I installed it ( sudo apt-get install conky) and searched on Ubuntuforums to see what other people have done.
I made my own .conkyrc file based on the ones in the thread.
* Note: If you are running 7.04 or below you will need to manually add the no flicker fix to keep conky from disappearing when it updates.
Sudo gedit /etc/X11/xorg.conf
> Under section "module" Add > Load "dbe"
To finish up this install if you would like conky to start when Gnome starts you will have to add it to the start up list.
Goto System >Preferrences>Sessions then add the custom command "conky" then you are done. to restart X Crtl+Alt+Backspace.
