When I use xrandr to enable and disable monitors, the xfce4-panel does not recognize the change.

Use case environment:
When I have 2 monitors, I have the panel set to show on monitor 2 in the panel manager (monitor 2 is my laptop screen according to xfce). I use an external DVI monitor at work with a docking station and an external VGA monitor at home connected to the laptop.



Reproducible: Always

Steps to Reproduce:
Use case #1:
Only laptop (LVDS) is enabled. Panel is on bottom of screen
run "xrandr --output TMDS-1 --auto --above LVDS"
panel is now on monitor 1 (the external TMDS-1) and maximized applications on monitor 2 (LVDS) have a gap at the bottom the height of the panel
opening the panel manager shows that it thinks there is only 1 monitor (there is no monitor section)
run "xfce4-panel -r" fixes the issue

Use case #2:
laptop (LVDS) and external (TMDS-1) are enabled. Panel is on bottom of monitor 2
run "xrandr --output TMDS-1 --off"
panel is now missing
run "xfce4-panel -r" fixes the issue




running "xfce4-panel -r" is not a good workaround as many tray resident programs do not correctly re-insert their icons in the tray after the restart (especially KDE applications like amarok, klipper and knotes).
