I found a workaround to invert the two finger scrolling behavior. It is enough to add a file .Xmodmap in the home dir with the following content:
$ cat .Xmodmap pointer = 1 2 3 5 4 6 7 8 9 10 (note that the forth and fifth numbers are swapped) This invert the two finger scrolling direction, but unfortunately also the direction of scrolling of the wheel of an external mouse, if used... Anyway, for those using only the touchpad I think it is a good, temporary compromise :) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1590590 Title: Touchpad not recognized on Dell Latitude E7470 Ultrabook Status in linux package in Ubuntu: Triaged Status in xserver-xorg-input-synaptics package in Ubuntu: Confirmed Bug description: Expected: Touchpad settings available in Mouse & Touchpad Settings dialog Actual result: Touchpad settings missing entirely Details: The touchpad on my Dell Ultrabook (Latitude E7470) functions mostly. The settings for the touchpad are not available at all in the Mouse and Touchpad settings (see http://i.imgur.com/YRGiOrj.png).
