如何在Debian Wheezy KDE中启用触摸板滚动和点击？

我正在尝试使用笔记本电脑的触摸板打开滚动和点击操作（左右两个按钮都可以）。我在Debian 7.3（Wheezy）KDE桌面上，并且有一个Synaptic触摸板。我的笔记本电脑是2007年的老式HP机型，因此不支持多点触控。作为root，我创建了一个/etc/X11/xorg.conf.d/synaptics.conf文件，并在下面复制了该文件。然后在Konsole中，我给出synclient -l并返回了以下代码：

这是内容 /etc/X11/xorg.conf.d/synaptics.conf

apt-get install server-xorg-input-synaptics创建synaptics.conf文件后，我已经安装并重新启动了系统，但没有任何更改。

我应该怎么做才能使其正常工作？
