qyang@lubuntu-laptop:~$ apt-cache search autocutsel
autocutsel - Keep the X clipboard and the cutbuffer in sync
Got tightvnc work on lubuntu after changing xstartup file
./vnc/xstartup file is configured as follows [11] :#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey -cursor_name left_ptr
autocutsel -fork
lxsession -s Lubuntu -e LXDE
x11vnc is slower. [7] [8] tightvncserver is suggested and faster. [8] vnc4server was discussed a lot.
x11vnc is different from xvnc(tightvnc, tigervnc). The latter support multiple sessions. Also, seems x11vnc is slower than xvnc.[7]
x11vnc offers better security focus ( can be secured with SSH or SSL.) but it's known to be slower. [8]
vino and x11vnc in Ubuntu [9]
