笔记本：Thinkpad R400
显卡：ATI 3400
问题：安装完conky后，显示CPU温度等信息正常，但显示不了风扇的转速和显卡的温度，网上找了一些解决的办法，悲剧的是我运行aticonfig --adgt命令时报错。无法获取显卡温度，风扇转速的问题也没有找到解决的办法，琢磨了一下午，终于找到了解决的办法。
获取显卡温度时报错如下：ERROR - Get temperature failed for the Default Adapter - ATI Mobility Radeon HD 3400 Series
我们知道，conky获取系统信息时是通过获取系统文件的一些特殊字段来获取信息的，换句话说，conky是一个平台，我们要做的就是把所要监控的信息接入这个平台，而调取这些信息都是通过系统本身的命令来完成的，这时就显示了conky强大的功能了，几乎可以显示你想显示的所有系统信息，当然，前提是你知道如何调用这些信息，在编辑conky配置文件时，你需要对管道等linux下的概念很熟悉，同时，对grep，cut等命令的用法很熟悉，这点是非常重要的。
网上很多针对获取A卡温度的方法是调用显卡驱动本身的aticonfig --odgt命令来完成的，这确实是最好的办法，但在这种办法失效的情况下，就只有另寻别的办法了，以下是我的配置文件，我是通过sensors这个监控程序，来获取显卡的温度和风扇的转速，然后conky通过调取sensors所获得的信息的相关字段来获得风扇的转速和显卡的温度，以下是我的conky配置文件。有一点需要说明的是该配置文件参考借鉴了http://forum.ubuntu.org.cn/viewtopic.php?t=271567上的一篇文章，显示风扇转速和显卡温度是我自己加进去的，同时修改了显示器亮度的配置。在此对作者表示感谢。
