Touchscreen not working in 9.0 r2 k4.9

[Ashutosh prusty]

Hi, I'm using android x86 on my lenovo d330.
I have installed android-x86_64-9.0-r2.iso now & it works fine. But in android-x86_64-9.0-r2-k49.iso my touchscreen doesn't work.
Something wrong with my device or k4.9 branch??

lsmod & dmesg?

You said it works fine in kernel 4.19 version. Right?
Then why did you still want to use the k49 version?
The k49 version is aimed to users who can't use the newer kernel.

It's normal that a peripheral only works in a newer kernel
since the kernel developers have fixed or implemented the driver.
Even you report this issue to LKML, the kernel developers will
just ask you to test the latest kernel to see if it works.

Unless you can prove this is an android-x86 specific issue,
(for example, it works in other distros use kernel 4.9
but not work in android-x86 k49 version)
otherwise I don't see why we should spend time on it.
Sorry!

My bad. Previously i thought 4.9>4.19.

Misunderstanding in my part on version number.

I'm on android x86 r2 & everything works fine except auto rotation.

I checked & it has boschaccelerometer, its using iio & value of x,y,z also changing inside that "device/accel*[x|y|z]*" file.

But android not detecting it, sensor apps says no data. Can that be fixed?

Please check the output of the command:

getprop ro.hardware.sensors

Is it 'iio'? If yes, you may try this first by root:

setprop ro.iio.accel.quirks no-trig
stop; start

If it works, you may add it to /etc/init.sh.
Also provide the output of the command:

cat /sys/class/dmi/id/uevent

Following worked for my device.

set_property ro.iio.accel.quirks no-trig
set_property ro.iio.accel.order 102
set_property ro.iio.accel.x.opt_scale -1

:/ # cat /sys/class/dmi/id/uevent

Thanks for helping, now auto rotation working nicely.
Please add my device to init.sh in next release 😇

Also following for proper camera orientation.
set_prop_if_empty hal.camera.0 0,90
set_prop_if_empty hal.camera.2 1,90

[Ashutosh prusty]

Also z axis need to be inverted.

set_property ro.iio.accel.z.opt_scale -1
