x11vnc's use of the DAMAGE extension: 1) significantly
|
|
|
|
|
reduces the load when the screen is not changing much,
|
|
|
|
|
and 2) detects changed areas (small ones by default)
|
|
|
|
|
more quickly.
|
|
|
|
|
.IP
|
|
|
|
|
Currently the DAMAGE extension is overly conservative
|
|
|
|
|
and often reports large areas (e.g. a whole terminal
|
|
|
|
|
or browser window) as damaged even though the actual
|
|
|
|
|
changed region is much smaller (sometimes just a few
|
|
|
|
|
pixels). So heuristics were introduced to skip large
|
|
|
|
|
areas and use the damage rectangles only as "hints"
|
|
|
|
|
for the traditional scanline polling. The following
|
|
|
|
|
tuning parameters are introduced to adjust this
|
|
|
|
|
behavior:

Set the largest DAMAGE rectangle area \fIA\fR (in

|
|
|
|
|
the rectangle will be copied from the framebuffer
|
|
|
|
|
(slow) no matter what. Set to zero to trust *all*
|
|
|
|
|
rectangles. Default: 20000

|
|
|
scanline repeat cycle time (32 iterations). The default

(1.0) should give no painting problems. Increase it if
|

there are problems or decrease it to live on the edge
