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.
