[Bug 1699336] Re: Ubiquity in 17.04 creates a swap file that's too small for hibernation

[necwerk]

It is very sad that this hibernation issue still hasn’t been resolved,
and someone has unilaterally decided that this is an unnecessary
feature. No, it is not. This is something that Windows has been capable
of for more than 20 years, and I believe it is one of the important
features whose absence will deter users from choosing Linux.

I want to emphasize that my goal is to make Linux better and more user-
friendly, not to offend anyone.

I would like someone from Canonical to take this issue more seriously
and coordinate with the Linux kernel developers to find a hibernation
solution that is independent of the swap file. It is easy to see that
there may be cases where, with swap enabled, memory usage exceeds RAM,
making hibernation to swap impossible.

A short-term solution could be to adjust the swap file size to match the
RAM size at system startup to ensure that hibernation is more likely to
work, or perhaps a workaround that enables swap before hibernation if
swap is disabled.

Title:
  Ubiquity in 17.04 creates a swap file that's too small for hibernation

Status in ubiquity package in Ubuntu:
  Invalid

Bug description:
  In 17.04, when you use the Ubiquity installer and choose the default
  installation choice (wipe the whole disk to install), you get a swap
  file instead of an old-style swap partition. I've installed Ubuntu and
  Kubuntu 17.04 on several machines, and all of them have wound up with
  swap files smaller than their physical RAM sizes, preventing
  hibernation.

  When choosing swpa file size, Ubiquity should match the side of the
  phsyical RAM and then enable hibernation--just like it used to do.
