Description Bastien Nocera 2007-08-20 19:06:31 UTC
gtk-vnc-0.1.0-3.fc8 on x86_64
OXSVNC 1.71 on MacOS X 10.4.10 (iirc)

The cursor doesn't show up on the screen, but highlights/tooltips show up where
the cursor should be. Works fine with vncviewer.

Daniel, what changes would this need to vinagre to work?

Comment 2 Daniel Berrangé 2007-08-26 19:32:16 UTC
I've been trying to figure out what's wrong here. The VNC server itself should
always render a cursor. The client (viewer) may or may not render a cursor at
its discretion, or it may negotiate with the server to render the server cursor
locally. GTK-VNC doesn't support local rendering of the server cursor yet, so a
well behaved server should always be rendering the cursor itself. My best guess
at this time is that this is probably a bug in the OSX VNC server - expecting
the client viewer program to always support the local cursor renderering extension.
I think the best option for a quick workaround is to unhide the local cursor
with vnc_display_set_point_local(vnc, TRUE).

I need to to continue investigating just what the real cause is though because
I'd really rather only have a server cursor visible (whether rendering locally
or remotely). Will probably have to just implement the cursor extension to VNC.

Implement rich cursor extension

Can you give this patch a try - it implenents the rich cursor offload extension
which OSX-VNC seems to want.

Patch to add RichCursor + XCursor extensions

This updated patch implements both the richcursor and xcursor extensions which
should be enough for any server.

Comment 5 Daniel Berrangé 2007-09-14 04:40:31 UTC
Release 0.2.0 pushed to rawhide, implementing both RichCursor & XCursor extensions
