Second Screen not deteced

Post by JeffYoo » Sun Sep 16, 2018 12:01 am

Hi all,

I have a fresh install of linux mint 18.3 and wanted to get my dual screen setup. On my second screen I can see the five dots you usually see when you boot linux, so I am confident it should be connected. I am very new to linux so it maybe an easy fix. All I really did was update my driver for my graphics card and updated my kernel. My second screen is using an old school VGA, and I noticed that under screen DVI-I-0 it says SignalFormat: VGA. Could this be the second monitor? and if so how do I configure it to work properly?

Here is the output of my xrandr --verbose

Did you connect the cable of second monitor to one of the nvidia card connectors or to the mainboard ?
