Further description to the problem, hope it will shine more light to the problem.
When the LCD monitor go to sleep, the monitor will turn off, after 2 second the monitor back-lid will turn back on, it is more like the system is showing a black screen. After another 15 second, the mouse pointer will appear. So there is a mouse pointer against a black background. I try to use Ksnapshot to capture the mouse pointer against a black background screen. Interestly in the captured screen shot, only has black screen, no mouse pointer.
