panel does not pick up changes to the monitors with xrandr

[Andrew]

Binary package hint: xfce4-panel

Xubuntu Gutsy
xfce4-panel 4.4.1-1ubutu3

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.

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).

Thank you for your bug report. I'm marking this as triaged and forwarding upstream.

Does not pick up virtual display changes with --panning. Example is
xrandr --fb 1024x768 --output LVDS --mode 1024x600 --panning 0x768
which makes a 1024x768 panning display on a netbook that is 1024x600 in hardware. It works in that you can put windows in that space and it pans, but the panel does not notice and cannot be moved below the 600 line.
