VIDEOCTL(1) BSD General Commands Manual VIDEOCTL(1)NAME
videoctl -- control video device
videoctl [-d device] -a
videoctl [-d device] name ...
videoctl [-d device] -w name=value ...
The videoctl command displays or sets various video system driver variables. If a list of variables is present on the command line, then
videoctl prints the current value of those variables for the specified device. If the -a flag is specified, all variables for the device are
printed. If the -w flag is specified videoctl attempts to set the specified variables to the given values. The -d flag can be used to spec-
ify an alternate video device. If -d is not specified, /dev/video0 is used.
/dev/video0 video device

The videoctl command first appeared in NetBSD 6.0.

acpi_video -- ACPI Video Extensions driver
This driver uses the ACPI Video Extensions to control display switching and backlight brightness. The availability of the sysctl(8) vari-
ables depends on the functions offered by the host's ACPI implementation.
The following sysctls are currently implemented, where <device> is crt, lcd, or tv:
Current state of the output device.
List of supported brightness levels.
Current brightness level of the device.
Preset brightness level to be used in full power mode.
Preset brightness level to be used in economy mode.
Defaults for these variables can be set in sysctl.conf(5), which is parsed at boot-time.
SEE ALSO acpi(4), loader.conf(5), sysctl.conf(5), sysctl(8)HISTORY
The acpi_video driver first appeared in FreeBSD 5.3.
The acpi_video driver was written by Taku YAMAMOTO <email@example.com>. This manual page was written by Mark Santcroos
Some systems only perform output switching via SMM even though they export the proper information via ACPI. On such systems, the proper
hotkeys or OEM driver (for example, acpi_toshiba(4)) must be used instead.

I'm writing a short script to check if a continuous port is running on a server.

I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
