startxfce4 %%--%%help'' for details): 
-keymap_layout=fr +<file ini ~/.config/wayfire.ini> 
-numlock-on=true+[autostart] 
 +session = xfce4-session
 </file> </file>
-  * Run ''weston'' in a terminal emulator, or better: in a tty with a different user, or by logging out of the X11 session first (the compositor may not have quite the same behavior, and this avoids interactions with the current environment) + 
-  * If run in a terminal emulator, make sure at least the component to test isn't already running in your X11 session (e.g Thunar as daemon) +Configuration adaptations may be required for other compositors as well, if they also don't have a ''%%--%%startup'' option to pass to startxfce4. 
-  * Open a terminal in the Weston session and start the component which is to be tested+ 
 +A ''@datadir@/wayland-sessions/xfce-wayland.desktop'' file has also been added to xfce4-session for display managers, such as lightdm, with which this has been tested. The command line must also be modified in this file to use a compositor other than the default one.
