Xwayland may open a fair amount of file descriptors for passing Wayland buffers, even more so when using the `wl_shm` either for the pointer cursors or for when GLAMOR is not usable. As a result, Xwayland may hit the (soft) limit of file descriptors leading to a Wayland protocol error and the termination of Xwayland. To mitigate that risk, raise the limit to the maximum (hard) limit of file descriptors (unless of course the limit was set explicitly from the command line with "-lf"). Note that for completeness, the Wayland compositor may have to do the same, otherwise the limit might get reached on the compositor side as well.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
