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. 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?
