[Tips] How to configure ThinkPad trackpoint in Linux?

最近對比了一下另外一台裝Windows XP的X61,驚覺在Linux上的trackpoint速度不是很快,也不夠靈敏,想要調整卻找不到在哪裡調,找到這篇發現直接寫入driver就可以了

預設設定是這樣的,

$ cat /sys/devices/platform/i8042/serio1/sensitivity 128
$ cat /sys/devices/platform/i8042/serio1/speed 97
$ cat /sys/devices/platform/i8042/serio1/press_to_select 0
$ cat /sys/devices/platform/i8042/serio1/upthresh 255

如果不是root而直接sudo可能會出現

bash: /sys/devices/platform/i8042/serio1/sensitivity: Permission denied

遇到這樣就把指令寫成.sh然後再sudo執行就沒問題了,最後我改成

#!/bin/sh
echo -n 160 > /sys/devices/platform/i8042/serio1/sensitivity                                                                 
echo -n 120 > /sys/devices/platform/i8042/serio1/speed
