display problem

[pkaplan1 at comcast.net]

I am running kubuntu 10.10/KDE SC 4.6 on a Thinkpad T400 with Intel graphics (GMA 4500). 


I configured my desktop with an external monitor attached and run an extended virtual desktop spanning both monitors. I have a panel on the laptop monitor only and different wall papers on each monitor with folderview set to display the Desktop folder, but with files displayed on one monitor and folders on the other. 


When I boot the machine without the external monitor, it seems as if the external monitor display is rendered on top of the internal monitor display. Only the folders from the external screen are visible and the panel (which lives on the laptop monitor) is hidden. All windows open to the internal monitor display and are thus hidden and can't be accessed. The same thing happens if I use xrandr to turn off the external monitor and display everything on the laptop monitor. 


This problem has to do with KDE, not X or xorg.conf, since LXDE behaves normally, showing only a small screen on the single monitor or a large screen when the external monitor is detected. Also changing xorg.conf doesn't fix anything. 


The only solution I see is to use a cloned display or turn off the laptop monitor when using KDE or switch to another display manager. 


HELP!
