各位高手：

弄好了conky后，发现开机自动运行（在启动管理器里面设置）时天气不能自动更新，但是指令sudo运行就可以自动更新天气。判断应该是自动启动权限导致。

研究了几小时rc.local、rcX.d均不能成功在开机时启动conky，求教各位高手！

菜鸟一枚，请不吝赐教！

你应该去检查获取天气相关代码涉及到的文件/目录的权限，而不是想着让conky以root权限运行

感谢楼上解答，天气更新代码我看了一下是写在.conkyrc里面的，没有涉及其它文件or脚本，而且同在.conkyrc里面的其它模块正常（网速、资源占用等），就只有天气要sudo之后才更新。。。请指教，感谢！

你这个配置里获取天气的核心代码就是这一句
curl -s "http://weather.yahooapis.com/forecastrss?w=2161838&u=c" -o ~/.cache/weather.xml
你可以先用普通用户执行一下，看看能否成功执行
我觉得最大的可能是~/.cache/weather.xml这个文件的权限有问题，导致你当前用户无法写入

根据astolia大神的指点，我找到了原因，果然weather.xml是2个root而且other没有w权限，更改权限后解决了。

非常感谢astolia

PS：遇上问题先自己研究，就算失败了也了解了一些相关的知识（比如rc.local、rcX.d等等），确实没办法了就论坛搜索、发贴请教高手。。。
当然，自己学到的知识也要帮助别人！
