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

[kosumi68]

For me, it is hard to say. The review process is ongoing, I am working on a new release, and packaging takes a bit of time. A guess would be that it first appears as a dkms package on my website, then as a backport in hardy, and then in the 2.6.27 kernel.

I get a problem with loading the bcm5974 module.
This is a printout from my terminal:

FATAL: Error inserting bcm5974 (/lib/modules/2.6.24-19-generic/kernel/drivers/input/mouse/bcm5974.ko): Invalid module format

[kosumi68]

Could you please provide some more information about your system:

uname -r

What version of bcm5974 are you running? What is the output of of this command:

lsusb

Current status of the bcm5974 driver:

* 2 confirmed users on Macbook Air (productId: 0x0223)

* 9 confirmed users on Macbook Pro Penryn (productIds: 0x0230, 0x0231)

* Version 0.42 is the latest stable version.

Version 0.5 is out!

The bcm5974 is now packaged using the dkms utility (available in package manager). Installing should be completely automatic.

The bcm5974-0.5 now works well with synaptics' palm detection.

I would love some feedback on this release, in particular in these areas:

* Installation - does it work well for everyone?

* Stability - can you make it fail in anyway? If you can, please report back to this thread

* Tuning - the Penryn touchpad has slightly different dimensions from the MBA. In order to set the right parameters in the driver, if someone could please turn on the debugging in /etc/modprobe.d/bcm5974, then use the output of /var/log/debug to find out the actual sensor limits, it would be most helpful.

Enjoy!

Version 0.51 just released, with really smooth mouse motion (there was a slight regression in 0.5).

Hi,

I am a very newbi to Ubuntu/Linux. I just installed the deb package provided on the link. V0.51. Then I modified the xorg.conf file.

I logged out and logged in again. But nothing seems to work. Is there anything I am missing here?

Pls help.

Hello RonakG, I will need some more information in order to disentangle the problem.

1. Did the installer complain?

2. Is your mouse pointer not moving?

3. Please run the script /usr/src/bcm5974-0.51/scripts/bcm5974-diagnostics, and post the output here.

The fatal load issue has gone now, but I have the same problem as RonakG. The mouse pointer moves, but when I look in the Xorg log it says it cant find a synaptic device.

Here is the output from the diagnostic:

No help on this one...
