VNC redir. -rawfb nullbig, randbig, solid, swirl, etc.
FD_XDM mode to find_display. -listdpy. Add enlightenment.

* x11vnc: Add -autoport and -finddpy utils. -xdummy creation.
tweak xkb tiebreaking again. Shut off -ncache in dev mode.
watch for xrandr events even if no -xrandr. Tips for types
of URLs for java viewers. Add check_redir_services() to
create_display and tsdo() redir helper utility (-tsd).
Improvements to Xdummy.

can also supply host:port to redirect to a different

If 0 <= port < 200 it is taken as a VNC display (5900 is
added to get the actual port), if port < 0 then \fB-port\fR
is used.
.IP
Probably the only reason to use the \fB-redirect\fR option is
in conjunction with SSL support, e.g. \fB-ssl,\fR \fB-ssl\fR SAVE.
This provides an easy way to add SSL encryption to a VNC
server that does not support SSL (e.g. Xvnc or vnc.so)
In fact, the protocol does not even need to be VNC,

If you set the env. var WAITBG=1 x11vnc will go into
the background once listening in wait mode.

Another special mode is FINDCREATEDISPLAY-Xvnc.redirect,
(or FINDDISPLAY-Xvnc.redirect). In this case it will
start up Xvnc as above if needed, but instead of
polling it in its normal way, it simply does a socket
redirection of the connected VNC viewer to the Xvnc.
.IP
So in Xvnc.redirect x11vnc does no VNC but merely
transfers the data back and forth. This should be
faster then x11vnc's polling method, but not as fast
as connecting directly to the Xvnc with the VNC Viewer.
The idea here is to take advantage of x11vnc's display
finding/creating scheme, SSL, and perhaps a few others.
Most of x11vnc's options do not apply in this mode.
.IP
Xvnc.redirect should also work for the vnc.so X server
module for the h/w display however it will work only
for finding the display and the user must already be
logged into the X console.
