Trackpad becomes unresponsive. Unrelated to sleep wake.

After a period of time the trackpad becomes unresponsive or disconnects. A restart is the only fix. Using your stock EFI with unique SMBIOS.

This is the same problem I get with the simpreciciani project, but that was prescribed for T460... does this kreizlie EFI support Monterey, so I try it?

[galaxy-nomad]

I don't know about Monterey but I may have solved the problem at least with Mojave. Disable the track-point (Red button in the middle of the keyboard) in your BIOS and see if you have a crash or disconnect. I did that and did not have a crash after a half-day of use.

[robertojguerra]

I will try it... and I forgot to mention: I use a Yoga 260 running Monterey 12.0.1

[galaxy-nomad]

Oh that's exciting to hear. I run a 2014 macBook Pro which officially cannot run Monterey but have my Yoga 260 waiting for more memory (it's unusable for me with 8GB) Photoshop freezes up🤣 How is Monterey? Do you have 16GB of Memory? Are you using this EFI with Monterey?

[robertojguerra]

I have 8GB in my Yoga 260 and Monterey runs fine :)
However, I am not using a Broadcom wifi... using Intel... which was working fine in BigSur but not so well in Monterey (interface disappears in about 1 hour).
So far I am using the simprecicciani EFI.
I am still getting the kexts in the kraizlie EFI folder

[galaxy-nomad]

Yes for me I could not get Intel Wifi working at all with Mojave. With Intel wifi any local Wifi Network will not show up at all and then it just will not connect and you cannot use wifi at all. Since the Yoga 260 does not have ethernet you're basically dead in the water without buying a USB ethernet adapter. The Broadcom card that Kreizlie recommends works PERFECT!!! I bought that card and the adapter and it's just as good as a MacBook Pro and everything works. 8GB of RAM was fine for normal tasks but as soon as I tried to do my usual photo editing, PhotoShop would just freeze like it could not figure out what to do next.🤣 I assume it was because of low RAM.

[robertojguerra]

The kreizlie EFI did not boot Monterey... it resulted in the famous [EB|LOG:EXITBS:START] <date,time> error before even booting the kernel... and I saw that the included OpenCore is REL-059, not 0.6.7 as implied in the GitHub release.

[galaxy-nomad]

So you're saying the simprecicciani EFI works perfectly it's just the trackpad freeze that's the issue?

[galaxy-nomad]

Btw do you have a link to the simprecicciani project? I might be spelling it wrong but I did not find anything under that name here at GitHub.

[robertojguerra]

Yes. the simprecicciani EFI boots Monterey in the yoga 260... only change is to include alcid=15 in the bootargs.

Nice one. Thank You! Please let me know if disabling the track-point works for you. I'm pretty sure that was the issue with freezing touchpad but would be nice to hear from someone else to help confirm my findings like a science experiment🤣

[robertojguerra]

disabling trackpoint: so far, so good! 1.5 hours trackpad alive...and surviving one sleep

[galaxy-nomad]

I got so excited I decided to move back over to my Yoga 260. I've been on it all day with heavy use and no trackpad freeze and everything running smoothly.😁

[robertojguerra]

For some reason, my physical buttons stopped working, and I am left with tap-to-click and two-finger-tap to right click. The malfunction extended to the right click in Windows and Ubuntu.

But the trackpad stays on indefinitely!

Cyberfunk, if you try Monterey beware that the native broadcom might or might not be supported. Test it in an external drive.

[galaxy-nomad]

My physical buttons do not work either. They worked very briefly when I first setup my Yoga a while back and then they stopped working shortly thereafter and have never worked again. It might have something to do with a config or setting in Kreizli's EFI. I don't mind because the Yoga 260 trackpad is like the MacBook pro trackpad in that you don't even need buttons and you can use multi touch gestures to replace right click left click etc. One tool I HIGHLY recommend is "Better Touch Tool" https://folivora.ai/ I use it with my MacBook Pro and it works just as well if not better with my Yoga 260 because you can also remap keyboard keys like F1, F2 and other buttons to do whatever you wish!! This program is so incredible and after MANY years using it I have still barely scratched the surface. It also does window snapping and so much more. I have mapped three finger trackpad click as "right click" and use this mod for years on MacBook pro as well. Try it out! I find it very intuitive and you have no mistakes like two finger gestures. Thanks for the heads up on Monterey😁
