Package: iio-sensor-proxy Version: 3.7-2
Automatic screen rotation does not work in many chromebooks (I have tested this in Acer Chromebook Tab 10 (google-scarlet) and Lenovo 300e 2nd Gen (MediaTek) (google-hana)) due to a bug in iio-sensor-proxy v3.7. The bug also affects most convertible chromebooks and Framework Laptop 12 (see https://gitlab.freedesktop.org/hadess/iio-sensor-proxy/-/issues/411). This bug does not depend on the kernel version, and it is not a kernel bug. A patch has been proposed upstream and I've tested that it fixes the issue: https://gitlab.freedesktop.org/hadess/iio-sensor-proxy/-/merge_requests/400 Please ensure that the patch is included in Debian Trixie before its hard package freeze, otherwise automatic screen rotation will not work in many tablets running Debian.
