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.
