我有一台运行最新 Ubuntu 15.04 的 Dell Latitude E6410（请参阅本问题末尾的详细信息）。我认为我在 TrackPoint 方面遇到了与以下所述的相同问题：
对该问题留下的评论是： 戴尔与联想的指点杆/乳头/指点杆鼠标驱动程序？
这表明
Dell Latitude 上的 Glidepoint 触摸板/指点杆设置
但是阅读该链接让我感到困惑，如何从 Ubuntu 存储库实际安装该软件包（我的意思是安装它时不需要做太多工作，例如从源包下载和构建）。
在网上搜索节目http://www.ubuntu.com/certification/catalog/component/input/4932/input%3AAlpsPS/2ALPSGlidePoint/ 上面说的是经过认证的笔记本电脑。E6410 未列出。
搜索 glidepoint 包显示：
https://launchpad.net/ubuntu/+source/touchpad-glidepoint
其中说明：
Ubuntu 中当前没有此源包的发布版本。
这是正确的安装包吗？根据上述评论，我得出“否”的结论。如果这不是正确的包，我应该使用哪一个？如果它是正确的包，那么为什么会出现“没有当前版本”的消息？

而且这并没有显示任何允许我控制 TrackPoint 行为的小部件，这让我相信缺少了一些东西，因此，我需要寻找并安装一些特殊的软件包：
