I'm not convinced that this is a duplicate of " Bug #868400: Synaptics
touchpad stops working - two syndaemon instances running." since I do
not have two instances running that I can find (ps -ef doesn't show 2).
Things I have noticed, though:
- I don't know that it's 100%, but it's much more frequent when "Disable
mouse when typing" is set. This is my usual setting on boot since I use
a USB mouse most of the time specifically because of this problem.
- It acts as if the touchpad is "locked" into some gesture state. In
particular, when the mouse won't move, instead a one finger gesture on
the touchpad results in TWO-finger vertical scrolling. I.e., as if it
thought it was still in two finger mode when I'm only using one finger.
(Was state saved/not cleared when the touchpad was enabled/disabled?)
I've had other cases where some motion seemed to "reset" it to a known
good and working state, but not reliably. But it looks like a state-
holdover somewhere to me.
- The touchpad isn't "off" -- it is clearly responding and scrolling --
although it should be interpreting a single finger gesture to move the
mouse, not to scroll as it is doing.
- I'm not positive about this, but I think I even had "enable mouse
clicks by touchpad" set one time, and when in the bad state, it would
not respond to mouseclicks either.
This is Ubuntu Desktop 32-bit, 12.04 and up to date as of 02/18/2013, on
Asus 1215N netbook. The only odd thing about the install is this is the
Nvidia Optimus graphics, so I have both Jupiter and Bumblebee installed,
but only to disable the fast graphics Nvidia card (using Intel only) to
save on battery and heat.
Settings are:
- Disable touchpad while typing
- Enable 2 finger (vertical) scrolling
- Speeds set all the way to left (slow)

Title:
Synaptics touchpad randomly stops working
Status in “gnome-settings-daemon” package in Ubuntu:
Confirmed
Bug description:
From time to time the touchpad stops working, usually noticed by the cursor
'freezing'
This has affected a number of users.
At least here & for some others disabling the option "Disable touchpad while
typing" has apparently stopped this from happening, though due to the sporadic
nature can't say for 100% sure. (tested here for 3 days, no occurrences
When it happens this frees up the cursor/touchpad
synclient TouchpadOff=0
Now have been enabling the option thru syncdaemon instead & again have seen
no occurrences
To do so - first in a terminal disable syndaemon starting thru g-s-d
gsettings set org.gnome.settings-daemon.peripherals.touchpad disable-
while-typing false
Then create a Startup Application,
gedit ~/.config/autostart/syndaemon.desktop
Using this currently, check man syndaemon for other possible options
