NAME

     dpms — VESA BIOS DPMS driver

SYNOPSIS

     device dpms

DESCRIPTION

     The dpms driver uses the VESA BIOS to manage an external display during suspend and resume.
     When the machine suspends, the dpms driver turns the external display off.  When the machine
     resumes, it restores the display to its state when the driver was first loaded.

BUGS

     The VESA BIOS DPMS calls do not provide any way to identify a particular display or adapter
     to manipulate.  As a result, this driver may have unexpected results on systems with
     multiple displays and/or adapters.
