+Start a new X11 server using Xephyr and attach the sandbox to this server.
+Xephyr is a display server implementing the X11 display server protocol.
+It runs in a window just like other X applications, but it is an X server itself in which you can run other software.
+The default Xephyr window size is 800x600. This can be modified in /etc/firejail/firejail.config file,
+see \fBman 5 firejail-config\fR for more details.

+The recommended way to use this feature is to run a window manager inside the sandbox.
+A security profile for OpenBox is provided.
