I3wm
Installing i3 requires only a few lines. Theming and tweaking your Arch Linux system will require more time. All the information about this desktop is here:

https://wiki.archlinux.org/index.php/i3

Let us go over every settings of Arch Linux i3 and see what we still need to fix.

We go inside the xfce-settings-manager to set the keyboard to azerty. Then we edit the ~/.config/i3/config to launch xfsettingsd.

We change the theme, icons, cursor… with lxappearance.

We choose the wallpaper with variety.

We tell the conky in ~/.config/i3/config not to start with adding a # at the beginning of the line.

We choose a different bar : conky-i3statusbar.

Then we install trizen and polybar.

We change the settings in polybar of up and down network traffic.

We get the .bashrc from ArcoLinux to get pksyua and mirror for example.

sudo pacman -S reflector — You need to install reflector to use mirror.

Tips

To set our keyboard we may use setxbmap as well.
