Thanks for working on this! A few suggestions below, mostly for clearness.

Do you have a test job we can use for testing?

Do you have a test job we can use for testing?

The example code is

#!/usr/bin/env python3

from collections import namedtuple
from typing import List
from fractions import Fraction
from checkbox_support.monitor_config import MonitorConfig
from checkbox_support.helpers import display_info
import subprocess
import time

Mode = namedtuple("Mode", ["id", "resolution", "is_preferred", "is_current"])

def resolution_filter(modes: List[Mode]):
    new_modes = []
    tmp_resolution = []
    sort_modes = sorted(
        modes, key=lambda m: int(m.resolution.split("x")[0]), reverse=True
    )
    for m in sort_modes:
        width, height = [int(x) for x in m.resolution.split("x")]
        aspect = Fraction(width, height)
        if width < 675 or width / aspect < 530:
            continue
        if m.resolution in tmp_resolution:
            continue
        if len(new_modes) >= 5:
            break
        new_modes.append(m)
        tmp_resolution.append(m.resolution)
    return new_modes

def action(filename, **kwargs):
    print(filename)
    time.sleep(5)
    subprocess.check_output(["sudo", "keyboard_mouse"])
    subprocess.check_output(["gnome-screenshot", "-f", filename])

def cycle_test():
    try:
        monitor_config = display_info.get_monitor_config()
    except ValueError as exc:
        raise SystemExit("Current host is not support")

    monitor_config.cycle(res=False, resolution_filter=None, transform=True, action=action)

if __name__ == "__main__":
    cycle_test()

the source code of keyboard_mouse command is in #1582
