Answer 1

如果您的平台上有可用的版本（大多数Linux平台都可以），您可以考虑使用DBus来获取类似的通知，并且Qt通过各种类内置了DBus支持。

Answer 2

since you are already working with Qt in a Linux environment, using KDE4 libraries should be easy to understand because they are built on top of Qt and follow similar design principles. With KDE4, you have access to the Solid library for managing system hardware information. This tutorial can help you to get introduced.
