DPMS(4)		       FreeBSD Kernel Interfaces Manual		       DPMS(4)

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.

SEE ALSO
     acpi_video(4)

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.
