[Bug 1516397] Re: zram-config 01 and 0.5 load module zram in live even when there is more than 512MB

[Lenin]

I even use zram-config on machines with 8 GB RAM (or more), and if you
run software requiring memory, it's just fine. Is the problem you
encounter still true for Ubuntu 18.04 or later?

Title:
  zram-config 01 and 0.5 load module zram in live even when there is
  more than 512MB

Status in zram-config package in Ubuntu:
  Invalid

Bug description:
  Lubuntu makes use of zram-config in the Live desktop, which brought me
  to notice zram is loaded even if the machine has more than 512MB.

  There is a hook in the /usr/share/initramfs-tools/hoos directory, a
  compcache script, in which some lines say that zram must not be loaded
  if a computer has more than 512MB ram.

  This part is ignored by the system, as I could notice.

  Here is my experience about that :
  * zram-config is a good thing to have for machines up to *2GB* RAM;
  * in a machine having 3GB RAM and above, the desktop freezes and there is nothing I can do about it excepte reboot;

  My recent experience was an attempt to install in a laptop T60 32bits
  proc with 3 GB RAM, the partition was prepared before, and the machine
  had since been shutdown and rebooted later, so I was starting fresh
  (no extra processes than the ones at the start of the live), and after
  a few windows when I was at the "choose your keyboard" stage, the gui
  just froze.

  I have noticed many times since several editions that using zram-
  config in computers having more than 2GB RAM was likely to get the
  desktop to freeze : sometimes the GPU was nVidia, sometimes Intel, so
  it seems the GPU does not make a difference, but the amount of RAM
  does make a difference.

  Here are two sreenshots of the Lubuntu machines running in Virtualbox
  with 1536MB RAM. The first one is Wily 15.10 i386 with zram-config
  0.1, the second screenshot is Lubuntu Trusty 14.04.3 x86_64 in the
  same Virtualbox, 1536MB RAM.

  The consoles show the result with zram being loaded.
