之前因为一直在用Ubuntu 18或者Ubuntu 20然后发现装了GNOME插件后#xff0c;电脑在使用过程中#xff0c;会时不时的卡死#xff08;鼠标没问题#xff0c;键盘输入会有10-20秒的延迟#xff09;频率基本是一小时一次#xff0c;因为这种卡顿会很容易打断思路电脑在使用过程中会时不时的卡死鼠标没问题键盘输入会有10-20秒的延迟频率基本是一小时一次因为这种卡顿会很容易打断思路所以我重装了系统从最小化安装开始什么软件都经过我一手安装了没有安装GNOME插件发现没有卡顿的现象了初步排查是GNOME插件的问题。
所以就有了这篇用脚本实现窗口平铺的文章。如何你们用插件没有这个BUG那么可以直接下载GNOME- WinTile插件就可以实现了。

创建脚本文件/usr/local/bin/ubuntu_move_windows内容如下

shift $((OPTIND-1))main $保存写入后给这个文件添加执行权限sudo chmod x /usr/local/bin/ubuntu_move_windows 。 然后来到设置中添加键盘快捷键-自定义快捷键如下 这个快捷键是按照Mac OS里的Magnet软件来设置的
