Touchpad suddenly stopped working

To be specific: TwoFingerScroll doesn't work and other things like this. Just moving and clicking is working now.
I don't know why but it stops
I can't figure out why, i;m sending everything i think is important.

Found your problem, I think. 

Section "InputClass" 
   Identifier   "touchpad catchall" 
   MatchIsTouchpad   "on" 
   MatchDevicePath   "/dev/input/event*" 
   Driver      "synaptics" 
   Option      "Device"   "/dev/input/mouse0" 
   Option      "Protocol"   "auto-dev" 
   Option      "LeftEdge"   "1700" 
   Option      "RightEdge"   "5300" 
   Option  "TopEdge"       "1700" 
   Option  "BottomEdge"    "4200" 
   Option  "FingerLow"     "25" 
   Option  "FingerHigh"    "30" 
   Option  "MaxTapTime"    "180" 
   Option  "MaxTapMove"    "220" 
   Option  "VertScrollDelta" "100" 
   Option  "MinSpeed"      "0.7" 
   Option  "MaxSpeed"      "0.8" 
   Option  "AccelFactor" "0.0010" 
   Option  "SHMConfig"     "on" 
   Option  "VertTwoFingerScroll"   "1" 
   Option  "HorizTwoFingerScroll"  "1" 
   Option  "TapButton1" "1" 
EndSection 

Get rid of SHMConfig, that makes things temporary, so that any changes you make will be reset when you reboot see the  Touchpad Synaptics Wiki page for more on SHMConfig and configuring synaptics in general.
Check the wiki page and see if that, along with my config below, helps any.

$ cat /etc/X11/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"
	Option "VertEdgeScroll" "on"
	Option "HorizEdgeScroll" "on"
	Option "VertTwoFingerScroll" "off"
	Option "HorizTwoFingerScroll" "off"
#	Option "CircularScrolling" "on"
#	Option "CircScrollTrigger" "2"
	Option "CoastingSpeed" "0"
EndSection

I'm also currently sort of working on a perl script that can be used to configure synaptic touchpads on the fly using Synclient--a command-line utility that is part of xf86-input-synaptics, I believe--if you'd be interested in getting a piece of that when I'm done with it, or/if I decide to just stop where I am.  Currently it can be used to enable/disable scrolling.  Note that this can also be done directly using synclient easily enough.  I'm just writing a perl script because I think it's cool, 'cause I like the idea of another abstraction layer, and I also enjoy writing small but useful utility-like scripts.
