I've inherited a server running on Ubuntu which has a keyboard connected, but no monitor.
Now there's been a network problem and I'm currently unable to connect via ssh (not even ping works). Still, calculations started by someone else might be running. For diagnosis, I plugged a monitor to vga, but this monitor gets no signal and stays black.
How can I activate the monitor? I don't need a GUI, seeing bash would already be OK.

Pressing a key on the keyboard may take the display out of sleep mode and cause something to appear on the screen. Also, try switching virtual terminals using ctrl-alt-f1, ctrl-alt-f2, etc.

I had this same problem. My issue was that HDMI cable was unidirectional, there's one way to plug it in from monitor to computer. Try swapping the cable (if you're still working on this 4 years after asking). :)
