[gigipin <868400@xxxxxxxxxxxxxxxxxx>]

I have a solution that i've tested before.

My problem was that the touchpad didn't work on start up, but only on
log in. In the Xorg's log the SynPS/2 was recognised, but i suppose
there may be a link problem with the driver, so i've adjusted the xorg
configuration.

I've created a new empty /etc/X11/xorg.conf file and set the following
rules in it:

Section "InputClass"
        Identifier      "Touchpad"                      # required
        MatchIsTouchpad "yes"                           # required
        Driver          "synaptics"                     # required
        Option          "MinSpeed"              "0.5"
        Option          "MaxSpeed"              "1.0"
        Option          "AccelFactor"           "0.075"
        Option          "TapButton1"            "1"
        Option          "TapButton2"            "2"     # multitouch
        Option          "TapButton3"            "3"     # multitouch
        Option          "VertTwoFingerScroll"   "1"     # multitouch
        Option          "HorizTwoFingerScroll"  "1"     # multitouch
        Option          "VertEdgeScroll"        "1"
        Option          "CoastingSpeed"         "8"
        Option          "CornerCoasting"        "1"
        Option          "CircularScrolling"     "1"
        Option          "CircScrollTrigger"     "7"
        Option          "EdgeMotionUseAlways"   "1"
        Option          "LBCornerButton"        "8"     # browser "back" btn
        Option          "RBCornerButton"        "9"     # browser "forward" btn
EndSection

This is working perfectly for me, is not necessary set all commands like
me only the required ones, perhaps the cause is a command line, in
/usr/share/X11/xorg.conf.d/50-synaptics.conf, wrong and may be this:

MatchDevicePath "/dev/input/event*"
