Conky – system info on your desktop

I am using Conky as a system info which is directly embedded into my Linux desktop background. The rich configuration options and flexibility allows various data to be displayed in fully configurable format adding extra blink to the desktop wallpaper.Conky

Install
sudo apt-get install conky
Configuration

User based config file is located in ~/.conkyrc file. The rich features that can be displayed on the background are limitless. Below is my config based on Dell Latitude D600.

# UBUNTU-CONKY
# A comprehensive conky script, configured for use on
# Ubuntu / Debian Gnome, without the need for any external scripts.
#
# Based on conky-jc and the default .conkyrc.
# INCLUDES:
# - tail of /var/log/messages
# - netstat shows number of connections from your computer and application/PID making it. Kill spyware!
# - for Dell laptops module i8k must be loaded from package: i8kutils then cpu_temp can be read using i8k_cpu_temp 
#
# ${if_existing /proc/net/route  - it checks if default GW exists, it is helpful with external IP determination
#

Conky On and Off script

It is sometime annoying to enable or disable conky on the dektop. The following scrip comes with help.

piotr@d600:~$ cat conky_on_off.sh 
#!/bin/sh

# click to start, click to stop

if pidof conky | grep [0-9] > /dev/null
then
 exec killall conky
else
 exec conky
fi
