[xubuntu-users] hibernation in Xubuntu 17.04

Sun Jul 2 00:08:55 UTC 2017

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.

Best,
Mike
