Enable and disable the notebook touchpad with the Ubuntu 14.04 shortcut key

Problem description:

Ubutnu does not support the keyboard driver of the notebook, especially the function key driver. My notebook is Toshiba Satellite P75A, and my computer is a new product of 14 years, even if the latest Ubuntu Desktop System has no corresponding driver, you have to make a shortcut key to control the touchpad. Who made us choose Linux.

Download, install, and configure Ubuntu 14.04.

Script code:

The solution is to use a Python script to automatically obtain the startup status of the current touchpad and respond accordingly.

Source code:

#! /Usr/bin/env python

Import OS

Def check_touchpad_state (dev_num ):
Dev_state = OS. popen ('xinput list-props % s' % str (dev_num ))
For lines in dev_state.readlines ():
If 'device enabled' in lines:
Sig = lines [-3:-1]. strip ()
Signal = int (sig)
Print ('signal now: % d' % signal)
Return signal


Def get_dev_num (dev_name = 'synps/2 Synaptics TouchPad '):
Dev_state = OS. popen ('xinput list ')
For lines in dev_state.readlines ():
If dev_name in lines:
Print (lines)
Station = lines. find ('Id = ')
Dev_num = lines [station + 3: station + 5]
Dev_num = int (dev_num)
Print ('dev _ num: % d' % dev_num)
Return dev_num
Dev_state.close ()

Def change_state (state_value, dev_num ):
Print ('State _ value = ', state_value)
State = not state_value
If state = True:
State = 1
# Else:
# State = 0
# Print ('State = ', state, str (state ))
Tem = OS. popen ("xinput set-prop % s 'device enabled' % s" % (str (dev_num), str (state )))
Tem. close ()

Def main ():
Dev_num = get_dev_num ()
State = check_touchpad_state (dev_num)
Change_state (state, dev_num)


If _ name _ = '_ main __':
Main ()

Source code explanation:

Popen to obtain linux Command output:

Xinput list-props

Judge the touchpad status based on the output, and change 1 to 0 and 1 to 1.

Shortcut Key definition:

Chmod + x adds executable permissions to your python script, ln-s performs soft link to/usr/local/bin, and then:
