前言
上周電腦重裝，換了ubuntu 16.04，想起來(lái)之前上課老師也是ubuntu而且他還提到他桌面是他自己寫的個(gè)小腳本實(shí)現(xiàn)的自動(dòng)更換桌面壁紙的，昨天晚上心血來(lái)潮自己網(wǎng)上搜了點(diǎn)資料實(shí)現(xiàn)了一下 = =
功能
功能的話，是從必應(yīng)壁紙爬取最新的那張壁紙，然后本來(lái)因?yàn)槲遗码娔X又放了太多東西，就設(shè)置了個(gè)圖片最大的數(shù)目，到達(dá)這個(gè)閾值就刪除所有的圖片= =|| 通過(guò)python的os模塊，設(shè)置壁紙，
這里可以參考：how-to-change-desktop-background-from-command-line-in-unity , 還有就是考慮到剛開機(jī)時(shí)我不一定連得上網(wǎng)（辛酸 T_T)，所以設(shè)置了一個(gè)爬取的間隔

開機(jī)自啟動(dòng)
在/home/hzy/.config/autostart中，新建一個(gè)xxx.desktop的文件，內(nèi)容如下：

說(shuō)明：
1. Exec 后面的路徑就是該腳本的路徑
2. Icon的話可以自己隨便找個(gè)圖片，設(shè)置成該路徑即可
以上這篇ubuntu 16.04LTS 開機(jī)啟動(dòng)自動(dòng)更換壁紙的實(shí)現(xiàn)方法就是小編分享給大家的全部?jī)?nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持服務(wù)器之家。
