Please reassign to a general X bug. This problem can be caused in Gnome too. To make it happen quickly, just adjust the screen brightness using the Power manager applet in either KDE or Gnome on an Acer Aspire 9300 laptop (uses nvidia GeForce Go 7300).
WARNING! Once this is done, your system will become unusable as you will not be able to enter any console or enter console commands from X.
