So for a while I've wanted to switch over to Linux. I chose Ubuntu because I thought it would be really easy to transition from Windows. However, I've had a myriad of problems but the worst one is that if I close my laptop and then re-open it, sign in, after about 10 seconds the laptop just goes back to sleep. This continues until I restart my laptop. I'm new to Linux but am comfortable navigating the terminal a bit. Any help is appreciated thank you.
