I do not know if this is a Ubuntu problem or not, but Ubuntu recognizes my display that is connected via HDMI, but my second monitor that is connected via VGA cable is not recognized.

My setup:

  • Intel Core i5 x4

  • 8GB RAM

  • 1TB HDD

  • Intel HD Graphics

  • 1 HDMI port and one VGA port

What I've tried:

  • Trying a different VGA cable

  • Going to "Displays" program to fix it, but it does not see the VGA monitor

  • Reboot

  • Going to BIOS to see if I needed to enable multi-monitor support

Any help is appreciated, thanks. :)

Edit: When I shut it down and remove the HDMI cord, it boots up fine with VGA. But when I connect HDMI after the boot, it does not recognize it.

  • is this a laptop? often when a laptop would hane two external ports HDMI and VGA, but the video card can only support 2 of three at a time. – ravery Nov 24 '17 at 22:28
  • It is a desktop (Dell Inspiron 3668, to be exact). Thanks for your response. :) – Laqqe Nov 25 '17 at 0:40
