[Lorn Potter]

The Lenovo yoga 460 kernel does not seem to have support for the accelerometer and other sensors.

I can see the same description: "Non-VGA unclassified device" as this thread:

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.9 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

Did not start happening after an upgrade. New install of 16.10.

Yes, I can test a new kernel.

[Lorn Potter (lorn-potter)]

Can confirm that the 4.9.0-040900rc6-generic kernel fixes this issue!
