Hi,

Not currently, but only because nobody has bothered to try yet, so
patches welcome. We don't need any configure option for this; instead,
the configure script should simply detect whether GTK+ was built with
X11 support, by using PKG_CHECK_VAR to look at the "target" GTK+ pkg-
config variable. (Checking mine in /usr/lib64/pkgconfig/gtk+-3.0.pc I
see the value of mine is "x11 broadway wayland". If x11 were not listed
there, then we would want to drop the x11 and libwnck pkg-config checks
from the configure script.

Then, you'll need to hunt down X11-specific code, for example this code
in ephy-shell.c:

  if (GDK_IS_X11_DISPLAY (gdk_display_get_default ()))
    wnck_screen_force_update (wnck_screen_get_default ());

And add preprocessor guards:

#ifdef GDK_WINDOWING_X11
  if (GDK_IS_X11_DISPLAY (gdk_display_get_default ()))
    wnck_screen_f
orce_update (wnck_screen_get_default ());
#endif

Should be easy, but all of our current distributors still need the X11
support, so it hasn't been a priority for us.
