I was suggested to disable using `xinput disable 4` command, but it throws an error :

X Error of failed request:  BadAccess (attempt to access private resource denied)
Major opcode of failed request:  131 (XInputExtension)
Minor opcode of failed request:  57 ()
Serial number of failed request:  20
Current serial number in output stream:  21

My answer is this: try to disable your touchpad from BIOS. The id of your tp is going to change randomly and disabling it by grepping from a shell script is really flaky.
