A very simple and clean conky All you got to do is create a .conky folder in your home directory:
mkdir ~/.conky/
cd ~/.conky/
-- git clone the files in this directory, or move them there if you have them in a diffrent directory.
git clone https://github.com/ap-nas/xfce-simple-conky/
Then: chmod +x start.sh
./start.sh
Then set the start.sh script to autostart using the Session and startup manager.
