I am sponsoring this case for myself and have set the timeout for a week
from today, next Friday, November 6. The case is submitted to PSARC and
cc'ed to LSARC since this updates PSARC 2007/545 for Xvnc and LSARC 2007/625
for vncviewer. The release binding is set to patch as there are no
incompatible changes, but there are no plans for patch/update delivery at
this time.

4. Technical Description
This project replaces the VNC implementation used for Xvnc & vncviewer,
moving from the RealVNC open source release provided by RealVNC, Inc. to
the TigerVNC community-maintained fork. RealVNC has quietly cut back on
new open source releases of their software, with just two minor security
fixes released since 2005. The TigerVNC community project was formed by
the maintainers of several open source distros, who had to independently
maintain the changes needed to make RealVNC work with current Xorg releases
(RealVNC's source releases still only support XFree86 4.x), and developers
from the TightVNC and TurboVNC variants, which provided enhancements over the
original RealVNC sources.
TigerVNC maintains compatibility with the core Remote Frame Buffer (RFB)
protocol used by all VNC implementations, while supporting several
extensions that RealVNC has not adopted, for better compression & security.
The specification of the protocol, with these extensions, is provided in
the case materials as rfbproto.html.
Several command line options have been added to the commands, including
both new functionality, and variants of the existing "colour" options
with the "u" removed for American spelling habits. No incompatible changes
are made. The case materials include diffs of the man pages for reference.
This project also provides a new command, x0vncserver, which connects to a
running X server and exports its display over the RFB protocol to VNC clients.
The vncserver command is modified by this project to start a GNOME session
by default, instead of a simple twm & xterm session. Users with existing
$HOME/.vnc/xstartup scripts will not be affected by this change. The GNOME
session will be started by running /etc/gdm/Xsession if it is found,
otherwise, falling back to running /usr/dt/config/Xsession.jds.
If neither of those are not found, then the default startup will fallback to
the twm & xterm session.
