motion can cause rapid changes on the screen, e.g. a an alias. The problem is pointer motion can cause
window drag. Neither x11vnc's screen polling nor the rapid changes on the screen: consider the rapid changes
when you drag a large window around. Neither x11vnc's
screen polling and vnc compression routines nor the
bandwidth to the vncviewers can keep up these rapid bandwidth to the vncviewers can keep up these rapid
screen changes: everything bogs down when dragging screen changes: everything will bog down when dragging
or scrolling. Note that most video h/w is optimized or scrolling. So a scheme has to be used to "eat"

the video card read rate, and how many tiles have been

The default n is 2. Note that modes 2, 3, 4 will skip
\fB-input_skip\fR keyboard events (but it will not count
pointer events). Also note that these modes are not
available in \fB-threads\fR mode which has its own pointer
event handling mechanism.
.IP
To try out the different pointer modes to see
which one gives the best response for your usage,
it is convenient to use the remote control function,
e.g. "x11vnc \fB-R\fR pointer_mode:4" or the tcl/tk gui
(Tuning -> pointer_mode -> n).

\fB-speeds\fR \fIrd,bw,lat\fR
.IP
x11vnc tries to estimate some speed parameters that
are used to optimize scheduling (e.g. \fB-pointer_mode\fR
4) and other things. Use the \fB-speeds\fR option to set
these manually. The triple \fIrd,bw,lat\fR corresponds
to video h/w read rate in MB/sec, network bandwidth to
clients in KB/sec, and network latency to clients in
milliseconds, respectively. If a value is left blank,
e.g. "\fB-speeds\fR \fI,100,15\fR", then the internal scheme is
used to estimate the empty value(s).
.IP
Typical PC video cards have read rates of 5-10 MB/sec.
If the framebuffer is in main memory instead of video
h/w (e.g. SunRay, shadowfb, Xvfb), the read rate may
be much faster. "x11perf \fB-getimage500"\fR can be used
to get a lower bound (remember to factor in the bytes
per pixel). It is up to you to estimate the network
bandwith to clients. For the latency the
.IR ping (1)
command can be used.

e.g. "\fB-speeds\fR \fImodem\fR". The aliases are: "modem" for

\fB-snapfb\fR
.IP
Instead of polling the X display framebuffer (fb) for
changes, periodically copy all of X display fb into main
memory and examine that copy for changes. Under some
circumstances this will improve interactive response,
or at least make things look smoother, but in others
(many) it will make the response worse. If the video
h/w fb is such that reading small tiles is very slow
this mode could help. To keep the "framerate" up
the screen size x bpp cannot be too large. Note that
this mode is very wasteful of memory I/O resources
(it makes full screen copies even if nothing changes).
It may be of use in video capture-like applications,
or where window tearing is a problem.
