The button under settings unfortunately will be reverted as soon as I reboot. Why is there no button to disable the touchpad permamently?
Why not creating the one yourself? There some workaround.
StartUp Applicationson dash search and start it up
- Click 'Add' button, this will show you a dialog
Copy paste the following command to Command textbox :
/usr/bin/gsettings set org.gnome.settings-daemon.peripherals.touchpad touchpad-enabled 'false'
Add Name and Comment as you like
- Click 'Ok' button
Or, you can bind the following toggle script with keyboard in the setting
- Go to [System Settings] => [Keyboard] => [Shortcut] => [Custom Shortcut] => [+].
- Fill Name as you like
Fill the command something like the following
state=`/usr/bin/gsettings get org.gnome.settings-daemon.peripherals.touchpad touchpad-enabled`; if [ "$state" == "true" ]; then /usr/bin/gsettings set org.gnome.settings-daemon.peripherals.touchpad touchpad-enabled 'false'; else /usr/bin/gsettings set org.gnome.settings-daemon.peripherals.touchpad touchpad-enabled 'true'; fi
- Customize the shortcut.
Try installing the touchpad-indicator applet utility which will place a indicator icon of which you can quickly disable/enable the touchpad with and see if that works and sticks during a reboot. You will need to add this ppa, here are the install details.
Open up Terminal and issue:
sudo add-apt-repository ppa:atareao/atareao sudo apt-get update sudo apt-get install touchpad-indicator
FYI - I don't have this issue and can't reproduce it using a Lenovo Thinkpad with 14.04 Unity (Stock install). So if touchpad-indicator doesn't work either, then you may have something else going on.
