[SOLVED] Synaptics configuration stops working

Hi, after last system update, my /etc/X11/xorg.conf.d/50-synaptics.conf stoped to affect on my touchpad configuration. I copyed 50-synaptics.conf.pacnew to 50-synaptics.conf and edit it. But touchpad acts as with default configuration. What changed in new version of xorg or synaptics?
Here my synaptics configuration:

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        #Option "TapButton1" "1"
        Option "TapButton2" "2"
        #Option "TapButton3" "3"
        MatchDevicePath "/dev/input/event*"
EndSection

Section "InputClass"
        Identifier "touchpad ignore duplicates"
        MatchIsTouchpad "on"
        MatchOS "Linux"
        MatchDevicePath "/dev/input/mouse*"
        Option "Ignore" "on"
EndSection

Section "InputClass"
        Identifier "Default clickpad buttons"
        MatchDriver "synaptics"
        Option "SoftButtonAreas" "50% 0 82% 0 0 0 0 0"
        Option "SecondarySoftButtonAreas" "58% 0 0 8% 42% 58% 0 8%"
EndSection
Section "InputClass"
        Identifier "Disable clickpad buttons on Apple touchpads"
        MatchProduct "Apple|bcm5974"
        MatchDriver "synaptics"
        Option "SoftButtonAreas" "0 0 0 0 0 0 0 0"
EndSection

Re: [SOLVED] Synaptics configuration stops working

The following is my assumption based on wordings in man page.
In case of X server ALL xorg files are run through. So file in /usr/share/X11/xorg.conf.d and /etc/xorg.conf.d are parsed (even if with same name)

So in short commenting out lines will not work. (As Xorg will parse the file in /usr/share/X11/xorg.conf.d/50-synaptics.conf and take it as default)

You have to specify explicit settings in /etc/xorg.conf.d/50-synaptics.conf (i.e. do not simply comment them)
Example:
Option "TapButton1" "0"

What I have done is to be safe I created a file with /etc/X11/xorg.conf.d/51-synaptics.conf (50 replaced by 51)

And put my settings in it.

Section "InputClass"
        Identifier "touchpad catchall mine"
        Driver "synaptics"
        MatchIsTouchpad "on"
        Option "TapButton1" "0"
        Option "TapButton2" "0"
        Option "TapButton3" "2"
# This option is recommend on all Linux systems using evdev, but cannot be
# enabled by default. See the following link for details:
# http://who-t.blogspot.com/2010/11/how-to-ignore-configuration-errors.html
        MatchDevicePath "/dev/input/event*"
EndSection

Note the change in identifier name.

Also NOTE that you dont have to copy all sections, just copy sections where you have changed the default settings.
