Hi i have installed ideneb v1.4 on my HP laptop (dv5-1085eo) and now when i start it everything works like a charm, but when i want to shutdown, restart or sleep the computer i starts to do that, but then it like freezes with background image and nothing happens more. I don't know why this is happening and would be thankful if someone could help me out with this
