'Show desktop' should not minimize those windows marked as 'Always on top'.

[Wibol]

On the Linux Mint forum a user complains that the operation of 'Show desktop' in Cinnamon is different from other graphical environments. According to him, all windows should be minimized except those that have been marked by the user as 'Always on top'.

He has solved it by installing the package:

apt install xdotool

And creating a launcher for the script:

#!/bin/bash
# Este script minimiza todas las ventanas "normales" que no estén marcadas como "siempre encima"
# y que no sean las notas adhesivas (sticky notes).

for win in $(wmctrl -l | awk '{print $1}'); do
    # Filtra solo ventanas de tipo normal
    type=$(xprop -id $win _NET_WM_WINDOW_TYPE 2>/dev/null)
    if [[ "$type" == *"_NET_WM_WINDOW_TYPE_NORMAL"* ]]; then
        # Obtiene la clase de la ventana para identificar sticky notes
        wm_class=$(xprop -id $win WM_CLASS 2>/dev/null)
        # Si la clase contiene "sticky" (sin distinguir mayúsculas/minúsculas), la omite
        if echo "$wm_class" | grep -qi "sticky"; then
            continue
        fi

        # Obtiene el estado de la ventana
        state=$(xprop -id $win _NET_WM_STATE 2>/dev/null)
        # Si la ventana NO está marcada como "siempre encima", la minimiza
        if [[ "$state" != *"_NET_WM_STATE_ABOVE"* ]]; then
            xdotool windowminimize $win
        fi
    fi
done
