I would my server(X8DTG-DF) to act as a blackbox to the users and can be controlled by remote desktop or IPMI remote control only. I want the users will see nothing on the screen even when the users plug in the VGA cable, can I disable the VGA display on the server? make use of jumper or what?
You can disable onboard VGA with JPG1 jumper set to 2-3 pin, however, once you disable it, you cannot use console redirect in remote site as well.
