[Lenovo Yoga 7] Autorotation of screen does not work on wayland, but on X

[MichaelE]

When physically rotating my 2-in-1 laptop Lenovo Yoga 7 Gen 6 AMD - 14ACN6, screen rotates properly under X, but not under Wayland.
Also the lock screen rotation option is missing in the top-right menu under Wayland. It exists in X.

iio-sensor-proxy is being loaded correctly:

monitor-sensor detects the physical rotation:

Putting the laptop in tablet mode disables keyboard and touchpad correctly both under Wayland and X.

So obviously the sensors are working correctly, but signals are not being interpreted correctly in Wayland?

It looks like there were a few rotation fixes upstream in mutter in the past year or so, so maybe this has been fixed already.

Unfortunately you can't test it in a live session because live sessions use Xorg still. We'll need to wait until you are able and willing to try Ubuntu 22.04, which will be formally released in April.

[Daniel van Vugt (vanvugt)]

If you are able to wipe the machine and test 22.04 early then it can be downloaded here:

Ok, moved to 22.04 early (5.15.0-18-generic) and am still seeing the same behavior. It works with X, but not with Wayland.

[MichaelE (michael-eitelwein)]

I think this relates to this discussion on GNOME: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1846 and https://gitlab.gnome.org/GNOME/mutter/-/issues/1686.

My Laptop also does not report SW_TABLET_MODE, while disabling of keyboard and Touchpad is done properly by the HW (?) when folding into tablet mode.

Obviously, the way X is deciding on the sensor input is the better one, as there the behavior is as expected, when folding the laptop.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Gavin Graham (gavingraham)]

I have a Lenovo Yoga 7 Gen7 (14ial7) 12thGen Intel CPU and I am having the exact same issue. Monitor-sensor reports everything is correct and yet the rotation doesn't work under Wayland but it does with X.

Only adding a comment here are this is another model number of a 2-in-1 exhibiting this issue. I can collect hardware info but I have attached the output of lshw.
