In Ubuntu 13.10, I have "Natural Scrolling" enabled. It works great except in Nautilus which uses reversed (normal instead of natural) scrolling direction (for vertical scrolling, not just horizontal as in the related question on askubuntu.com).
There are many solved and hacky-solved similar bug reports out there, but I believe this issue is raised anew given that the "natural scrolling" setting is now implemented out-of-the-box.
Some earlier bug reports were closed because natural scrolling was accomplished by manually editing ~/.Xmodmap or by using xinput --set-prop $device_id "Synaptics Scrolling Distance" to negative values, but neither solution was considered "supported" as of yet.
However, the current setting is available in System Settings (and appears to work by switching the sign in the Synaptics Scrolling Distance property), but Nautilus still does not respect this property. Gedit, which also uses smooth scrolling, does respect the natural scrolling property.
Is this a bug that should be / is reported somewhere for Ubuntu 13(.10)? Is there a solution or a workaround that anyone is aware of?
