Could not resolve keysym XF86TouchpadOn

Binary package hint: xorg

Noticed these errors in my .xsession-errors

Internal error: Could not resolve keysym XF86TouchpadOn
Internal error: Could not resolve keysym XF86TouchpadOff
Unable to find a synaptics device.

Wondering if this is the gestures stuff?

This is a desktop system without any touchpad device at all, so the errors are completely spurrious and it's probably not relevant to print them out.

Need to identify what client produces these error messages and make it suppress the prints.
