在全屏应用程序中关闭超级键

通常，是否可以在游戏会话或全屏应用程序中关闭SUPER键？

介绍

Super如果任何X11窗口处于全屏模式，则以下脚本禁用键。它打算作为启动应用程序添加，但也可以独立运行。

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，请参阅如何在登录时自动启动应用程序？

获取脚本源代码

可以从这个答案中复制脚本源，或者通过克隆我的GitHub存储库获得脚本源。

对于那些谁的说明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
