conky 主要的功能是在桌面上顯示系統資訊，當然也可以顯示其他有趣的資訊。先安裝吧：
$ yaourt -S conky conkywx
說明文件在這裡。
安裝後，就要設定配置檔。google 一下，滿坑滿谷的 screenshot 和 config，只要有想象力，時間，在加上一些耐性，一定可以作出符合自己需要的桌面。
預設的配置檔是放在 $HOME/.conkyrc。在 /etc/conky/conky.conf 這裡有個範例，不過，應該不會有人不改就套用吧。
我是把配置檔放在 ~/.conkyrc，方便未來備份。配置檔很長，放在本文的最後。
conkywx是用來顯示天氣狀況。至少需要兩個檔案：
- ~/.config/conkywx/conkywx.conf
- ~/.config/conkywx/template.sh
在 .conkyrc 中用下面的方法連接過去。
template0 "/usr/bin/conkywx"
template1 "/home/mario/.config/conkywx/conkywx.conf"
template2 "/home/mario/.config/conkywx/wx-wu-font-slim-template.sh"
${execpi 7200 ${template0} -c ${template1} -t ${template2}}
conkywx.conf 中設定以下 2 個參數
- use_xml=0
- Location=46696
就可以看到松山機場的天氣狀況。其他的地方如下：
