Sure:

schleppi: ~/ > xinput list
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                id=11   [slave  pointer  (2)]

[...]

schleppi: ~/ > xinput -list-props 11
Device 'SynPS/2 Synaptics TouchPad':
        Device Enabled (152):   1
[...]

schleppi: ~/ > xinput -set-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 0
schleppi: ~/ > xinput -list-props 11
Device 'SynPS/2 Synaptics TouchPad':
        Device Enabled (152):   0
[...]

And indeed the touchpad no longer worked. But I could enable it again:

schleppi: ~/ > xinput -set-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 1
schleppi: ~/ > xinput -list-props 11
Device 'SynPS/2 Synaptics TouchPad':
        Device Enabled (152):   1

But the output of the last command also has two other lines which may be interesting:

        Synaptics Palm Detection (309): 0
        Synaptics Palm Dimensions (310):        10, 200

I have no idea, what to do with these but maybe they could help in the context of the original thread.
