SL410 安裝Ubuntu 10.04 - 運行時 畫面會有閃動

原本安裝windows xp不會
安裝Ubuntu 10.04卻會有類似更新畫面的閃動
頻率挺頻繁的十幾分鐘一次 （估計值）

後來把電池移除
只用Ac adapter供電
就很少發生
一天一次（估計值）

修改sl410 trackpoint 小紅點的靈敏度 under 10.04

Follow在ubuntu 10.4中調整trackpoint的sensitivity作設定


發現my系統的speed and sensitivity跟作者的不同

nelsonchung@ubuntu:/sys/devices/platform/i8042$ find . -type f -name speed
./serio4/serio5/speed
nelsonchung@ubuntu:/sys/devices/platform/i8042$ find . -type f -name sensitivity
./serio4/serio5/sensitivity

以下是我的修改內容
將以下內容修改到/etc/udev/rules.d/10-trackpoint.rules

SUBSYSTEM=="serio", DRIVERS=="psmouse"

WAIT_FOR="/sys/devices/platform/i8042/serio4/serio5/speed", ATTR{speed}="120"
WAIT_FOR="/sys/devices/platform/i8042/serio4/serio5/sensitivity", ATTR{sensitivity}="245"


ps:
http://zh.wikipedia.org/zh/Udev

Ubuntu系統支援4G以上的ram - PAE(physical address extension)

請安裝以下套件

sudo apt-get install linux-headers-server linux-image-server linux-server

可以使用free -m看memory
