Displaying System Details On Your Desktop With Conky System Monitor On Ubuntu 7.04

Version 1.0
Author: Oliver Meyer <o [dot] meyer [at] projektfarm [dot] de>

This document describes how to set up the light-weight Conky system monitor on Ubuntu 7.04. Conky is a desktop widget that is able to display most diverse information like CPU temperature, current used network-bandwith or anything you want. You can customize the whole layout including colors and fonts.

This howto is meant as a practical guide; it does not cover the theoretical backgrounds. They are treated in a lot of other documents in the web.

This document comes without warranty of any kind! I want to say that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!

 

1. Install Conky

Install Conky with the Synaptic package manager:

 

2. Configuration

There are a great many configuration options and predefined variables to customize Conky that I can't list and explain all here. A good documentation, including the manpage, FAQ, a list of Conky variables and a list of Conky config file settings, is available at http://conky.sourceforge.net/.

In some cases Conky has a problem with flickering. If you have this problem on your machine you should take a look at the FAQ - there are solutions to solve this problem.

Open a terminal and create the config-file for Conky.

Use the default configutaion:

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

Or use my configuration:

vi .conkyrc

3. Menulauncher

To make Conky accessible from the Applications menu, we create a launcher. First right click on the menubar and select Edit Menus:

Select System Tools in the new pop-up on the left side:

Click on New Item on the right side to create a new launcher. Insert/select the following:

Type: Application
Name: Conky
Command: conky
Comment: insert a comment if you want.
Icon: select one if you want.

Now you can start Conky via the Applications menu:

If you chose my configuration at step 2 it should look like this:
