我是用的ubuntu 8.04，這裡並不打算講xorg.conf 如何修改 驅動如何裝，其實很多在ubuntu裡也都幫你自動設定好了，只是說一下令我新奇的發現。
今天本來是想把觸控板的滾**能開啟，卻無意間發現了synclient功能的強大，其中就有可以設定雙指觸控對應滾輪的操作。
在終端敲下：synclient -l
還有更多方便的設定可供選擇

Synaptics車用指紋感測器
或許在不久之後，我們駕駛各類汽車和卡車時再也不需要實體鑰匙了。日前synaptics公司宣布，將很快把natural id指紋感測器整合到車輛當中。這個感測器針對的不是個人使用者，未來幾年汽車製造商將把它們安裝在車輛上，你將通過這種感測器完成各種各樣的功能。現在synaptics想要通過指紋識別技術...
