Conky

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

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”
