So I recently installed Ubuntu on my computer, which was previously running only Windows 7, and whenever I boot into Ubuntu and play a YouTube video in fullscreen, it works smoothly for the first couple of minutes.
After a while, the video begins to be really laggy and my computer follows suit and everything is laggy. So, just to clarify, in Ubuntu, when I’m playing a YouTube video in fullscreen, my whole computer starts lagging, and the only way to get it to work normally again is to reboot it.
I’m wondering what possibly could cause this problem, and what I can do to fix it.
Any and all help is much appreciated.
