Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=69388 Commitc100211034
(dix: only show the cursor if a window defines one (#58398)) broke the default cursor behaviour in Xephyr (unless run with -retro). Restore the default cursor visibility so that '-retro' or '-host-cursor' are not needed to have a visible cursor. Signed-off-by: Michele Baldessari <michele@acksyn.org> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> as ofba387cf21f
"ephyr: Use host (HW) cursors by default." this only applies if -sw-cursor is given on the cmdline. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
