Connect LG Optimus 2X to Windows/Ubuntu via Bluetooth/Data Cable to use Internet
EasyTether is the easiest way to share your phone wireless internet with your computer. You install the program on your phone, set up the drivers (which can be found here) and run. To enable easytether, check the top box on the application screen. Easy as that!

After you install the drivers:

For Ubuntu:


start a terminal window
type easytether connect
it will connect, and give you another command that you can type into another terminal window to see status information about your connection.


NOTE: the original terminal window you open (that you typed easytether connect into) must stay open while you are using the connection

For Windows:


right click the Easytether logo in the taskbar (lower right hand side, by the clock)
choose connect via (big number here)
you're connected!
