System info: Ubuntu Desktop 16.04.1 LTS
Dual 1920x1200 monitors (one HDMI, on mini-DP)
When using dual-monitors with a wallpaper set to span, Ubuntu does not correctly display the wallpaper at the login screen or at the lock screen. Is there a way to correct this behavior? I have tried this with several wallpapers at 3840x1200 resolution and display type set to "span." How can this behavior be corrected?
