[SOLVED] Apple Magic Trackpad issue

UPD: solution is in the 6th message of this thread. Also, this seems to be fixed upstream (I'm not sure, though)... Anyway, I had this line by default on my new setup. So no manual work needed.

Hi, I've just bought Apple Magic Trackpad which I'm going to use with my Arch installation.
I've tried to make this thing to work for more than 5 hours, but succeed with it's setup only twice. And seems, like it succeeds with no explicit reason. Thing works only on approximately every 50'th reboot .

Here is my xorg.conf.d/60-magictrackpad.conf file

Section "InputClass"
 Identifier "Magic Trackpad"
 MatchUSBID "05ac:030e"
 Driver "synaptics"
 Option "SHMConfig" "True"
EndSection

Here is dmesg output

Please, help me to resolve this issue.

Thanks in advance.

Re: [SOLVED] Apple Magic Trackpad issue

All works great in Ubuntu 11.10. Touchpad remains connected after reboot and also Ubuntu recognizes up to 4-finger taps (I only had to install latest updates to eliminate known bug with pairing over bt).
Here is Xorg.0.log from Ubuntu

Also I've tried mtrack driver under arch and found that udev removes device right after corresponding module is loaded

Any ideas, what could be the cause of that issue?

P.S. btw, is there any way to change name of bluetooth hid device under linux? These Cyrillic symbols in console drive me insane >_<

Re: [SOLVED] Apple Magic Trackpad issue

Hello,

if it comes to such message:

[   38.993692] magicmouse 0005:05AC:030E.0003: unable to request touch data (-5)
[   39.030209] magicmouse: probe of 0005:05AC:030E.0003 failed with error -5

I have the same once I switch to kernel 3.X. So the mouse doesn't work. But, if I reconnect mouse through KDE bluetooth setting it works well. I think this is an issue with pairing or udev ...?

Kr.,

Piotr.

Re: [SOLVED] Apple Magic Trackpad issue

Pjoter,
connecting via KDE gui works from time to time. Sometimes it works, and sometimes not. That's the problem I have to spent up to 2 hours for my trackpad to start functioning accidentally.

I will try to make thorough comparison of Ubuntu's and Arch's udev rules. Perhaps will find the cause of such weird behavior of Arch's udev.

BTW, If no luck, will try Ubuntu as the primary OS. The latest Ubuntu seemed to be very stable for me and also Unity provides great experience!

Re: [SOLVED] Apple Magic Trackpad issue

Thanks, Pjoter

I've already migrated to Ubuntu, and only after that found magic line in xorg.conf that perhaps could resolve my issue

      MatchDevicePath "/dev/input/event*"

Here is a blogpost which explains necessity of that line
http://who-t.blogspot.com/2010/11/how-t … rrors.html

I don't know if it actually works, but worth to try if someone has the same issue.
