* x11vnc: add -xrefresh option, fix KDE .DCOPserver parse bug,
make sure UNIXPW_DISABLE_LOCALHOST/-unixpw_unsafe ignore
any SSH tunnel that would imply -localhost.

You can, but you would not be doing this for performance reasons (for
virtual X sessions via VNC, Xvnc should give the fastest response).
You may want to do this because Xvnc does not support an X server
extension you desire, or you want to take advantage of one of x11vnc's
unending number of options and features.
You may want to do this because Xvnc is buggy and crashes, does not
support an X server extension you desire, or you want to take
advantage of one of x11vnc's unending number of options and features.
One way to acheive this is to have a Xvfb(1) virtual framebuffer X
server running in the background and have x11vnc attached to it.
Another method, faster and more accurate is to use the "dummy" Device
Driver in XFree86/Xorg (see below). One could view this desktop both
remotely and also [567]locally using vncviewer. Make sure vncviewer's
"-encodings raw" is in effect for local viewing (compression seems to
slow things down locally). For local viewing you set up a "bare"
window manager that just starts up vncviewer and nothing else
([568]See below).

In either case, one can view this desktop both remotely and also

is in effect for local viewing (compression seems to slow things down

just starts up vncviewer and nothing else ([568]See how below).
Here is one way to start up Xvfb:
xinit -- /usr/X11R6/bin/Xvfb :1 -cc 4 -screen 0 1024x768x16
This starts up a 16bpp virtual display. To export it via VNC use
"x11vnc -display :1 ...". The "-cc 4" option is to force Xvfb to use a
TrueColor visual instead of DirectColor.
x11vnc -display :1 ...
Then have the remote vncviewer attach to x11vnc's VNC display (e.g. :0
which is port 5900).
The "-cc 4" Xvfb option is to force it to use a TrueColor visual
instead of DirectColor (this works around a recent bug in the Xorg
Xvfb server).
One good thing about Xvfb is that the virtual framebuffer exists in
main memory (rather than in the video hardware), and so x11vnc can
"screen scrape" it efficiently (more than, say, 100X faster than
"screen scrape" it very efficiently (more than, say, 100X faster than
normal video hardware).

There are some annoyances WRT Xvfb however. The default keyboard
mapping seems to be very poor. One should run x11vnc with

A user points out a faster and more accurate method is to use the
