sudo apt install conky-all
nano ~/.conkyrc file
conky # if we want to run a specific configuration file, use conky -c CONKYRCFILE

killall conky # if you want to stop Conky

Another way to configure conky is to install http://www.teejeetech.in/p/conky-manager.html conky-manager]. See this. But it seems it does not work well with desktop wallpaper.

Tips

Conky/Tips and tricks

Lubuntu

For Lubuntu 14.04, the Conky's transparent function does not work at first. But This conkyrc works on Lubuntu desktop (mainly, tranparent function). To deal with the autostart, follow the suggestion from askubuntu.com. That is, go to ~/.config/autostart folder, create or copy+paste the file called conky.desktop with a content like

[Desktop Entry]
Type=Application
Exec=sh "/home/brb/.conky/conky-startup.sh"
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
Name[en_IN]=Conky
Name=Conky
Comment[en_IN]=
Comment=

and

brb@brb-VirtualBox:~$ cat .conky/conky-startup.sh 
conky &
exit 0
brb@brb-VirtualBox:~$ ls -l .conky/conky-startup.sh 
-rw-rw-r-- 1 brb brb 37 Aug 30 20:17 .conky/conky-startup.sh

On auto start on Lubuntu 18.04, add the path to the application to ~/.config/lxsession/Lubuntu/autostart  ; see How can I add new autostart programs in Lubuntu?
