[Bug 1038248] Re: Ubiquity Should Check for required RAM before running, Provide helpful error

[Dmitrijs Ledkovs]

I wonder if we can do some tricks to reduce memory consumption during
installation, e.g. disable slideshow, if it turns out memory hungry,
etc.

Title:
  Ubiquity Should Check for required RAM before running, Provide helpful
  error

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  Ubiquity doesn't fail gracefully on older computers with low RAM.
  PC's with 512 MB have problems with ubiquity's manual partitioner, or
  when Ubiquity is run on a system without a swap partition.  Ubiquity
  should also check that the PC has enough RAM to install when running
  on the LiveCD, which mounts 200-300MB of files into unrecoverable RAM.

  Fedora's anaconda graphical installer has a feature that prevents out-
  of-memory crashes from occuring, by having a configurable memory
  limit.

  Having a descriptive error for this common condition would mean that
  users trying Ubuntu for the first time would not be lost.
