So this is an issue of both my monitors ARE working, but they're being treated as if they're one monitor with a resolution of 3840x1200 * 1 instead of 1920x1200 * 2. I'm looking for the standard setup of each monitor acting independently.

When I open System Settings > Displays it only shows 1 * Dell 24". I'm running an HP EliteBook 1040 plugged into a dock with 2 display ports. I'm converting both display ports to DVI into the 2 monitors. I'm also not using my laptop screen. The laptop is closed. If I select a resolution of 1920x1200 it mirrors the display on both but the Display window isn't reporting 2 monitors exist, even if I click Detect Displays.

I know just enough to look at all this, but not enough to change any settings to fix this.

  • Are you looking to mirror your desktop, or extended desktop? – j0h Mar 16 '15 at 22:39
  • I'm wanting to extend them. – jtsmith1287 Mar 17 '15 at 2:21
  • Try this command xrandr --output eDP1 --left-of LVDS1 – Sergiy Kolodyazhnyy Mar 18 '15 at 23:10
  • what happens if the laptop were open? – j0h Mar 19 '15 at 12:52
  • I ran xrandr --output eDP1 --left-of LVDS1 and it didn't do anything. I realized that for some reason ubuntu is thinking that all 3 monitors (includes the built in laptop display I'm not using) are the same display. The little tags that identify the moniters in the top left corner of the displays are all stacked on the far left display. – jtsmith1287 Mar 20 '15 at 16:40

The issue was the dual display ports. Ubuntu saw those as a single output. Switching to a DP & VGA resolved the issue.
