Ubuntu – Create a keyboard shortcut to move windows to a specific screen edge

Are you actually using Numpad 0-9 in those keyboard shortcuts?

This is a numpad

The row of numbers of above the QWERTY keys will not work.

In future releases of Ubuntu (like 12.04) you will be able to tile windows using Ctrl-Super-↑, Ctrl-Super-←, and Ctrl-Super-→.

Introduction

window_jumper.py is a python script that will move active window across multiple monitors in cycle. For instance, if you have 3 monitors A,B, and C , repeated keypress of the assigned shortcut will move the window from A, to B, to C, and back to A. The window placement will be Top Left corner of each screen.

Usage

To run script manually

python window_jumper.py

The script has no command line options ( as of right now , but may in future ).

Script source

Also available as on GitHub. If you have GitHub account, please submit issues and feature requests there.

#!/usr/bin/env python
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import GdkX11, Gdk, Gtk


def main():

    DEBUG = False

    screen = GdkX11.X11Screen.get_default()
    monitors = []
    for monitor in range(screen.get_n_monitors()):
        monitors.append(
            [screen.get_monitor_geometry(monitor).x,
             screen.get_monitor_geometry(monitor).y])

    if DEBUG:
        print monitors

    active_window = screen.get_active_window()
    active_window_location = screen.get_monitor_at_window(active_window)

    new_location = None
    new_location = active_window_location + 1
    if active_window_location + 1 >= monitors.__len__():
        new_location = 0
    new_screen = monitors[new_location]
    if DEBUG:
        print new_screen

    active_window.move(new_screen[0], new_screen[1])
    screen.get_active_window()
    # TODO: add resizing window routine in cases where
    # a window is larger than the size of the screen
    # to which we're moving it.

if __name__ == "__main__":
    main()
