-<title>Overview</title>
-
-<para>This extension provides X Protocol control over the VESA Display
-Power Management Signaling (DPMS) characteristics of video boards
-under control of the X Window System.
-</para>
-
-<para>
-Traditionally, the X Window System has provided for both blanking and
-non-blanking screen savers. Timeouts associated with these built-in
-screen saver mechanisms are limited to idle (dwell) time, and a change
-timeout that specifies the change interval for non-blanking screen savers.
-</para>
-
-<para>
-The United States' Environmental Protection Agency (EPA) Energy Star program
-requires that monitors power down after some idle time by default.
-While it is possible to simply overload the existing screen saver timeouts,
-this solution leaves the non-privileged user little to no control over
-the DPMS characteristics of his or her system. For example, disabling
-DPMS would require some unintended side effect in the core screen saver,
-such as disabling the changing of a non-blanking screen saver. Providing
-clients with this control requires an extension to the core X Window System
-Protocol, and this extension seeks to fill this gap.
-</para>
-
-<para>
-There are four power levels specified by the Video Electronics Standards
-Association (VESA) Display Power Management Signaling (DPMS) standard.
-These are mapped onto the X DPMS Extension like this:

-The DPMSSetTimeouts function permits applications to set the timeout values
-used by the X server for DPMS timings.
-</para>
-
-<para>
-The value <emphasis remap='I'>standby</emphasis> is the amount of time of
-inactivity in seconds before standby mode is invoked. The actual effects of
-this mode are implementation defined, but in the case of DPMS compliant
-hardware, it 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 identically to suspend mode. A value
-of zero disables this mode.
-</para>
-
-<para>
-The value <emphasis remap='I'>suspend</emphasis> 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, but in DPMS compliant hardware, results in the pulsing of the
-horizontal sync signal, and shutting off of the vertical sync signal.
-Suspend mode recovery is considered to be slower than standby mode, but
-faster than off mode, however this is monitor dependent. As noted above,
-many monitors implement this mode identically to standby mode. A value of
-zero disables this mode.
-</para>
-
-<para>
-The value <emphasis remap='I'>off</emphasis> 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, but in DPMS compliant hardware, is implemented by
-shutting off both horizontal and vertical sync signals, resulting in
-the power-down of the monitor. Recovery time is implementation dependant,
-but frequently is similar to the power-up time of the monitor. A value
-of zero disables this mode.
-</para>
-
-<para>
-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.

+The DPMSSetTimeouts function permits applications to set the timeout values

+<para>
+The value <emphasis remap='I'>standby</emphasis> is the amount of time of
+inactivity in seconds before standby mode is invoked. The actual effects of
+this mode are implementation defined, but in the case of DPMS compliant
+hardware, it 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 identically to suspend mode. A value
+of zero disables this mode.
+</para>
+
+<para>
+The value <emphasis remap='I'>suspend</emphasis> 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, but in DPMS compliant hardware, results in the pulsing of the
+horizontal sync signal, and shutting off of the vertical sync signal.
+Suspend mode recovery is considered to be slower than standby mode, but
+faster than off mode, however this is monitor dependent. As noted above,
+many monitors implement this mode identically to standby mode. A value of
+zero disables this mode.
+</para>
+
+<para>
+The value <emphasis remap='I'>off</emphasis> 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, but in DPMS compliant hardware, is implemented by
+shutting off both horizontal and vertical sync signals, resulting in
+the power-down of the monitor. Recovery time is implementation dependant,
+but frequently is similar to the power-up time of the monitor. A value
+of zero disables this mode.
+</para>
+
+<para>
+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.
