I have a laptop with an absolutly useless monitor (well, probably video card), so I put an Ubuntu 14.04 server on it. Of course if I turn it on, the monitor still turns on and blinks in vivid colors, which is annoying and a waste of electricity. How can I disable the monitor via the commandline, so it will not get powered on? Possible the videocard as well, since that is also useless.I have only found answers related to the X11-server-utils, but those don't even find the monitor (not really suprising, as I can only connect through ssh).
