Has anyone managed to make natural scrolling work on Ubuntu 12.10? And with make work I mean to find a setup working for all the applications and not something based on Xmodmap which seems to be considered more an hack than a clean solution and in addition it doesn't enable natural scrolling on Nautilus.

I am asking that because the workaround I found to enable it with Magic Trackpads (i.e. tweak the setting Synaptic Scrolling Distance using xinput) doesn't work with Magic Mouses because such devices seem not to make use of the synaptic driver. Can you confirm that?

The following is the output of the command: xinput list-props 'Apple Magic Mouse'
