Ubuntu regularly locks up and black screens when I try to sleep/hibernate. It's a very common problem that has nothing to do with Windows or Microsoft. I also have had 0 issues with dual booting for roughly 10 years now. HN wouldn't be HN without some baseless MS bashing.
I have had occasional issues with Windows and various flavors of Linux hibernating but nothing that happens with any regularity - at all - and nothing that can't be solved by simply rebooting.
