I'm hoping you can help. I am a noob linux user. I installed elementary OS 5.1 on my laptop, originally I had an issue with updating apps and with turning the laptop off. App updates are now sorted, however when I turn off the laptop, it goes to a black screen with elementary logo. I have to hold the power button down at this point to turn it off. I am using a HP envy x360 laptop if that helps at all.
