Ubuntu禁用触摸板

基于原文略有改动.
Run the following command in a terminal:

xinput list

You will get an output that looks like this:

cyper@zerorun:~$ xinput list
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ Logitech USB Receiver                   	id=11	[slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad              	id=14	[slave  pointer  (2)]
⎜   ↳ TPPS/2 IBM TrackPoint                   	id=15	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]
    ↳ Video Bus                               	id=7	[slave  keyboard (3)]
    ↳ Video Bus                               	id=8	[slave  keyboard (3)]
    ↳ Sleep Button                            	id=9	[slave  keyboard (3)]
    ↳ Logitech USB Receiver                   	id=10	[slave  keyboard (3)]
    ↳ Integrated Camera                       	id=12	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=13	[slave  keyboard (3)]
    ↳ ThinkPad Extra Buttons                  	id=16	[slave  keyboard (3)]
cyper@zerorun:~$ 

It displays all the input devices connected. Note that they all have an id. Since 14 is the id for my touchpad, running the following command will disable it.

xinput set-prop 14 "Device Enabled" 0

二

cyper@zerorun:~$ synclient|grep Touch
    TouchpadOff             = 2
cyper@zerorun:~$ 

turn off touch pad synclient TouchpadOff=1 turn it back on synclient TouchpadOff=0 This way even better.  

三

sudo apt-get install touchpad-indicator the good new is that touchpad-indicator is worked again in 11.10.
