Bug Description

[Impact]
There's a ccsm setting that is called "Low Graphics Mode". When this setting is checked the blur is removed from the dash and the launcher in Unity 7. New Low Graphics Mode features like moving windows and others that are presented on this video: https://www.youtube.com/watch?v=cW_Bg0WrS3Q cannot be enabled through this checkbox and their settings are spreaded in different plugins. The low graphics mode setting shouldn't be a Unity plugin option but a global gsetting that is checked by u7.

[Test Case]
1. Open terminal
2. gsettings get com.canonical.Unity lowgfx
3. Returns True of False (not "No such key 'lowgfx'")

[Potential Regression]
None

I can verify that after upgrading to 1:0.9.12.3+16.04.20171116-0ubuntu1, that gsetting controls low graphics mode.

I had low graphics mode enabled before upgrading, using
~$ cat .config/upstart/lowgfx.conf
start on starting unity7
pre-start script
    initctl set-env -g UNITY_LOW_GFX_MODE=1
end script

which was how it was suggested to enable it at some point in the past. This script is still there after upgrade, but it seems people that have the script need to still set the new gsettings key to get the full benefit. (I'm not sure there's a better way, fwiw; I don't think this should block things, but I do think it's a little bit untidy).

Mh, that environment variable is still supported, and actually running unity with that set should make it use the non-3d version too.
