Monitor mouse coordinates in real-time in Linux

Question

I need a python coding to monitor mouse coordinates in real-time in Linux. I found below coding and it works well, but the mouse coordinates information will be shown in a pops up GUI window. Now I don't need it show in a GUI window, just need save the mouse coordinates information to a text file(Log file). Does anyone can help me that? Thanks! Plus, it would be great if it can save mouse coordinates information by hourly.

Answer 1

Going over the code you provide. The information you want comes from def mousepos(). So with just

from Xlib import display
data = display.Display().screen().root.query_pointer()._data
data["root_x"], data["root_y"]

You get the current mouse position, put this in a loop and write/append to a file. That should do the trick.
