text selection, and some menu traversals. It overrides
any -pointer_mode setting.
-ncache n Client-side caching scheme. Framebuffer memory "n"
(an integer) times that of the full display is allocated
below the actual framebuffer to cache screen contents
for rapid retrieval. So a W x H frambuffer is expanded
to a W x (n+1)*H one. Use 0 to disable. Default: XXX.
For this and the other -ncache* options below you can
abbreviate "-ncache" with "-nc". Also, "-nonc"
is the same as "-ncache 0"
This is an experimental option, currently implemented
in an awkward way in that in the VNC Viewer you can
see the cache contents if you scroll down, etc. So you
will have to set things up so you can't see that region.
If this method is successful, the changes required for
clients to do this less awkwardly will be investigated.
Note that this mode consumes a huge amount of memory,
both on the x11vnc server side and on the VNC Viewer
side. If n=2 then the amount of RAM used is roughly
tripled for both x11vnc and the VNC Viewer. As a rule
of thumb, note that 1280x1024 at depth 24 is about 5MB
of pixel data.
For reasonable response when cycling through 4 to 6
large (e.g. web browser) windows a value n of 6 to 12
is recommended. (that's right: ~10X more memory...)
Because of the way window backingstore and saveunders
are implemented, n must be even. It will be incremented
by 1 if it is not.
This mode also works for native MacOS X, but may not
be as effective as the X version. This is due to a
number of things, one is the drop-shadow compositing
that leaves extra areas that need to be repaired (see
-ncache_pad). Another is the window iconification
animations need to be avoided (see -macicontime).
It appears the that the 'Scale' animation mode gives
better results than the 'Genie' one. Also, window event
detection not as accurate as the X version.
-ncache_cr In -ncache mode, try to do copyrect opaque window
moves/drags instead of wireframes (this can induce
painting errors). The wireframe will still be used when
moving a window whose save-unders has not yet been set
or has been invalidated.
Some VNC Viewers provide better response than others
with this option. On Unix, realvnc viewer gives
smoother drags than tightvnc viewer. Response may also
be choppy if the server side machine is too slow.
Sometimes on very slow modem connections, this actually
gives an improvement because no pixel data at all
(not even the box animation) is sent during the drag.
-ncache_no_moveraise In -ncache mode, do not assume that moving a window
will cause the window manager to raise it to the top
of the stack. The default is to assume it does, and
so at the beginning of any wireframe, etc, window moves
the window will be pushed to top in the VNC viewer.
-ncache_no_dtchange In -ncache mode, do not try to guess when the desktop
(viewport) changes to another one (i.e. another
workarea). The default is to try to guess and when
detected try to make the transistion more smoothly.
-ncache_no_rootpixmap In -ncache mode, do not try to snapshot the desktop
background to use in guessing or reconstructing window
save-unders.
-ncache_keep_anims In -ncache mode, do not try to disable window
manager animations and other effects (that usually
degrade ncache performance or cause painting errors).
The default is to try to disable them on KDE (but not
GNOME) when VNC clients are connected.
For other window managers or desktops that provide
animations, effects, compositing, translucency,
etc. that interfere with the -ncache method you will
have to disable them manually.
-ncache_old_wm In -ncache mode, enable some heuristics for old style
window managers such as fvwm and twm.
-ncache_pad n In -ncache mode, pad each window with n pixels for the
caching rectangles. This can be used to try to improve
the situation with dropshadows or other compositing
(e.g. MacOS X window manager), although it could make
things worse. The default is 0 on Unix and 24 on
MacOS X.
-wireframe [str] Try to detect window moves or resizes when a mouse
-nowireframe button is held down and show a wireframe instead of
the full opaque window. This is based completely on

\fB-ncache_pad).\fR Another is the window iconification
animations need to be avoided (see \fB-macicontime).\fR
It appears the that the 'Scale' animation mode gives
better results than the 'Genie' one. Also, window event
detection not as accurate as the X version.
.PP
\fB-ncache_cr\fR
.IP
In \fB-ncache\fR mode, try to do copyrect opaque window
moves/drags instead of wireframes (this can induce
painting errors). The wireframe will still be used when
moving a window whose save-unders has not yet been set
or has been invalidated.
.IP
Some VNC Viewers provide better response than others
with this option. On Unix, realvnc viewer gives
smoother drags than tightvnc viewer. Response may also
be choppy if the server side machine is too slow.
.IP
Sometimes on very slow modem connections, this actually
gives an improvement because no pixel data at all
(not even the box animation) is sent during the drag.
.PP
\fB-ncache_no_moveraise\fR
.IP
In \fB-ncache\fR mode, do not assume that moving a window
will cause the window manager to raise it to the top
of the stack. The default is to assume it does, and
so at the beginning of any wireframe, etc, window moves
the window will be pushed to top in the VNC viewer.
.PP
\fB-ncache_no_dtchange\fR
.IP
In \fB-ncache\fR mode, do not try to guess when the desktop
(viewport) changes to another one (i.e. another
workarea). The default is to try to guess and when
detected try to make the transistion more smoothly.
.PP
\fB-ncache_no_rootpixmap\fR
.IP
In \fB-ncache\fR mode, do not try to snapshot the desktop
background to use in guessing or reconstructing window
save-unders.
.PP
\fB-ncache_keep_anims\fR
.IP
In \fB-ncache\fR mode, do not try to disable window
manager animations and other effects (that usually
degrade ncache performance or cause painting errors).
The default is to try to disable them on KDE (but not
GNOME) when VNC clients are connected.
.IP
For other window managers or desktops that provide
animations, effects, compositing, translucency,
etc. that interfere with the \fB-ncache\fR method you will
have to disable them manually.
.PP
\fB-ncache_old_wm\fR
.IP
In \fB-ncache\fR mode, enable some heuristics for old style
window managers such as fvwm and twm.
.PP
\fB-ncache_pad\fR \fIn\fR
.IP
In \fB-ncache\fR mode, pad each window with n pixels for the
caching rectangles. This can be used to try to improve
the situation with dropshadows or other compositing
(e.g. MacOS X window manager), although it could make
things worse. The default is 0 on Unix and 24 on
MacOS X.
.PP
\fB-wireframe\fR \fI[str],\fR \fB-nowireframe\fR
.IP
Try to detect window moves or resizes when a mouse
