So I have googled and got some solution which can fix my problem.
Open your conkyrc file which is a hidden file in home directory with
$ vim .conkyrc
$ vim ~/.conkyrc
Find the area of below lines and make the configuration as I have mentioned.
Then save and exit from your conkyrc file.
Then in we have to reload the conky with updated configuration , so all you have to do is kill the conky and then start it again.
so In your terminal as root user do as
# killall conky & conky
$ su -c ” killall conky & conky”
I hope that will help you.
