如何将窗口移动到特定显示器（Ubuntu 20.04）？

如何使用代码将窗口移动到特定显示器？我有两个屏幕，一个需要全屏运行应用程序，另一个需要全屏播放视频。

答案1

您可以使用工具来实现你想要的。

我认为没有任何设置可以移动到一个屏幕或另一个屏幕，您只需要设置每个窗口的位置（x 和 y 位置）和几何形状（大小）。例如，在终端窗口中运行以下命令

xdotool search --name "WINDOW TITLE HERE" getwindowgeometry

然后在不同的显示器之间移动窗口，您将看到它只是一个不同的（左上角）x/y 位置，具体取决于您的显示器设置和分辨率。

因此，您可以进行实验并编写脚本来获取相关的窗口 ID，然后使用命令设置位置windowmove并使用命令设置几何windowsize。

答案2

我创建这python 脚本读取配置 json 文件并将每个窗口放置到所需位置。

sudo apt install xdotool
git clone [email protected]:cix-code/win-pos.git
cd win-pos
cp sample.config.json config.json
nano config.json

# Run it this way or set it as delayed startup script
python3 winpos.py

配置示例：

// Postitions the Spotify window on the second screen from the left, 
// on the second desktop centerly aligned.
{
    "name": "Spotify",
    "search_name": "^Spotify$",
    "screen": 1,
    "desktop": 1,
    "width": "50%",
    "height": "60%",
    "align": "center center"
},

该脚本只是运行相关的xrandr、xdotool和pgrep命令来检索屏幕布局、获取窗口 ID 并将窗口放置到所需的位置。

我创建了这个相当复杂的代码来找到我想要移动到特定屏幕的窗口，该屏幕由显示器的宽度（毫米）决定（它还将调整为正确的分辨率并将应用程序设置为全屏）：

#!/usr/bin/env python3
import subprocess
import time


def get(cmd): return subprocess.check_output(cmd).decode('utf-8')


def adjust_resolution(name, res):  # name = DP-2, res: 1920x1080
    get(['xrandr', '--output', name, '--mode', res])


def edit_window(monitor, window_name, function):
    print('moving', window_name, 'to', monitor)
    get(['wmctrl', '-F', '-r', window_name, '-e', '100,' +
        monitor['x'] + ',' + monitor['y'] + ',600,600'])
    get(['wmctrl', '-F', '-r', window_name, '-b', function])


def get_monitors():
    screendata = [l.split() for l in get(['xrandr', '--current']
                                         ).replace('primary', '').splitlines() if ' connected' in l]
    monitors = []

    for i in range(len(screendata)):
        monitor = dict()
        [size, x, y] = screendata[i][2].split('+')
        monitor = {
            'name': screendata[i][0],
            'width': screendata[i][-3],
            'height': screendata[i][-1],
            'size': size,
            'x': x,
            'y': y
        }
        monitors.append(monitor)

    return monitors


def find_element_where(elements, key, value):
    return next((item for item in elements if item[key] == value), None)


def window_info_to_dict(info):
    _, _, x, y, width, height, _, *name = info.split()
    return {'x': x, 'y': y, 'width': width, 'height': height, 'name': ' '.join(name)}


def get_window_info():
    return list(map(window_info_to_dict, get(['wmctrl', '-l', '-G']).splitlines()))

        secondary_monitor = next(
            (monitor for monitor in monitors if monitor['width'] != main_monitor_width), None)

        # print(main_monitor)
        # print(secondary_monitor)

        # Get windows:
        window_info = get_window_info()

        controller_app_window_info = find_element_where(

        video_player_window_info = find_element_where(

        # print(controller_app_window_info)

        if main_monitor:

                print('Controller app is not positioned correctly')
                edit_window(main_monitor, controller_app, 'add,fullscreen')
        else:

                print('Video player is not positioned correctly')
                edit_window(secondary_monitor, video_player, 'add,fullscreen')
                did_remove_fullscreen = False
        else:
            print('No secondary monitor')
            if main_monitor and not did_remove_fullscreen:
                edit_window(main_monitor, video_player, 'remove,fullscreen')
                did_remove_fullscreen = True

    except Exception as e:
        print('An error occured', e)

    time.sleep(10)
