Subject: [PATCH] x0vncserver: add new keysym in case we don't find a matching
keycode
We might often fail to find a matching X11 keycode when the client has
a different keyboard layout and end up with no key event. To avoid a
failure we add it as a new keysym/keycode pair so the next time a keysym
from the client that is unknown to the server is send, we will find a
match and proceed with key event. This is same behavior used in Xvnc or
x11vnc, although Xvnc has more advanced mapping from keysym to keycode.

From f783d5c8b567199178b6690f347e060a69d2aa36 Mon Sep 17 00:00:00 2001

Date: Thu, 11 Aug 2022 13:15:29 +0200
Subject: [PATCH] x0vncserver: update/display cursor only on correct screen in
zaphod mode
We have to check whether we update cursor position/shape only in case
the cursor is on our display, otherwise in zaphod mode, ie. when having
two instances of x0vncserver on screens :0.0 and :0.1 we would be having
the cursor duplicated and actually not funcional (aka ghost cursor) as
it would be actually not present. We also additionally watch EnterNotify
and LeaveNotify events in order to show/hide cursor accordingly.
Change made with help from Olivier Fourdan <ofourdan@redhat.com>
