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/
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.

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?
