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>
