I recently installed elementaryOS on Lenovo B50-45 laptop, the arrow of the SynPS/2 Synaptic touchpad moves on its own and the touchpad seems to be used by two people at once. No it's not a ghost 😂. Hope someone can help me 😭 thanks.

Tried to edit xinput properties
Tried to update and upgrade softwares and system
