系统设置中缺少触摸板选项

我有一台运行 14.04 版的 Razer Blade 14"。当我启动计算机时，触摸板选项很少出现在设置中。当它们出现时，它工作正常。然而，通常情况下，设置不在那里，两指滚动、打字时禁用等功能不起作用。我似乎找不到它何时起作用或不起作用的任何规律，尽管它起作用的频率并不比起作用的频率高多少。触摸板通常仍然可以工作。我可以用物理按钮和点击来移动它和单击它，只是两指滚动和其他功能不起作用（当它们不起作用时，它似乎也会影响灵敏度）。

这是 xinput 列表的输出，它目前不起作用。

更新：我能够使用如下所述的驱动程序使其更正确、更一致地工作：http://zhehou.blogspot.com/2014/07/razer-blade-14-touchpad-multitouch-in.html

不过，每次重启后它都不起作用。当我在重启之前运行 make install 和 depmod -a 时，它似乎更经常地起作用。我无法让链接中的修复程序起作用，以允许它在全新启动时工作，尽管它似乎在重启后更经常地起作用，尽管即使这样也并非总是如此。
