Bug Description

To reproduce boot a lubuntu desktop image like wily image downloaded from zsync

Then boot into the live session and select try lubuntu without installing and from the main menu open acessories gnome disks. Click on the /dev/zram devices which are create equal to` nproc ` will show up but if I boot this live session on a mchaine that has swap partitions I get a stop button to perform swapoff of the device.
 swapon --summary outputs.

Description: Ubuntu Wily Werewolf (development branch)
Release: 15.10

I expected the zram compressed ram device to be able to have the swap turned off in gnome-disks through the GUI. INstead I got options to format and benchamrk the zram device which don't work and nothing to swapoff the device.

This is expected behaviour within Lubuntu where the RAM overhead is quite large compared to what lubuntu itself needs to run. Where this not used, the minimal RAM for running a Live instance would be greater than we currently state as required.
