Unfortunately, on my machine Xwayland immediately crashes when I try to
start it. gdb backtrace:

This appears to be the result of xwl_cursor_confined_to() and
xwl_screen_get_default_seat(). While not against protocol, mutter ends
up sending xdg_output before wl_seat. xwl_screen_get_default_seat()
makes the naïve assumption that we always have a valid seat, we end up
returning a pointer to the empty list itself instead of an actual seat
and causing ourselves to segfault.
So, actually return NULL in xwl_screen_get_default_seat() if the seat
list is empty, and skip any pointer confinement processing in
xwl_cursor_confined_to() when we don't have a seat setup yet.

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.
For a comprehensive overview of X Server and X Window System, consult the
following article:
