I have just installed Ubuntu 16.04 and tried to enable palm detection by doing xinput set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Palm Dimensions" 5 5 xinput set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Palm Detection" 1

But it seems it is not working. How could I make palm detection work?

You need to enable the detection first then set the dimensions. Just reverse your commands.

xinput set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Palm Detection" 1
xinput set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Palm Dimensions" 5 5
