dan, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .
I had the same problem "jumps erratically" if any part of my hand even
lightly brushed the mousepad. This is on an HP dv7.
The problem with erratic mouse was so bad that it was nearly unusable.
I tried Ivan's fix above -- addingOption "JumpyCursorThreshold" "90"
and that solved my probl

Hi folks,
I was able to alleviate this issue to a large degree by the following
change:
edit /usr/lib/X11/xorg.conf.d/10-synaptics.conf
add the line:
Option "JumpyCursorThreshold" "90"
to the area starting with:
Section "InputClass"
Identifier "touchpad catchall"
I still get
I am no longer experiencing this bug so removing my vote. Specifically,
if I press two fingers on my touchpad the pointer doesn't move as long
as I keep both fingers still and in contact with the touchpad.
I had to send my computer for repair for unrelated reasons and they
upgraded the BIOS, maybe
Apologies Maxime. There are four closely related bugs and I'm getting
them terribly confused. There is another bug that IS directly related,
but I can't keep them straight for the life of me. Bottom line appears
to be that there is voodoo in the synaptics driver.

Jim Rorie: It's not the same bug. Note the keywords "jump erratically
all over the screen *constantly* " and "not the same as known bug where
cursor jumps to place on release of finger".
This bug is triggered by having and keeping two (or more) fingers
pressed - the mouse pointer jumps around even
Sorry, not a duplicate but closely related. I think 308191 is what is
making the problem apparent. Upstream appears to have recognized a
similar problem. Some patches are available.

Confirmed for Acer Aspire 5740 running Lucid Alpha 3.
What method does the synaptics driver use for determining multitouch
support? Is it actually probing the hardware, or is it using a
serial/hardware ID table? This seems to be an issue (there's another
large bug report regarding this here:

Another data point. To reproduce the problem:
Place finger 1 on the pad.
Place finger 2 somewhere else on pad.
Lift finger 1. The cursor will slam to a corner of the screen.
What I'm seeing is during two finger scroll, the finger 1 sometime comes
up slightly before finger 2, thus triggering t
I'm seeing this in Lucid Alpha 2 as well on a Sony Vaio.

I have the same problem. I thought the output (attached) of synclient
gives interesting insight on this.
I did the following:
1) I started synclient -m 10
2) (time=2.374) I put one finger near the right of the touchpad, trying to keep
the position and pressure constant
3) (approx time=3.931) Kee
