[Bug 1034132] Re: Macbook touchpad cursor moving in steps
dp, 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/ .
If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:
apport-collect -p linux <replace-with-bug-number>
Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc3
This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
As well, please remove the tag:
needs-upstream-testing
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.
** Tags added: needs-upstream-testing quantal raring
** Changed in: linux (Ubuntu)
Status: Confirmed => Incomplete
** Summary changed:
- Macbook touchpad cursor moving in steps
+ [MacBook2,1] Touchpad cursor moving in steps
** Description changed:
I'm on a MacBook2,1, running a fully updated Ubuntu 12.04. When using
the internal Touchpad (appletouch driver), the cursor only moves
horizontally or vertically. When dragging a diagonal line, the cursor
will move in steps, basically rendering the builtin touchpad unusable.

+ In the second post on page 6 describes a solution. In the linux kernel, in appletouch.c, change the following two defines and recompile:
Original:
-
#define ATP_FUZZ 16

#define ATP_THRESHOLD 5
New:

#define ATP_FUZZ 0
-
#define ATP_THRESHOLD 3
-
- and recompile.
I tried this and can confirm that the touchpad is now fully usable.
However, recompiling the kernel takes several hours and *all* of the
disk space on my laptop. Doing this on every kernel update is just not
- practical.

- I would therefore like to ask that this be applied as a patch to the default ubuntu kernel.
- At the very least, please make an optional package containing the patched appletouch driver that can be selectively installed by people having this issue.
