I decided that I wanted Ubuntu on my laptop, since Windows 10 and Windows 7 are just not good options for it in many ways. Anyways, when I was installing Ubuntu, the installation would constantly freeze, and I couldn't install it. I fixed this by turning on Safe Graphics, but now that it's installed, it's freezing even more often. My head is going to explode. I'm so frustrated with this. Can someone please tell me how I can prevent Ubuntu from freezing?
