I dont know why the setting is gone. It should already be saved when I input this commend on the terminal rm /usr/share/gdm/autostart/LoginWindow/gnome-appearance-properties.desktop
Is there something wrong..?? I found my gnome-setting-daemon.desktop also missing.
maybe that's why my background back to blank when i remove gnome-appearance-properties.desktop
How to solve it..?? i try to find whereis gnome-setting-daemon.desktop but i cant find it anywhere.
