Ubuntu 15.10 uses the native resolution of the screen by default. The native resolution on my laptop (3200*1800) is too big for the size of the screen (13"), leading to a very high pixel density, it makes it hard to use the UI.

I have changed the display settings after logging in, but when the computer boots up the resolution remains too high and it only changes after logging in. Terminal sessions (Ctrl+Alt+F1 and so on) also have this resolution after boot which makes the text unreadable.

I'd like to change (or limit?) the default resolution to 1920*1080 so that the login screen and terminal sessions are using that resolution right after the computer has booted up.

Only the default window manager is installed (lightdm + unity).
