[PLUG] problems w/ desktop ubuntu 14.04 machine

[Michael Barnes]

If you chose HDMI input on your monitor, and you are connected to the VGA
port, you will not see anything. This has nothing to do with your computer.
Use the "Input" or "Source" button on your monitor to select the VGA input.
That should get you to seeing the computer. Once you get that, you can work
on the booting issue.

Keep us posted.
