Installing on a laptop with a broken screen - how can I duplicate the display to an external monitor rather than extending it before installation?

I am trying to install Ubuntu on my laptop which has a broken LCD.

I've plugged it into a monitor via HDMI but it is extending my screen instead of duplicating it, leading to the install icon being on the broken LCD and I'm assuming that the terminal windows I am trying to open are opening on there as well.

I've tried using FN+F# keys to no avail.

I think what you will want to do is to press your super_key + P

on your keyboard, your super key is likely the windows key.

every time you do it will cycle through

  • Extended display
  • Duplicate display
  • Display attached screen/projector only
  • Native (laptop/desktop) screen only

As noted in the second answer for this question How to have duplicate display on ubuntu 14.04 with gnome

let us know if that works for you.

After several reboots the installation window appeared on my external monitor, not 100% sure why but I'll take it as a victory, thanks for all the responses!
