Ubuntu 16.04

This issue came up when connecting a VGA cable to our new Ubuntu 16.04 server.

Full Error Message:

 1: Auto Detect (Analog Input <VGA SYMBOL>)
 OUT OF RANGE SIGNAL
 CANNOT DISPLAY THIS VIDEO MODE, CHANGE
 COMPUTER DISPLAY INPUT TO 
 1680X1050@60Hz

I couldn't change the video display input because I had no way of seeing what's happening because of this video output error.

To resolve.

1. Get an Ubuntu Server 16.04 USB boot disk and plug it into the server
2. Make sure BIOS has USB boot disk at a higher priority than the HDD/SSD.
3. At options menu of the USB boot disk, select "Rescue a broken system"
4. Go through all the menu options selecting defaults until it asks you what to mount for root. Select the root partition from the HDD/SSD, not the USB disk.
5. Select the option for starting a shell.
6. While shell is started, mount the boot partition @ /boot. command for me was:

 $ mount /dev/sda1 /boot

7. Edit /etc/default/grub and uncomment section that contains:

#GRUB_GFXMODE=640x480

8. Lastly update grub with:

$ sudo update-grub

9. Reboot and it should output video
