Macbook pro 8,2, trackpad doesn't do multitouch

Corsair · 2011-08-04 03:28:46

Hi, all. I have a Macbook pro 8,2 (2011, 15 inch model). The trackpad works fine as a single-button mouse. I can move the the cursor, click by pressing down the bottom portion of the trackpad. However, Synaptics and mtrack don't do anything. I write the trackpad setting in /etc/X11/xorg.conf.d/10-synaptics.conf, which is like this:

Section "InputClass"
    Identifier "Touchpads"
    MatchIsTouchpad "on"
    MatchDevicePath "/dev/input/event*"
    Driver "synaptics"
EndSection

Setting driver to "mtrack" does the same thing (i.e. nothing...).

It seems to me that the trackpad is not identified as a touchpad. I know the device node corresponding to it is /dev/input/event1. (I checked by cat /dev/input/event1, then moving the cursor). So I tryed to delete that "MatchIsTouchpad" line, and change "event*" to "event1", so that synaptics is forced to use on that device. Then I cannot move the cursor at all, nor click anything. I'd appreciate it if anyone can shine some light on this.

BTW, here is the output of "lsusb":

I'm not sure if a trackpad is the same as a touchpad, but have you tried https://wiki.archlinux.org/index.php/MacBook#Touchpad ?

Hi karol~ Thanks for the reply. Yes I tried that, and it didn't work, just like Synaptics... :-(
I think "trackpad" is apple's name for a touchpad?

karol · 2011-08-04 03:44:42

Just to make sure: do yo have xf86-input-synaptics installed?

Yes, I do, as well as xf86-input-mtrack-git, as you mentioned.

same issue here, still looking go solution,,,
please share if you find something

Hi groundnuty, I found this post that explains why trackpad and keyboard are not properly identified. It involves patching DKMS, which I don’t use (or I’m actually using it, just don’t know about it... Is it part of the kernel?).

hey,
I managed to get all the media keys + fn working with gnome3 (with X ofc) and with pommed (with X and without) as well. Just "eject" still refuses to do what it supposed to do - but it is correctly mapped to its keycode so thats probbaly some settings issue.
I did extracted patches that I made and send them to devs of DKMS packages - hopefully versions in repo will work out of the box soon,

The wifi is working for me out of the box with latest b43 driver.
Done what is described here without any patches - they seem to be included already.

Touchpad with bcm5974 from their git, it is correctly recognized as trackpad (not pointer) and I managed to get it working correctly with multitouch driver (mtrac refused to deliver even right click).

The order of modules loading seems to be important here is my working setup:
MODULES=( b43 bcm5974 hid_apple usbhid )

Good to know! I'll try dkms and bcm5974. I also got wifi working natively by doing the same as you did. Looks like thing are getting better finally :-)

BTW, for anyone else with problem of BCM4331 wifi, here are some PKGBUILDs for you~~

Hi, using the bcm5974 from git didn't help for me.

What did you exactly do to make the touchpad be recognized like a touchpad? My system still detects it as "pointer" device.

What I did was downloading the git, inside there was a bcm5974.c file that I substituted in place of the one in the kernel and then I recompiled the kernel source. Is this wrong?

If it is how can I make it work?

It seems many multitouch issues are being addressed here, but if anyone is looking just to get their macbook pad to right click (with two-finger tap) I found a simple and elegant solution ... which may be obvious to many, but I could not find it on these forums.

In fact I found it on the forum of my now second-favorite distro:
http://crunchbanglinux.org/forums/topic … n-macbook/

The meat of it is the command "synclient TapButton2=3" which now has me right-clicking to my heart's desire.

On my macbook air 4,2, I ended up having to update /etc/X11/xorg.conf.d/10-synaptics.conf. The issues I was facing was that a) the touchpad would be detected as a keyboard and b) the event id kept changing on me.

        Section "InputClass"
        Identifier "configured Touchpad"
        Driver "mtrack"
        MatchProduct "bcm5974"
        #MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"

And this using aur/xf86-input-mtrack-git as my driver.

Side note ... did you have to "hack" your pommed to get it working ? Dang thing doesn't seem to support the air -_-
