CAUTION: USE XINPUT TO FIND YOUR DEVICE'S IDS

README

Use "xinput" to find your device's ids

My output looks like this

Virtual core pointer                    	id=2	[master pointer  (3)]
   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
   ↳ ELAN1200:00 04F3:301A Touchpad          	id=10	[slave  pointer  (2)]
   ↳ FTSC1000:00 2808:5112                   	id=11	[slave  pointer  (2)]
Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]

  I added "python3 convertible.py" to my startup programs to have it run when I log in. Rebooting will enable your trackpad and keyboard again.
