通过边缘绑定显示启动器

通过边缘绑定显示启动器

我使用 2 个显示器（其中右侧的显示器在像素和物理指标上都小于左侧的显示器），并且经常想在自动隐藏的启动器上打开右侧显示器上的某些内容。（显示设置中的粘性边缘已关闭，因此在屏幕之间移动光标感觉更自然。）这要求我将光标缓慢移动到右侧显示器的左边缘，因为如果我像平常一样快速移动它，光标会移动到左侧显示器。

我希望我可以移动光标到底部边缘来淡入启动器。但是，我找不到命令来执行此操作。

如果有命令可以让启动器淡入或以其他方式执行此操作，请告诉我。

当鼠标进入“触发”区域时显示启动器

当鼠标指针进入某个区域时，下面的脚本会激活（自动隐藏的）启动器（激活区如图所示）。

因为绘制一个完全是直线朝向目标启动器图标，启动器激活后，我在屏幕（右）左侧创建了一个 200px 的区域，您可以在其中自由移动，而无需再次隐藏启动器（移动区域）。

在此处输入图片描述

如何使用

  1. 该脚本用于xdotool获取鼠标位置：

    sudo apt-get install xdotool

  2. 将脚本复制到一个空文件中，另存为trigger_launcher.py

  3. 在脚本的头部，我设置了适合您的屏幕组合和顶部对齐的值。但是，如果您要将脚本用于其他屏幕（尺寸），或者想要更改（触发器）边距，则可以在脚本的头部进行更改：

    # the script assumes the two screens are top-alligned (!)

#-- set the area to trigger the launcher (from left bottom of second screen) below:
vert_marge = 50
hor_marge = 200
#-- set the width of the left screen below:
width_screen1 = 1680
#-- set the height of the right screen below:
height_screen2 = 900
#---

  4. 使用以下命令测试脚本：

    python3 /path/to/trigger_launcher.py

  5. 如果一切正常，请将其添加到启动应用程序：Dash > 启动应用程序 > 添加。添加命令：

    /bin/bash -c "sleep 15&&python3 /path/to/trigger_launcher.py"

vert_line = height_screen2-vert_marge
