全屏应用期间关闭 SUPER 键

有没有办法在玩游戏或全屏应用时关闭 SUPER 键？

答案1

介绍

如果任何 X11 窗口处于全屏模式，则以下脚本将禁用Super键。它旨在作为启动应用程序添加，但也可以以独立模式运行。

用法

要手动运行脚本，只需执行以下操作：

python disable_super_key.py

为了使脚本在登录时自动启动，请咨询如何在登录时自动启动应用程序？

获取脚本源代码

可以从此答案复制脚本源，或通过克隆我的GitHub存储库。

针对以下人士的说明git：

  1. cd /opt
  2. sudo git clone https://github.com/SergKolo/sergrep.git
  3. chmod -R +x sergrep

该脚本将位于/opt/sergrep/disable_super_key.py

调试

如果需要调试，请将第 32 行从 更改debug = False为debug = True并从命令行运行脚本
