Conky – a light weight system monitor for Ubuntu L

转自：

Conky is an advanced, highly configurable system monitor for X based on torsmo.Conky is an powerful desktop app that posts system monitoring info onto the root window. It is hard to set up properly (has unlisted dependencies, special command line compile options, and requires a mod to xorg.conf to stop it from flickering, and the apt-get version doesnt work properly). Most people can’t get it working right, but its an AWESOME app if it can be set up right done.

Install Conky in Ubuntu

sudo apt-get install conky

This will complete the installation

Configuring Conky

Make a configuration file in your home directory (Ex:-/home/ubuntuadmin)

vi /home/ubuntuadmin/.conkyrc

Paste the following code into the file and save / exit

You can also extract the sample file using the following command

zcat /usr/share/doc/conky/examples/conkyrc.sample.gz > ~/.conkyrc

If the network connections graph does not work, you will have to change all “eth0″ references to “ppp0″ (for modem) or “ath0″ (for other devices).

Add dbe module to /etc/X11/xorg.conf to reduce flickering.

sudo vi /etc/X11/xorg.conf

find the section titled Section “Module”, and add the following line

Load “dbe”

Add conky to Startup programs

Go to System—>Preferences—>Sessions

Once it opens you should see the following screen

Now you need to select statup programs tab and click on add

Once it opens you should see the following screen here you need to click on browse

Now you need to select conky from /usr/bin and click on open

Once you click on open you should see the following screen here you need to select ok and close

Next time when you reboot your machine conky will start automatically.

If you want to start this from command line just enter the following command

conky

Output looks like below

Ubuntu如何解决conky闪烁问题

转自：http://www.boear.com/blog/archives/2008/10/121.html
在安装之后默认状态下并不会闪烁，但是经过配置之后就往往会出现闪烁的问题。解决办法如下：
sudo apt-get install wmctrl
sudo vim /etc/X11/xorg.conf
在Module段加入一行：
   Load    “dbe”
保存后退出。

设置conky的配置文件：
   vim ~/.conkyrc
设置以下几项：
own_window yes
own_window_type override
double_buffer yes
保存后退出。
