Title:
  Ubuntu swap size default too small causes system freezes

Status in linux-hwe-6.8 package in Ubuntu:
  Invalid
Status in ubiquity package in Ubuntu:
  New

Bug description:
  On Ubuntu installations, the default swap space is set too small for
  many real-world usage scenarios. This often results in the system
  running out of swap quickly during high memory usage, which causes
  system freezes or crashes.

  Expected behavior:

  Ubuntu should configure a more appropriate swap size by default, based
  on the available RAM and usage patterns.

  The system should provide warnings or notifications when the swap
  space is almost full to prevent sudden system freezing.

  Actual behavior:

  Swap is created with a small default size (often just a few hundred MB
  or 1-2 GB), which is insufficient in many cases.

  There are no warnings or notifications when swap is close to full,
  which leads to unexpected system freezes or hangs.

  Steps to reproduce:

  Install Ubuntu with default settings.

  Use applications or workflows that consume a large amount of RAM
  (heavy browsers, virtual machines, development tools, etc.).

  Observe that the system uses up the swap quickly and eventually
  freezes or crashes without any prior warning.
