Public bug reported:

Binary package hint: xorg

I have an external monitor attached to my laptop through a docking station. I use Ubuntu Lucid Lynx.
I work only with the external monitor and the laptop monitor should be switched off. This can easily be done with gnome-display-properties.
But sometimes (after a reboot or even during normal working), the monitor settings are reset such that the laptop monitor is turned on again. This implicates, that the panel is moving on the laptop screen, which is closed. Without a panel it is hard to run gnome-display-properties to change the display settings again (but I can run it with Alt-F2). 
In Ubuntu Karmic, I had no problems. How do I disable this new "feature"?
It is hard to say how to reproduce the problem, because it is not regularly happening. Sometimes after a reboot, sometimes when I start a video, sometimes after a screensaver period, but not always after these actions.
