Hello, how can I use tablet mode? After installation, touch screen is working, but not auto-rotate, and when I overturn the display, keyboard and touchpad is not locked (switched off).
Thank you for your ideas.
So many reads but no answer - so you mean it is not possible? 
Maybe no one has this hardware…
As root. Run evtest. Chose “Intel HID switches” and see what SW_TABLET_MODE says when you fold the screen. It should change from 0 to 1 and back when you fold the screen back and forth.
It looks that it is not listed:

Ok. Do you have intel-vbtn driver loaded? Check with lsmod | grep vbtn. If not, load it with sudo modprobe intel-vbtn and see if that helps.
Unfortunatelly didnt help:
lenovo@localhost:~> lsmod | grep vbtn
lenovo@localhost:~> sudo modprobe intel-vbtn

Ok. That’s unfortunate. I forgot to ask if you have thinkpad_acpi module inserted.
lsmod | grep thinkpad_acpi
OK, I made following… but I didnt catch what should this testing do, so I dont know if I made it correctly… I tried to rotate the screen and see if some values was changing - and it wasnt…
lenovo@localhost:~> lsmod | grep thinkpad_acpi

Then I’m afraid your hardware is not supported by standard methods. However, there are other methods. Years ago I had another Yoga and did my own version of automatic tablet mode. Here is a method that is more sophisticated than mine. There might be other.
OK, thanks… so this is too complicated for me… I will let it as usual notebook
