Re: Lid sensor on Yoga 11e

[Steven Presser <steve@xxxxxxxxxxxxx>]

Hi Lars,

This happens because the ACPI ID ("BOSC0200") is reused on the Yoga 11e, having previously been used on (apparently) various tablets.  I'm not sure what the best way to do it is, but we probably need to get that driver either a) improved to handle the dual-sensors or b) blacklisted on this hardware.  I'm happy to do the work if someone can point me in the right direction.

On the rotation, the DSDT table has the rotation corrections embedded.  I suspect that Lenovo is using non-standard names on the 11e, since it's non-standard hardware and that that's throwing the existing driver for a loop.

Sorry, one last item on this topic before I turn in.  The kernel driver is only monitoring the screen accelerometer at i2c-2, address 0x19.  The keyboard accelerometer at address 0x18 doesn't appear to be recognized by the kernel, but one can access it over the i2c bus.

...which is all very exciting, and would be even more exciting if it were working correctly.  Unfortunately, the screen orientation appears to be off by 90°...

A problem which can be solved by dropping the following into /etc/udev/hwdb.d/61-sensor-local.hwdb:

sensor:modalias:acpi:BOSC0200:*:dmi:*ThinkPadYoga11e3rdGen*

  ACCEL_MOUNT_MATRIX=0, 1, 0; -1, 0, 0; 0, 0, 1

With that in place, screen orientation is correct...but the device is still stuck in tablet mode, with the keyboard/mouse disabled.
