How do I do the actual switching from one display to another?

I'm not sure if this is a bug in Xfce. The other day, I forgot to switch 
from DVI-0 to LVDS-0 before undocking, so the screen was blank when I 
opened the laptop. Pressing fn+f7 had no effect since 
xfce4-display-settings -m only shows up if more than one display is 
connected. So I invoked a script (bound to a key) that calls xrandr, 
which brought the display back. However, Xfce didn't know about the 
newly set resolution: On the screenshot attached, the area outside the 
wallpaper was not visible.
