Touchpad cpu to 100%

Dear felow arch users,

Since a few days I have some problems on my laptop. Using the touchpad makes my cpu going to 100% on the 4 cores.
I've reinstalled the package xf86-input-synaptics but it doesn't help.

My xorg.conf:

Section "ServerLayout"
    Identifier     "aticonfig Layout"
    Screen      0  "aticonfig-Screen[0]-0" 0 0
EndSection

Section "Module"
EndSection

Section "Monitor"
    Identifier   "aticonfig-Monitor[0]-0"
    Option        "VendorName" "ATI Proprietary Driver"
    Option        "ModelName" "Generic Autodetecting Monitor"
    Option        "DPMS" "true"
EndSection

Section "Device"
    Identifier  "aticonfig-Device[0]-0"
    Driver      "fglrx"
    BusID       "PCI:1:0:0"
EndSection

Section "Screen"
    Identifier "aticonfig-Screen[0]-0"
    Device     "aticonfig-Device[0]-0"
    Monitor    "aticonfig-Monitor[0]-0"
    DefaultDepth     24
    SubSection "Display"
        Viewport   0 0
        Depth     24
    EndSubSection
EndSection

Shouldn't be the problem because only my ati graphics card is configured in it.

My xorg.conf.d/10-synaptics

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

Which is the standard config file of it.

If anyone has a solution for this problem I'd be more than happy to hear about it.

Thank you in advance.

Sincerely yours,
n0tiz

EDIT:
In my Xorg.log i found the next lines according to my touchpad:

[   103.540] SynPS/2 Synaptics TouchPad: Read error No such device
[   103.540] (II) config/udev: removing device SynPS/2 Synaptics TouchPad
[   107.440] (II) UnloadModule: "synaptics"

Re: Touchpad cpu to 100%

Okay,

I fixed it and I'm posting my solution so other people having this problem might find their solution !

So I moved my xorg.conf to xorg.conf.d/10-ati.conf.
Next I commented out everything in my xorg.conf.d/10-evdev.conf which I didn't need. Like the section touchscreen, touchpad, ...
Next I put the next few lines in xorg.conf.d/10-synaptics.conf

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

This did the job and made it work properly again...
