Under Ubuntu Gnome 14.04, Gnome 3.12, I'm running with a different from my maximum resolution. After login, the resolution is set fine, and when I log in after locking the machine, the resolution is fine.

After reboot or ask to change user, the resolution changes, making things jump around. I would like to fix that.

How can I change the resolution for the initial login screen, or change the resolution system wide?

I have tried combining this, this and this, editing my /etc/gdm/Init/Default (also tried /etc/gdm/PreSession/Default) by inserting

xrandr --output eDP1 --primary --mode 1920X1080

but that didn't work. It had an effect, but it didn't work.

I also tried generating my xorg.conf file and editing that with no avail. I'm not using a proprietary driver.
