In your driver, call xf86DPMSInit to register your function with the X server. Then your function will be called whenever the X server wishes to change the screens power state. See xc/programs/Xserver/hw/xfree86/common/xf86.h and xc/programs/Xserver/hw/xfree86/common/xf86DPMS.c for xf86DPMSInit, and and xc/programs/Xserver/hw/xfree86/drivers/mga/mga_driver.c or must other drivers for examples of its use. -- Dr. Andrew C.
