I am a Linux novice. I recently created a dual boot of Windows 10 and Linux Mint 19.1. In windows 10 mode, both my HDMI and VGA monitors are identified. In Linux mode, only the HDMI monitor is identified. If I boot from the installation disk with the HDMI monitor disconnected, VGA works fine. If I boot from my installed instance with only the VGA monitor attached, I get no video output. If I live switch to HDMI, I get video output. I've searched the world over but could not find anyone else having this issue. Did I muck up the installation?

Sorry, I'm not very knowledgeable about this kind of thing but I switched to a DVI cable which I had laying around from the VGA cable I've been using for years and everything worked fine.

In my case it was the cable being only partly connected. Connecting it securely fixed the issue for me.
