[SOLVED] New kernel driver for the BCM5974 touchpad (Macbook Air, Penryn)

[muryoh]

Hello
I'm using the new 6.2 Macbook Pro.
For some reason, my trackpad won't work on Gentoo, and I can't figure why. I tried Ubuntu 10.04, and it does work without any tweaking. I don't know why! I do know that when the usbhid module isn't loaded, the trackpad works fine.

I'm not up to date with usbhid or udev, but it does sound like a quirk issue. Could anybody provide me with the tweaks performed on previous releases of Ubuntu to get the trackpad to work fine with usbhid?

Thanks.

Hi, do you use a ramdisk when booting up?

i'm havin problems with the trackpad and keyboard on a penryn macbook - due to my dmesg it's propably an issue with the bcm5974 driver...

dmesg output:

Hi, thanks for the report. I am sorry, but this sounds like a known hardware (usb) problem. You will find references by searching for "ubuntu macbook disabled by hub (EMI?)".

[muryoh]

Hi, do you use a ramdisk when booting up?

I apologize for the long delay, I'm the one asking yet I'm the one forgetting about the post...
No, I'm not using a ramdisk.

[muryoh]

ok, got it. Sneaky kernel options did the trick : https://bugzilla.kernel.org/show_bug.cgi?id=14987

Thanks

Has anyone else started to have problems with this driver recently? Overall it has worked wonders and on the odd occasion it would stop working I'd just toggle to text console rmmod+modprobe and a few seconds after switching back everything was fine again. Yesterday this no longer helped so I tried restarting X - still broken. Note that seemingly any variant of clicking (right left depending on number of fingers - but I've intentionally disabled tapping) still worked, just moving failed. In the end I rebooted and it was fine.

This morning it was the same again (I'm currently using a USB mouse).

Any and all suggestions are welcome. This is on a MacBookPro6,1 upgraded to Natty about a month ago. I've run Ubuntu on it ever since I got it (within a month or so of its release) and the module has never misbehaved before.

[Hmm, Seems like a "Heisenbug": I tried adding some debugging to the module and suddenly it worked again! Very annoying. ]

[JonasPetersson]

For the record, it just happened again and this time it stayed broken after i modprobed with debug=8. The situation is identical in that clicking appears to work, but movement hardly ever does anything. The debug flag yields some lines like these in dmesg:
[836847.062151] bcm5974: switched to wellspring mode.
[836847.077168] bcm5974: abs: p: +0255 w: +0015 x: +0402 y: +0396 nmin: 1 nmax: 1 n: 1 ibt: 0

That seems to indicate that report_tp_state() is called with fingers pressed (makes sense considering what I see) and that bcm5974_wellspring_mode() is called with on==true - whether that makes sense is somewhat beyond obvious to me at the moment...

Any and all hints are welcome.

The synclient command does not work on my Macbook Pro 7,1 using Ubuntu 11.04. When I'm typing on the keyboard the touchpad responds to clicks/movement. I believe I can use syndaemon to disable the touchpad while typing.

$ synclient -m 500
Can't access shared memory area. SHMConfig disabled?
Couldn't find synaptics properties. No synaptics driver loaded?

The bcm5974 diag script:

$ /usr/src/bcm5974-1.1.9/scripts/bcm5974-diagnostics

Can anyone point me in a direction to get the synclient working?

Similar story for me.

MacBook Pro 4,1 Natty 11.04

I'd say it started a month ago and just got worse over time.
I have found out this:

Apple keyboard and touchpad share a USB port or something like that. Hence we need a mode switch - so I gather.

With touchpad bcm5974 removed, apple keyboard works fine.

With apple keyboard hid_apple removed, touchpad works fine.

With both loaded, both eventually become unusable and my USB hub seems to
reset all the time and xorg loads and unload it's drivers making my situation unworkable.

I too am using a USB mouse.

This morning I thought it might be hardware since with a cold laptop, my machine was usable but as it warmed it got worse and eventually became unusable.

But, on OS-X all is well. So must be a driver issue - perhaps hid_apple?

How can I help?
