Conky

It displays the rich system info embedded into your desktop background.

Install

sudo apt-get install conky

Temperature probes

For older Dell laptops module i8k must be loaded and Conky use ${i8k_cpu_temp} to recall CPU temperature.

sudo apt-get install i8kutils

For modern laptops lm-sensors, then use ${acpitemp}°C to display the ambient system temperature.

sudo apt-get install lm-sensors

Configuration

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

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

Conky On and Off script

This is some times annoying to enable or disable conky on your 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
