My Conky configuration file
Default_color let's you change the color.
If you want to change the position of your conky window, you can do that at "gap_x" and "gap_y".
minimum_size and maximum_width can change the size of your conky window.
Change the CPU parameters to your needs; e.g. if you have just two cores, remove CPU2 and CPU3.
Finally remember to change wlan0 to your network interface. Probably eth0, if wlan0 doesn't work.
