VNC

Remote administration using VNC from boot with Linaro
In this page we see how to use setup our Linux bootable image so that it is automatically accessible remotely through VNC from the login-screen. The following instructions have been tested with Ubuntu/Linaro. Other GNU/Linux distributions may require modifications.


 * Run the commands

sudo apt-get update sudo apt-get install lightdm-gtk-greeter x11vnc sudo x11vnc -storepasswd /etc/x11vnc.pass

The first command will update the package list (requires Internet connection) and the second command installs two packages. The third command creates a password for VNC.


 * Then, edit /etc/lightdm/lightdm.conf with

sudo nano /etc/lightdm/lightdm.conf

[SeatDefaults] greeter-session=lightdm-gtk-greeter user-session=Lubuntu
 * and adjust as follows to disable autologin / enable login screen for VNC
 * 1) autologin-user=linaro


 * Note, that you can select whether you want to enable autologin. The above example disables autologin to get the login-session-start event for VNC. To enable, remove the comment # character from the start of the line. But Re-enabling autologin will prevent VNC from launching automatic.

sudo nano /etc/init/x11vnc.conf start on login-session-start script /usr/bin/x11vnc -xkb -auth /var/run/lightdm/root/:0 -noxrecord -noxfixes -noxdamage -rfbauth /etc/x11vnc.pass -forever -bg -rfbport 5900 -o /var/log/x11vnc.log end script
 * Now create a new file with
 * and add the following content:


 * Save and exit. Then, reboot and you should be able to login with any VNC-viewer (like remmina in Ubuntu) with your given password @ port 5900 and can login with any user available.
