DPMSSetTimeouts(3)						    X FUNCTIONS 						DPMSSetTimeouts(3)

NAME

       DPMSSetTimeouts - permits applications to set the timeout values used by the X server for DPMS timings

SYNOPSIS

       cc [ flag ... ] file ... -lXext [ library ... ]
       #include <X11/extensions/dpms.h>

       Status DPMSSetTimeouts
	      (
		    Display *display,
		    CARD16 standby,
		    CARD16 suspend,
		    CARD16 off
	      );

ARGUMENTS

       display
	      Specifies the connection to the X server

       standby
	      Specifies the new standby timeout in seconds

       suspend
	      Specifies the new suspend timeout in seconds

       off    Specifies the new off timeout in seconds

DESCRIPTION

       The  DPMSSetTimeouts  function  permits	applications to set the timeout values used by the X server for Display Power Management Signaling
       (DPMS) timings.

       The value standby is the amount of inactivity time, in seconds, before standby mode is invoked. The actual effects of this mode are  depen-
       dent  on  the characteristics of the monitor and frame buffer card. Standby mode is implemented by shutting off the horizontal sync signal,
       and pulsing the vertical sync signal. Standby mode provides the quickest monitor recovery time.	Note also  that  many  monitors  implement
       this mode identical to suspend mode.  A value of zero disables the standby mode.

       The  value  suspend  is	the  amount of time of inactivity, in seconds, before the second level of power savings is invoked. Suspend mode's
       physical and electrical characteristics are implementation defined. For DPMS compliant hardware, setting the suspend mode is implemented by
       pulsing the horizontal sync signal and shutting off the vertical sync signal.  In general, suspend mode recovery is considered to be slower
       than standby mode, but faster than off mode. However it may vary from monitor to monitor.  As noted above,  many  monitors  implement  this
       mode identical to the standby mode.  A value of zero disables this mode.

       The  value  off	is  the  amount of time of inactivity,in seconds, before the third and final level of power savings is invoked. Off mode's
       physical and electrical characteristics are implementation defined. In DPMS compliant hardware, it is implemented by shutting off both hor-
       izontal	and  vertical  sync  signals,  resulting in powering down of the monitor.  Recovery time is implementation dependent.  Usually the
       recovery time is very close to the power-up time of the monitor. A value of zero disables this mode.

       Chronologically, standby mode occurs before or simultaneously with suspend mode, and suspend mode must occur before or simultaneously  with
       off  mode.   Therefore, non-zero mode timeout values must be greater than or equal to the timeout values of earlier modes.  If inconsistent
       values are supplied, a BadValue error will result.

RETURN VALUES

       TRUE	      The DPMSSetTimeouts function returns TRUE when the function has succeeded.

ERRORS

       BadValue       An argument is out of range.

NAME

       sys_attrs_pwrmgr - pwrmgr subsystem attributes

DESCRIPTION

       This reference page lists and describes attributes for the Power Manager (pwrmgr) kernel subsystem. To change these attributes so that they
       take effect each time you boot the system, you create a stanza file with the attribute settings you want and then use the sysconfigdb  com-
       mand  to  update  the  system configuration database with the information in this file. See the EXAMPLES section for more information about
       this process.  Refer to the sys_attrs(5) reference page for an general introduction to the topic of kernel subsystem attributes.

	      A value that enables (1) or disables (0) CPU slowdown after the CPU becomes idle.

	      A value that enables (1) or disables (0) all power management functions (for CPU, disks, and graphics hardware).	The number of min-
	      utes to wait before powering down registered disks after they become idle.

	      A value that enables (1) or disables (0) disk spindown after registered disks become idle.

	      The  number  of  minutes	before entering DPMS off mode after display hardware has become idle. If you specify 0 for this attribute,
	      DPMS off mode is disabled.

	      A value that enables (1) or disables (0) Display Power Management Signaling (DPMS) modes for graphics display hardware.

	      The number of minutes before entering DPMS standby mode after display hardware has become idle. If you specify 0 for this attribute,
	      DPMS standby mode is disabled.

	      The number of minutes before entering DPMS suspend mode after display hardware has become idle. If you specify 0 for this attribute,
	      DPMS suspend mode is disabled.

EXAMPLES

       The following example shows a sample stanza file named power_mgr.stanza:

       pwrmgr:
			 default_pwrmgr_state=1
			 cpu_slowdown=1
			 disk_spindown=1
			 disk_dwell_time=20
			 graphics_powerdown=1
			 graphics_standby_dwell=5
			 graphics_suspend_dwell=10
			 graphics_off_dwell=15

       This file: Enables power management in general, plus  all three of the power management options for idle hardware (CPU slowdown, disk spin-
       down, and DPMS modes for graphics displays) Specifies a wait of 20 minutes before spinning down a disk after it has become idle Specifies a
       wait of 5, 10, and 15 minutes before entering DPMS standby, suspend, and off modes,  respectively,  after  graphics  display  hardware  has
       become idle

       See stanza(4) for more information about stanza files.

       The  following command updates the /etc/sysconfigtab database with the information in the stanza file: # sysconfigdb -a -f power_mgr.stanza
       pwrmgr

       See sysconfigdb(8) for more information about using this command to update the system configuration database.
