I use a dell latitude E6420 with external dell monitor and connect them via a dock in my office. I use my external monitor as my primary display (where the launchers are) and the laptop built in display as extension (right of / left of - external monitor) When I suspend the machine (with dual monitors), detatch from dock and resume it, the laptop shows only the extended display. The launchers are not anymore. I believe XFCE still assumes that the external monitor is still available and the the primary display signals are sent there. It should automatically sense that the external monitor is not available and should have changed the display settings. This is a pain for me and I do not want to leave XFCE just for this :) otherwise xfce is great !
I think I had the same problem. Once the external monitor were turned off or unplugged. Since then, the launchers and the wallpaper disappear (according to the configuration, they should appear!). And the right-click on the desktop doesn't work. Furthermore, it doesn't recognize the resolution of my native display. However, it recognize automatically the resolution of the external monitors. After disconnect, it assume the resolution of the last external monitor enabled. It really seems like XFCE still assumes that the external monitor is still enabled. But I think that is not the point.

he problem doesn't happen with other users.
Problem is solved. Just typed "xfdesktop" at the terminal.
This is resolved. Since xfce4-settings 4.11.2, monitor connection events are acted upon, and the disconnection would cause the remaining laptop display to become the only active monitor. The issue Manuel reported seems to be with xfdesktop crashing. This may also be resolved in a later release of xfdesktop. If not, please report a new bug for xfdesktop.
