touchpad no longer works on macbook pro 7,1 after upgrade to 11.04

[phrawzty]

Hello,

After having successfully run Ubuntu 10.x on my Macbook Pro 7,1 for quite some time, I decided to upgrade to 11.04 today. Everything appears to work except for one thing : the trackpad.

Unlike some of the other threads which report unstable or inconsistent behaviour, my condition is entirely consistent : it simply doesn't work. No clicking, no scrolling, no moving of the pointer - it is as if the trackpad doesn't exist.


$ sudo dmidecode -s system-product-name
MacBookPro7,1


$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ HID 05ac:820b id=13 [slave pointer (2)]

I am open to any ideas. :)

Thank you !

What does your xorg.conf look like?
Also, what does this give you:

cat /var/log/Xorg.0.log | grep -i trackpad

I am not seriously skilled to help but I'd try a live 11.04 cd and check if the trackpad works from there.
If so I'd just reinstall it from scratch: not always an upgrade works flawlessly (in my experience).

Good luck with your hunt anyway :)

I've attached my xorg.conf(.txt) - nothing special as far as i can see.

As for the Xorg.log, the trackpad is clearly identified (which is a good thing) :


$ cat /var/log/Xorg.0.log | grep -i trackpad
[ 43.170] (II) config/udev: Adding input device Apple Inc. Apple Internal Keyboard / Trackpad (/dev/input/event10)

Still no activity from once i'm in X, though. :(

In fact, on second look, that's not true - the trackpad section at the end is, in fact, superfluous. After commenting it and rebooting my trackpad became operational (yay).

Thanks phrawzty! (http://ubuntuforums.org/member.php?u=83427)
I had the same issue (after an update from 11.10 to 12.04) and commenting it out the trackpad section in the xorg.conf solved the problem!

Thanks so much!
