pynput and GlobalHotKeys not receiving any keyboard events

Question

This code works on Windows 10 but not on Linux. Linux does not seem to receive any keyboard events at all. When interrupting the program on Linux with Ctrl-C, this is the stack trace:

  File "/home/andreas/src/magnetfeld-aux/keyboard_events.py", line 22, in <module>
    key = kbd_q.get()
  File "/usr/lib/python3.9/queue.py", line 171, in get
    self.not_empty.wait()
  File "/usr/lib/python3.9/threading.py", line 312, in wait
    waiter.acquire()
KeyboardInterrupt

Here is the code:

from pynput import keyboard
from queue import Queue

kbd_q = Queue(maxsize=1)

def on_activate_s(): 
    kbd_q.put("Hotkey s")


listener = keyboard.GlobalHotKeys({
    's': on_activate_s,
})
listener.start()

while True:
    key = kbd_q.get()
    if key:
        print(key)

How do I get this to run on Linux?
