I suspect that using a /swapfile creates some complexities that aren't there with an ordinary swap partition. 17.04 uses /swapfile and 16.04 automatically created a swap partition of the right size. The supposed advantage of the swapfile over the swap partition is that uses less space unless needed. Is that right? I don't see how it makes sense. If I need up to 2GB for hibernation, I what that space always available to me. So for systems that might sometimes hibernate, the partition makes more sense than the swapfile. Am I understanding this correctly?
Maybe if you were to try installing 17.04 with a swap partition you'd have better luck. Anyway, 16.04 should have been my choice in the first place. It's perfect for my uses. But when I first installed Xubuntu, I was thinking of selling the laptop or giving it away. After I installed it, I realized how much I liked it and that I had a good use for it. So I'm keeping it.
