解决Manjaro i3社区版 compton默认配置不正确的问题

2020年1月10日 更新。默认配置可以使用透明，需要取消 compton.conf 中 

#inactive-opacity = 0.93;
#active-opacity = 1;
#取消这两行的注释

此问题默认存在于manjaro-i3-18.1.5-191229-linux54之前的版本中。

i3 社区版中compton包名已经改名为picom。

终端中运行：

pkill comton #关闭compton

compton -b #运行compton

错误显示为：

将.i3/config中的compton 替换为picom

删除原有.config/compton.conf

新建picom.conf文件
