I just got a new monitor (Acer H236HL). It works with the computer I'm using now but it isn't working with my personal computer (Ubuntu 13.10)
I turned my computer off, unplugged the old monitor (Take note that the monitor was working prior to shutting off my computer) and put in my new Acer one via HDMI.
I booted my computer and turned on my monitor. My monitor searches for which connection (HDMI/DVI/VGA) is being used. It doesn't use any of them and says "No Signal" and then goes into sleep mode. If I turn the monitor on when not connected to my computer it says "Cable Not Connected". I try VGA and DVI and the same thing.
I try to put my old monitor back in and it wouldn't work either (It worked perfectly earlier) and it just says "No Signal". I assumed this would be an easy plug and play but I guess not.
