Event Handling is don't work

[TheDeaX-Lab]

from Xlib import display
from Xlib import X
import time
disp = display.Display()
root = disp.screen().root
root.change_attributes(event_mask=X.KeymapStateMask) 
while 1:
    a = disp.next_event()
    print(a)
    time.sleep(1)

This code is don't catch the event of KeymapNotify

In my case it can't catch any event :(

I do get KeymapNotify events when I focus the root window. From the man page of XKeymapEvent(3):

generated on EnterWindow and FocusIn when KeymapState selected

It can be hard to move focus to the root window depending on your desktop environment.
