I have reinstalled my system, a Samsung Series 9 laptop with a clickpad, under Ubuntu 12.04. I reinstalled it a few times and re-configured it with the same OS because I had issues with the filesystem getting corrupted (ext4 on this SSD with this kernel isn't so great apparently).

Anyway, I re-installed it for a Nth time and configured the ClickPad the same way as before:

/usr/share/X11/xorg.conf.d/52-clickpad.conf

Section "InputClass"

        Identifier      "np900x3b clickpad"

        MatchIsTouchpad "on"

        MatchDevicePath "/dev/input/event*"

        Option          "ClickPad"      "1"

        Option          "ClickFinger1"  "1"

        Option          "ClickFinger2"  "3"

        Option          "ClickFinger3"  "2"

        Option          "FastTaps"      "1"

        Option          "RightButtonAreaLeft"   "2000"

        Option          "RightButtonAreaTop"    "1500"

EndSection

I had the same configuration before (I actually copied it from a USB drive), and it worked fine. Yet I get this after restarting X:

$ synclient -l | grep -i "(right|click|fast)"

    RightEdge               = 2974

    ClickTime               = 100

    FastTaps                = 1

    ClickFinger1            = 1

    ClickFinger2            = 3

    ClickFinger3            = 2

    AreaRightEdge           = 0

    ClickPad                = 1

    RightButtonAreaLeft     = 0

    RightButtonAreaRight    = 0

    RightButtonAreaTop      = 0

    RightButtonAreaBottom   = 0

    MiddleButtonAreaRight   = 0

It appears that all options are being handled properly, except the RightButtonArea[...] ones. Looking at X logs gives me no clue about the problem, with no errors, only this:

[  1499.416] (--) synaptics: ETPS/2 Elantech Touchpad: Vendor 0x2 Product 0xe

[  1499.416] (**) Option "ClickPad" "1"

[  1499.416] (**) Option "FastTaps" "1"

[  1499.416] (**) Option "ClickFinger1" "1"

[  1499.416] (**) Option "ClickFinger2" "3"

[  1499.416] (**) Option "ClickFinger3" "2"

[  1499.416] (--) synaptics: ETPS/2 Elantech Touchpad: touchpad found

If I set them manually using synclient:

synclient RightButtonAreaLeft=2000

...then it works, but obviously I have to set manually them every time I start X.

Note that RightButtonAreaLeft depends on ClickPad=1 to work, although it is set correctly.

So it seems that the RightButtonArea[...] options are simply ignored by X. Like I said, I just reinstalled the system a few times before and it worked perfectly fine on every occasion.

Any help is greatly appreciated.
