I'm annoyed by the 'lock screen' wallpaper of KALI SANA 2.0. This is the default 'lock screen' wallpaper:
I have seen many tutorials on how to change the 'login screen' wallpaper/background but didn't find any about changing the 'lock screen' wallpaper/background picture.
Is there anyone that can guide me through the process of changing the 'lock screen' wallpaper in KALI Sana 2.0?
