Set the order of multiple screens

  • 772

Is there a standard way to set the order of multiple screens in Ubuntu 19.10?

I have used the "right click on the desktop" > "Display Settings" to set the order of my 3 screens. It works well after login to the system. But before the login the order is different to this setting here. Hence, my login window is not on the center screen and rather in my case on the right screen.

Is there a way to apply the same screen settings of the desktop to the screen settings of the login?

  1. I do this with a script using 

    xrandr --output eDP  --auto --output HDMI-A-0 --primary --left-of eDP

    here HDMI-A-0 us set as primary and to the left of the secondary screen eDP

    I get the monitor names from 

    xrandr

    add that to startup applications (power key, startup, add ) and if that doesnt work, make it a script and add it in startup applications 

    bash "wherever/whatever/whatisname.sh"

    you could also do a keyboard shortcut to that script for manual monitor placement.

    and you will need to set the third monitor to the left (or right) of another monitor. if that works, join above xrandr command with && for the second placement.
