I am running Ubuntu 12.04.2 LTS and I had thought I had permanently disabled the touch pad by
- updating system settings to reflect my preferences
- running a one time 'gsettings set org.gnome.settings-daemon.peripherals.mouse middle-button-enabled true'
- running 'xinput set-prop 12 "Device Enabled" 0' in my $HOME/.bashrc
This setup works fine, when I lock the screen and unlock it. However, after my session gets suspended because of inactivity followed by unlock of the screen, the touch pad is no longer disabled.
Attempt to launch the app touchpad-indicator(version 0.8.1.1-1ubunt) as a possible remedy crashes at startup.
Is there a better solution than, rerunning xinput set-prop 12 "Device Enabled" 0 every time I log into my session after a suspend?
