Comment 20 for bug 868400

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*"
