The following change is under review. It might look different when we release it!
Recently, I’ve been working on improving the Unity 7 low graphics mode (relevant posts: http://www.omgubuntu.co.uk/2016/11/see-just-much-faster-unity-7-low-graphics-mode and https://ufuntu.wordpress.com/2016/10/18/unity-7-low-graphics-mode-improved/)
One problem I’ve faced was that there wasn’t an easy way to enable and disable the Low Graphics Mode. Besides that, there was a ccsm option named “Enable Low Graphics Mode” that only removes the blur from dash and doesn’t enable the new features, which confused most users.
To avoid such confusion and make sure that everyone uses the improved Low Graphics Mode when it’s available, we decided to remove the “Enable Low Graphics Mode” option from ccsm on desktops that support the new features. Users that have the recent versions will be able to enable and disable the low graphics mode from unity-control-center only. Others can still use ccsm, to enable the older Low Graphics Mode version.
