Re: [Mactel-linux-users] Problem with appletouch

[M. M. <mma...@gm...>]

Hi.
It works !!! :D evtest detects input now and trackpad works with X.
The only problem is that it is "unstable". It moves like crazy. Of
course I have a control over it but when I move it to upper left
corner it can "jump" to the right corner without any reason. I did
post my Xorg config so please let me know if it is something wrong
with the synaptics driver configuration or do I have to "tweak"
appletouch in some way?
Regards Michal.
