摘要

一直到现在, Solaris都没有一个方便的应用程序来允许用户管理和监控电源的消
耗和电池状态。特别是对笔记本电脑用户,他们不知道如何像Window或者Linux那样
进行电源管理。尽管现在电源状态的Applet已经在Nevada中了,但是仍然不能用它
来控制电量不足或者用户合上笔记本后应该执行的动作。在Solaris 10中,我们提
供dtpower来帮助用户进行参数配置。但是,这些配置已经不够了。我们经常听到用
户抱怨Solaris消耗了太多的电量而且不能挂起或者休眠。如果要向用户提供一个
好的桌面系统,我们必须解决这一问题。

在这个演讲中, 演讲者从桌面的角度介绍了电源管理的方案。首先,他描述了一些
有关电源管理的背景信息和Solaris的电源管理框架。然后,他介绍了和电源管理相
关的一些标准和概念。最后,他主要介绍了GNOME Power Manager是什么,它的结构
和如何将它从Linux移植到Solaris中。

Until now, Solaris doesn't have a convenient desktop application which
enables users to manage and monitor power consuming and battery status.
Especially for laptop users, they don't know how to manage their power
consuming easily like Windows and Linux. Though battery status applet
has been put into Nevada, they still can't control what the system
should do if the battery power is critically low or what should be done
if they close the lid. In Solaris 10, we provide dtpower to help users
configure some power parameters. However, nowadays the features it
provides are obviously no longer sufficient. We often hear users
complaining that the Solaris consume much battery power and it can't
suspend/hibernate. To offer an excellent desktop for users, we must
solve this problem.

In this presentation, the lecturer introduces the power management
solution in Solaris from desktop perspective. First, he describes some
background information about power management and Solaris Power
Management framework. Then he introduces some concepts regarding to
power management. Lastly he introduces what GNOME Power Manager is, its
architecture and how it is ported to Solaris from Linux.
