set desktop sharing if it is used as host
>$ sudo apt-get install vino
set vnc4server for connecting ubuntu from other system terminal (e.g. windows / ubuntu)
>$ sudo apt-get install vnc4server
>$ sudo apt-get install xrdp

>$ sudo apt-get install x11vnc
>$ sudo apt-get install xrdp
>$ sudo vi /etc/init/x11vnc.conf
start on login-session-start
script
x11vnc -display :0 -auth /var/run/lightdm/root/:0 -forever -shared -bg -o /var/log/x11vnc.log -rfbport 5900 -tightfilexfer
end script
use remote desktop from rdp to vnc
use [tightvnc](https://raw.githubusercontent.com/ouiyeah/ubuntu/master/pkg/tightvnc-2.7.10-setup-64bit.msi) to copy and paste clipboard between windows and linux
use scp to copy files between linux systems and use [pscp](https://raw.githubusercontent.com/ouiyeah/ubuntu/master/pkg/putty.zip) to copy files from or to windows

>$ echo 'KERNEL=="ttyUSB[0-9]*", MODE="0666"' | sudo tee -a /etc/udev/rules.d/70-persistent-tty.rules
lookup and bind the device id
>$ udevadm info /dev/ttyUSB0 (e.g. USB0 ID_PATH=pci-0000:00:1a.0-usb-0:1.2:1.0)
>$ echo 'SUBSYSTEM=="tty", ENV{ID_PATH}=="pci-0000:00:1a.0-usb-0:1.2:1.0", SYMLINK+="alias_name(e.g.)"' | sudo tee -a /etc/udev/rules.d/70-persistent-tty.rules
