Abnormal touchpad behavior on MacBook Air A1466 EMC2559

Support
1

Hello,

Requirements:

I have Searched the forum for my issue and found nothing related or helpful
I have checked the Resources category (Resources Index)
I have reviewed the Wiki for relevant information
I have read the the Release Notes and Errata

OpenMandriva Lx version:

OpenMandriva Lx release 25.06 (ROME) Rolling for x86_64 kernel Linux 6.14.2-desktop-3o

Desktop environment (KDE, LXQT…):

KDE Plasma 6.3.4 (Wayland)

Description of the issue (screenshots if relevant):

Abnormal touchpad behavior on MacBook Air A1466 EMC2559.

The physical buttons do not respond at all. Additionally, the pointer only moves verically when I slide my finger from right to left, and it moves to the right when I slide my finger up or down but only if I down one of the two buttons. The only function that works correctly is two-finger scrolling.

Relevant informations (hardware involved, software version, logs or output…):

Please fix this and indicate what you have tried.

We will require you to verify this is an issue in X11, as well. If possible, make sure you are not using the Slim version. It is more debloated than a full version and may require manual package installs as a byproduct.

Thanks for fixing, but it appears you missed something:

This may also be relevant:

We don’t appear to currently package mtrack so this is probably a @bero question. It will most likely be a module.

Thanks for your reply.

Yes, I saw that discussion, but unfortunately there is no solution to the problem there. :cry:

Thank you very much. I will definitely read it.

What bothers me is that I also tried the Mageia and Openmamba ISOs, and the touchpad worked fine with both of them (they had other problems, though :winking_face_with_tongue: ). It almost makes me think that it’s something that needs to be activated in the kernel.

OMLx is not based on those, it is independent. You could run a live disk of those distros and check which modules are loaded for input.

Don’t forget to try this.

Yes, I understand. I meant that it would be interesting to understand where the difference lies. I should do some cross-testing with OpenMandriva.

You’re right, sorry I forgot to reply earlier. Before installing the full ROME version with Wayland, I tried almost all the available OpenMandriva ISO images, both slim and full, with X11 and Wayland, and with other graphics daemons. But all versions gave me the exact same problem. :cry:

7

Then, yeah. It’s probably a module problem. Your success rate will increase using X11 as we don’t support Wayland for production level work. This means you use (test) it at your own peril.

I had experienced this issue a while back with a MacBook Pro from the same era. I searched online and found a post that said to check for the bcm5974 module being there (which is the correct one), and it was for me on OMLx ROME. It also stated to check for the usbmouse module, if it was there (it was), then remove both and load bcm5974 again. Those steps worked for me on ROME with x11. Obviously, other action would need to be taken in order to get that to be permanent. Also, there would be a matter of your wireless card if that’s an extra fun model like mine was. Those laptops are an extreme myriad of traditionally unfriendly hardware.
