gnome-disk-utilty does not allow swapoff of zram devices

[Brendan Perrine]

To reproduce boot a lubuntu desktop image like wily image downloaded from zsync http://cdimage.ubuntu.com/lubuntu/daily-live/20150524/wily-desktop-amd64.iso.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.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

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.
