I'm trying to configure my touchpad by adding options in a the newly created file /etc/X11/xorg.conf.d/50-synaptics.conf. The file looks like this:Section InputClass        Identifier enable HorizTwoFingerScroll        MatchDriver synaptics        Option HorizTwoFingerScroll 1EndSectionhowever, this change does not seem to be accepted after a reboot. Using synclient -l reveals HorizTwoFingerScroll is still set to 0.Setting the value via synclient HorizTwoFingerScroll 1 makes it work, but after restarting the value is reset again. I already deactivated the gnome settings deamon via dconf-editor, because I thought that might be the problem, but that did not make any difference.Another strange thing is that the touchpad is not recognized by the system anyway. Using sudo evtest or xinput shows that there is an unknown device. This is the output of xinput: Virtual core pointer                      id=2    [master pointer  (3)]    Virtual core XTEST pointer                id=4    [slave  pointer  (2)]        UNKNOWN                               id=11   [slave  pointer  (2)] Virtual core keyboard                     id=3    [master keyboard (2)]     Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]     Power Button                              id=6    [slave  keyboard (3)]     Video Bus                                 id=7    [slave  keyboard (3)]     Video Bus                                 id=8    [slave  keyboard (3)]     Power Button                              id=9    [slave  keyboard (3)]     Sleep Button                              id=10   [slave  keyboard (3)]     HD WebCam                                 id=12   [slave  keyboard (3)]     AT Translated Set 2 keyboard              id=13   [slave  keyboard (3)]     Acer WMI hotkeys                          id=14   [slave  keyboard (3)]Using xinput --list-props 11 shows that this is indeed a synaptics touchpad. Output:Device '    UNKNOWN':    Device Enabled (137):   1    --- lots of Synaptics Options ---    Device Product ID (257):    1739, 10608    Device Node (258):  /dev/input/event13The only thing that works is adding synclient HorizTwoFingerScroll 1 as startup application, but thats not how I want it to be solved. And I don't want to add a startup application for every option I'd like to set. Using the file /etc/X11/xorg.conf.d/50-synaptics.conf seems like the best way.Now my question is: What do I need to do in order to make my changes in this file be accepted? My Kernel version is 4.2.0-18-generic.
