Nonfunctional touchpad on Acer AS4830T-6678 [solved]

Just setup a new install on an AS4830T-6678 but cannot seem to get the touchpad to work at all. 

The kernel sees it:

# dmesg | grep -i touch
[    7.471862] psmouse serio1: synaptics: Touchpad model: 1, fw: 7.5, id: 0x1e0b1, caps: 0xd00073/0x240000/0xa0400
[    7.603935] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input16

I have xf86-input-synaptics installed which provides the default /etc/X11/xorg.conf.d/10-synaptics.conf which I haven't modified:

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

Per the wiki, it seems as though the touchpad is getting loaded twice, but I have the 'matchdevicepath' line the my 10-synaptics.conf which is known to fix this.  I have also tried commenting out the 'evdev touchpad catchall' section in /etc/X11/xorg.conf.d/10-evdev.conf but this has no effect after a restart of X:

#Section "InputClass"
#        Identifier "evdev touchpad catchall"
#        MatchIsTouchpad "on"
#        MatchDevicePath "/dev/input/event*"
#        Driver "evdev"
#EndSection

I posted my /var/log/Xorg.log and would be grateful if someone can suggest a course of action.  Thanks!

Just backup your old configs and try those:

For 10-evdev.conf

Section "InputClass"
        Identifier "evdev pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev keyboard catchall"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

for 10-synaptics.conf

Section "InputClass"
	Identifier	"Synaptics touchpads"
	MatchIsTouchpad	"on"
	Driver		"synaptics"
	Option		"TapButton1"		"1"
	Option		"TapButton2"		"2"
	Option		"TapButton3"		"3"
	Option "VertEdgeScroll" "on"
	Option "VertTwoFingerScroll" "on"
	Option "HorizEdgeScroll" "on"
	Option "HorizTwoFingerScroll" "on"
	Option "CircularScrolling" "on"
	Option "CircScrollTrigger" "2"
	Option "EmulateTwoFingerMinZ" "40"
	Option "EmulateTwoFingerMinW" "8"
EndSection

It will most likely work.

Good luck!

I actually confirmed that the touchpad does not work under any OS and returned the laptop.  Thanks for the post though.
