.SH DESCRIPTION
|
|
.LP
|
|
The DPMSSetTimeouts function permits applications to set the timeout values
|
|
used by the X server for Display Power Management Signaling (DPMS) timings.
|
|
.LP
|
|
The value \fIstandby\fP is the amount of inactivity time, in seconds, before
|
|
standby mode is invoked. The actual
|
|
effects of this mode are dependent 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.
|
|
.LP
|
|
The value \fIsuspend\fP 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.
|
|
.LP
|
|
The value \fIoff\fP 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 horizontal 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.
|
|
.LP
|
|
Chronologically, \fIstandby\fP mode occurs before or simultaneously with
|
|
\fIsuspend\fP mode, and
|
|
\fIsuspend\fP mode must occur before or simultaneously with \fIoff\fP 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.
