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

[Humphrey van Polanen Petel]

I installed 16.04 on a hand-me-down laptop, because I need to support another system that is on 16.04 and it is easier for me to have an identical system
I installed 16.04, because later versions do not allow remote control using remmina (# 1790251, 1790249 & 1741027).
System is a 8Gb laptop with a 480Mb ssd.
Installer created a swap of 976Mb.
Install version was 16.04.5.  (Note that my DVD with 16.04.3 creates a swap of appropriate size.)

The system will hang when used heavily, but does recover.

However, contrary to earlier comments, rebooting during such a 'freeze'
is *not* guaranteed safe.  On my system it has multiple times corrupted
the file system which caused boot to fail and which required a run of
"fsck /dev/sda1".

After I followed instructions found on
help.ubuntu.com/community/SwapFaq, I now have an 8.3Gb swap and the
system does not hang any more.

I spent two weeks before I realized that the problem was with the swap
size.

In my opinion it is bad to change something as dramatic as swap-size.
The installer should ask questions and give options.

*** This is not an "opinion" and consequently I have re-opened it ***

  Ubuntu 18.04 Installer creates swap partition too small

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:
