I am having a similar problem to this on the Macbook Pro 11,1 (Retina) on a tabula rasa install of 16.04 LTS). However this resolution switch only occurs on the first time (from boot-up). Each subsequent times, it maintains the correct resolution and remembers the user's wallpaper.
After a reboot, the wallpaper is set to default (purple background) instead of remember the user's last used wallpaper.
