WizardConky

One of my favourite Conky desktops. I run this on Manjaro but should work with any Linux desktop providing it supports the Conky package.

Install

Depending on what OS you are running...

RedHat based systems:
yum install conky

Debian based systems:
apt-get install conky-all

Arch based systems:
pacman -Sy --noconfirm conky

...you can figure out the rest.

Create the Conky config directory:
mkdir -p ~/.config/conky

Create an emppty Conky config file:
touch ~/.config/conky/conky.conkyrc

and paste the contents from my conky.conkyrc file.

Create a a script to run Conky at boot:
echo -e '#!/bin/bash \n sleep 10 && conky -d -c ~/.config/conky/conky.conkyrc &' >> conky_start.sh

It's up to you to figure out how to trigger the conky_start.sh script at boot. This is dependent on your OS and/or desktop environment.

Upload your own icon to ~/.config/conky/icon.png
Play with the --WINDOW & BORDERS SETTINGS to make it work with your graphics card, and screen resolution
Update the font size if it is too small or large on your system
Add your own storage volumes and mount points under the Storage section. List them running df at the terminal.
Use your own Wi-Fi and Wired NIC names. Replace all instances of wlp58s0 (Wi-Fi) and enp0s20f0u1 (Wired). Find them by running ip link show athe the terminal.

Use the execi <frequency_in_sec> nmcli <shell_command> to output native linux commands to the desktop.
Have fun!
