Comment 42 for bug 320632

Using 0.99.3-2ubuntu1 on an Acer Aspire One, something truly bizarre is happening.

Immediately after login, edge-scroll works. Shortly after login, edge-scroll stops working. When this happens, 'xinput list-props' and 'synclient -l' *DISAGREE* about the position of the right edge of the touchpad!? - see here:

maxb@aao:~$ synclient -l | head -5
Parameter settings:
    LeftEdge = 1632
    RightEdge = 6143
    TopEdge = 1575
    BottomEdge = 4281
maxb@aao:~$ xinput list-props 5 | head -3
Device 'SynPS/2 Synaptics TouchPad':
 Device Enabled (109): 1
 Synaptics Edges (255): 1632, 5312, 1575, 4281

Using 'synclient' to reset the RightEdge value to what 'xinput list-props' shows throughout *re-enables* edge scrolling.... for a while. After a minute or so, edge scrolling breaks again, and inspecting the RightEdge value with 'synclient -l' shows that it has mysteriously reverted to the broken value, apparently spontaneously !?

I will attach the full 'xinput list-props' output for both 0.15.2 and 0.99.3, though I have summarized the interesting bit above, AFAICS.
