Macbook touchpad cursor moving in steps |
[MacBook2,1] Touchpad cursor moving in steps |
|

description |
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.
This issue is also described in a forum thread: http://ubuntuforums.org/showthread.php?t=813884&page=6
In the second post on page 6 describes a solution. In the linux kernel, in appletouch.c, change the following two defines:
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.
