Configure your system to have x11vnc running at startup.

Ubuntu 15.04 – Configure your system to have x11vnc running at startup.

Hello World,

If you are following us, you probably remember that we wrote already a post about this topic (see Ubuntu 14.10 – Configure your sytem to have x11vnc running at startup). Since Ubuntu 15.04 is using systemd, the instructions found in the previous post are not applicable anymore. Some of our readers had issues after upgrading to Ubuntu 15.04. The x11VNC is not running at startup anymore.
