I just have Ubuntu server and can ssh to it but it also has a keyboard and a screen thought HDMI text only.
I can press print screen key but not sure if it saved it any place.
Looked on Google and all have the desktop even though I look for server.
Maybe the only way is hook up a video box though HDMI to record the screen? Or is there away to just press print screen and a .jpg will be in your home folder?
