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.
