I just installed Cinnamon DE on Ubuntu 13.10 alongside with Unity. But the two finger scrolling was not working in Cinnamon, even though it was working fine with Unity.
Turned out that when you have multiple Desktop Environments installed on Ubuntu, each one has it’s own settings application. The whole time i was trying to enable two finger scrolling from the “System Settings Application” of Unity.
But there is a different “System Settings Application” for Cinnamon, while the other one for Unity is still there.
This problem happens when you have Unity and Cinnamon both installed simultaneously.
The only way to find that out is to run both and figure it out from the looks and icons or by trial and error.
So to enable two finger scrolling in Cinnamon:
Open the System Settings application from the left panel of the menu while using Cinnamon, which can also be found under: Preferences>System Settings (Cinnamon)
Which will have square icons like below:
Click on Mouse and Touchpad and enable whatever you want.
By the way, the other System Settings app (for Unity) is under: Administration>System Settings (Unity):
And also the icons are different like Unity (not square icons like Cinnamon)
