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
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.
