[Bug 1767299] Re: Ubuntu 18.04 Installer creates swap partition too small

[Sean Horan]

I totally agree that a 1 GB default is terrible.

The problem is invisible to users who don't know how to deal with Linux
memory management.

The 6 GB laptop I have becomes unusable after a period of average
browsing, even with Chrome's tab suspender.  There's no warning that
people are out of memory, there's just sluggishness and even error
notifications that have internal failures.  There is no practical
indication--or remedy--to the less technically-inclined users that the
machine is out of memory.

Bug description:
  Installed Ubuntu 18.04 final release.

  The disk is 512 Gigabyte, the RAM is 8 Gigabyte. The installer just
  gave me 979 Megabyte of space. I chose LVM to have an encrypted drive.

  Here are some details:

  free -h

  Swap:          979M          0B        979M


  swapon --show
