Desktop Control (Linux)

Safe desktop automation for Linux using PyAutoGUI with explicit approvals and environment checks.

Requirements

• Linux with GUI session (X11 recommended)
• Python packages:

- pyautogui - pillow - pygetwindow (window ops; not supported on Linux) - pyperclip (clipboard ops) - opencv-python (optional, image match)

System packages (common):

• python3-tk, scrot, xclip or xsel
• wmctrl (window list/activate)
• xdotool (active window)

Quick Start

python - <<'PY'
from skills.desktop_control_linux import DesktopControllerLinux

dc = DesktopControllerLinux(require_approval=True)
print(dc.get_screen_size())
PY

Screenshot to file

python - <<'PY'
from skills.desktop_control_linux import DesktopControllerLinux

dc = DesktopControllerLinux(require_approval=False)
print(dc.screenshot_to('/tmp/screen.png'))
PY

Record screen (ffmpeg)

python - <<'PY'
from skills.desktop_control_linux import DesktopControllerLinux

dc = DesktopControllerLinux(require_approval=False)
print(dc.record_screen('/tmp/record.mp4', seconds=30))
PY

Launch Chrome + open URL (default wait 15s; use 15–30s for heavy apps)

python - <<'PY'
from skills.desktop_control_linux import DesktopControllerLinux

  {"action": "open_url", "url": "http://localhost:8000/target", "wait": 15},
  {"action": "screenshot", "path": "/tmp/target.png"}
]

OCR & State Detection example

python - <<'PY'
from skills.desktop_control_linux import DesktopControllerLinux

dc = DesktopControllerLinux(require_approval=False)

# Read text from screen
text = dc.read_text_on_screen()
print(text)

if dc.wait_for_text("Success", timeout=30):
    print("Text detected!")
PY

Multi-monitor example

python - <<'PY'
from skills.desktop_control_linux import DesktopControllerLinux

dc = DesktopControllerLinux(require_approval=False)

# Get all monitors
monitors = dc.get_monitors()
print(monitors)  # [{'name': 'HDMI-1', 'x': 0, 'y': 0, 'width': 1920, 'height': 1080}, ...]

# Click on second monitor (relative 0.5, 0.5 = center)
dc.click_monitor(1, 0.5, 0.5)
PY

Multi-browser example

python - <<'PY'
from skills.desktop_control_linux import DesktopControllerLinux

dc = DesktopControllerLinux(require_approval=False)

# Open different browsers
dc.open_firefox('https://google.com', wait_seconds=15)
dc.open_edge('https://github.com', wait_seconds=15)
PY

Window Manager example

python - <<'PY'
from skills.desktop_control_linux import DesktopControllerLinux

dc = DesktopControllerLinux(require_approval=False)

# Resize window to 800x600
dc.resize_window('Chrome', 800, 600)

# Minimize window
dc.minimize_window('Telegram')

# Maximize window
dc.maximize_window('VSCode')
PY

Flow Recorder example

python - <<'PY'
from skills.desktop_control_linux import DesktopControllerLinux

dc = DesktopControllerLinux(require_approval=False)

# Start recording
dc.start_recording()

# Do some actions (manual for now, or wrap them)
dc.click(x=100, y=200)
dc.type_text('hello')
dc.press('enter')

# Stop and replay
actions = dc.stop_recording()
print(f"Recorded {len(actions)} actions")

# Replay later
dc.replay_actions(actions, delay_multiplier=1.0)
PY

AI Vision & Smart Wait example

python - <<'PY'
from skills.desktop_control_linux import DesktopControllerLinux

dc = DesktopControllerLinux(require_approval=False)

# Find element by color (RGB)
pos = dc.find_element_by_color((255, 0, 0), tolerance=20)  # red
if pos:
    dc.click(x=pos[0], y=pos[1])

# Smart wait - poll until condition is true
dc.smart_wait(lambda: dc.active_window_contains('Done'), timeout=30)

python - <<'PY'
from skills.desktop_control_linux import DesktopControllerLinux

dc = DesktopControllerLinux(require_approval=False)

# Drag from point A to B
dc.drag_drop(100, 200, 500, 600)

PY

Robust retry example

python - <<'PY'
from skills.desktop_control_linux import DesktopControllerLinux

dc = DesktopControllerLinux(require_approval=False)

# Click with automatic retry
dc.robust_click(100, 200)

# Type with automatic retry
dc.robust_type("Hello world")
PY

API

Same interface as DesktopController:

• mouse: move_mouse, click, drag, scroll, get_mouse_position
• keyboard: type_text, press, hotkey, wait, launch_app, open_url, open_chrome, wait_retry_window, wait_retry_new_window, smart_retry
• screen/ui: click_image, click_image_or, login_form
• state: ensure_window, active_window_contains, wait_for_text, detect_state
• recovery: recover_reload, recover_back, retry_with_recovery
• workflows: run_steps
• presets: register_preset, run_preset
• ocr: read_text_on_screen
• multi-monitor: get_monitors, click_monitor
• robust: robust_click, robust_type
• smart-wait: smart_wait, wait_for_window_stable
• drag-drop: drag_drop, drag_file_to_app
• window-manager: resize_window, minimize_window, maximize_window
• multi-browser: open_firefox, open_edge
• keyboard: detect_keyboard_layout
• ai-vision: find_element_by_color, find_button_vision
• recorder: start_recording, record_action, stop_recording, replay_actions

launch_app(app_name, wait_seconds=15, window_title=None, auto_detect_window=True)

• If window_title is provided: waits 15s, retries once, then errors if not found.
• If auto_detect_window=True: detects a new window title automatically, waits 15s, retries once.

smart_retry(action_fn, check_fn, wait_seconds=15, retries=2)

• Runs action → wait → check → retry (with wait) to avoid rapid loops.
• screen: screenshot, screenshot_to, record_screen, get_pixel_color, find_on_screen
• windows: get_all_windows, activate_window, focus_window_or_click, get_active_window
• clipboard: copy_to_clipboard, get_from_clipboard

Safety

• Approval mode enabled by default
• Failsafe: move mouse to any corner to abort
• Environment guard: warns on Wayland or headless sessions
• Auto-detect DISPLAY: tries /tmp/.X11-unix when DISPLAY is missing
