Hey Davide, I am experience similar things with the Thinkpad Yoga 370 and I think Lars Kellogg-Stedman on the thread "Detecting tablet mode on Yoga 11e" might have the same issue. I found that the thinkpad_acpi driver indeed reports the correct tablet mode on my device to /sys/devices/platform/thinkpad_acpi/hotkey_tablet_mode. The event triggering this is the 0x60c0. I am not sure what the 0x60f0 is but it is an additional event. Nevertheless the screen rotation doesn't work on my system. I tracked my problem down to a faulty iio acceleration sensor. Have a look at the output of 'monitor-sensor'. Is the iio-sensor-proxy reporting values? If not, like in my case, we have indeed the same problem. Which is the iio device not triggering a event and the device software buffer doesn't get values. I reported the issue here: https:// github.com/hadess/iio-sensor-proxy/issues/164 I talked to a guy who fixed the issue for an older yoga and he told me that he had to fix the hid-sonsor-hub and add a quirk for the sensor. If we really have the same issue here we might work on this on a different channel because it doesn't concern the thinkpad_acpi driver. Hope that helps!
