Regarding my post #24, I think a better workaround, instead of changing .Xmodmap, is to add the following line to the file:
~/.xinputrc xinput set-button-map "ImPS/2 Generic Wheel Mouse" 1 2 3 5 4 6 7 in this way only the two-finger scrolling direction of the unrecognized touchpad will be inverted, while the wheel scrolling direction of an external mouse will not be modified. In addition, due to some bug in unity/gnome not all the applications interpret correctly .xinputrc/.Xmodmap commands. So for example chrome/firefox will be ok, but nautilus windows will still use the "natural" scrolling, regardless of .xinputrc/.Xmodmap content. I did not find a solution to solve these inconsistencies. The only real solution will be of course a proper support of our touchpad at kernel level -- 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.
