Ubuntu 9.04 to 10.04 has application called vino. This is remote desktop application. But it has advance function compare to standard remote desktop that I usually use in System-Preferences-Remote Desktop menu.
Vino server could run in the background and put it in rc.local which will be executed every computer start. And it will display ubuntu login area so the remote control can choose which user he will be enter to.
But now the question is how to configure the setting of this vino, while the standard remote desktop application could be easily be set in the system menu.
We need to go to terminal session.
Then type this command
The vino will display the exact dialog box like standard remote desktop app.
Set the setting you want and click close. Now your vino will run even your standard remote desktop is off.
