i have notebook and external display connected via VGA port. I am using kscreen
for display management. When I connect external display everything works well
(notebook display switched off and all screen is on external display).

But when I unplug VGA cable, display on notebook stays black. Workaround is run
xrandr (without parametrs) in console for flushing cache.

I have suspicion, that raden driver don't generate Xrandr event (message) when
external display is unplugged from VGA port.

GPU: ATI Radeon X1400
Driver: OS Radeon (xf86-video-ati 1:7.1.0-3)
Distro: Arch Linux
KDE: 4.10.4
Kscreen: 1.0
