Centos disable notebook touchpad

I installed a pair of systems in my laptop at home, and found that the touchpad was annoying and disabled!

1. Install a small artifact

yum install xorg-x11-apps

2. view the hardware ID to enable or disable the command.

[[email protected] yum.repos.d]# xinput list? Virtual core pointer                        id=2    [master pointer  (3)]?   ? Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]?   ? 2.4G Gaming Dongle                          id=9    [slave  pointer  (2)]?   ? Macintosh mouse button emulation            id=15    [slave  pointer  (2)]?   ? SynPS/2 Synaptics TouchPad                  id=16    [slave  pointer  (2)]? Virtual core keyboard                       id=3    [master keyboard (2)]    ? Virtual core XTEST keyboard                 id=5    [slave  keyboard (3)]    ? AT Translated Set 2 keyboard                id=6    [slave  keyboard (3)]    ? 2.4G Gaming Dongle                          id=7    [slave  keyboard (3)]    ? Namuga 1.3M Webcam                          id=8    [slave  keyboard (3)]    ? Sleep Button                                id=10    [slave  keyboard (3)]    ? Power Button                                id=11    [slave  keyboard (3)]    ? Lid Switch                                  id=12    [slave  keyboard (3)]    ? Video Bus                                   id=13    [slave  keyboard (3)]    ? Power Button                                id=14    [slave  keyboard (3)]

From the result, we can see that touchad to id = 16

3. Disable!

xinput set-int-prop 16 "Device Enabled" 8 0

4. If necessary, you can use this command to enable

xinput set-int-prop 16 "Device Enabled" 8 1
