I found another way to disable/enable touchpad from commandline:
gsettings set org.gnome.settings-daemon.peripherals.touchpad touchpad-enabled
false
gsettings set org.gnome.settings-daemon.peripherals.touchpad touchpad-enabled
true
This is working. But after touchpad breaks with hardware-button this will not
bring it back.
*
After playing with gnome-settings-daemon (gsd):
gsd-media-keys-manager is handling three different touchpadkey-events:
{ TOUCHPAD_KEY, NULL, "XF86TouchpadToggle" },
{ TOUCHPAD_ON_KEY, NULL, "XF86TouchpadOn" },
{ TOUCHPAD_OFF_KEY, NULL, "XF86TouchpadOff" },
Where first (TOUCHPAD_KEY) is only which is really doing something about
settings, two latters are only about showing info on screen. And this laptop is
only sending these ON/OFF events.
I then commented out everything relating touchpad -> Bug still triggers:
Hardware-button disables touchpad, but doesn't enable it back (this time there
are no visual icon on screen).
*
What another process/application is handling media keys? (acpi_listen is
not showing it)
