Public bug reported:
After some time (randomly) the touchpad stop working correctly.
i'm on a acer aspire 5943g. This is the a grep of my Xorg.log:

I debugged a little with synclient. Normally (as stated above) the touchpad
area is from 1472 to 5744 for the x-axis and 1408 to 4792 on the y-axis.
When this happen:
1) touching the right side i get x: 5800 (correct), istead on the left side
5600(incorrect). So it's like the x coordinate isn't read correctly on the left
side of the touchpad.
2) Related to the first issue, doing the same thing in an area close to the
bottom-right corner i get a value of x that range from 5000 to 5700. Thus the
touchpad somehow works on the bottom right area.
3) However if i touch on the right area and move to the left area without
removing the finger the x coordinate correctly range from 5800 to 1100!!
4) the other issue it's the wrong number of fingers. Again touching on the
bottom-right corner i get one finger (correct), instead on the left side 2
I didn't find the reason that generated this bug, so i can't reproduce
it. Looking at the xorg logs or dmesg i didn't notice any error message.
