ubuntu18.04.4如何设置开机自动启动屏幕墙纸更换,步骤如下:
首先用python3 编写一个.sh 程序文件,程序文件的路径设为/xxx/change_wallpaper.sh
#!/bin/bash export DISPLAY=:0 export XAUTHORITY=/home/username/.Xauthority # change username with your user name export XDG_RUNTIME_DIR=/run/user/1000 dir=xxx # your wallpaper directory pcmanfm -w "$(find $dir -type f | shuf -n1)" # random select a picture and set it as desktop wallpaper
然后在终端输入命令行,按照自己的设置方式,比如开机自启动后每隔30分钟更换屏幕墙纸.
crontab -e # NOTE:There is a blank space after the "crontab"
在最后一行添加
*/30 * * * * /xxx/change_wallpaper.sh
reboot测试.
