Ubuntu 20.04 with Gnome 3.36 used to rotate screen automatically when I rotated the device, the new Ubuntu 20.10 with Gnome 3.38 doesn't do it. I've tried with ctrl+o
to see if the automatic rotation is locked, it isn't. I already have installed and updated iio-sensor-proxy
.

Not an "answer," but can't comment with my rep:
This seems to be a bug in GNOME 3.38. Screen rotation stops working even though iio-sensory-proxy
and monitor-sensor
indicate all is working properly. It also appears to distribution agnostic (i.e., it occurs on Ubuntu, Fedora, and Manjaro).

Thank you, I was scared it could be a problem of the hardware. Is there a way to return to Gnome 3.36? If it is, is it convenient? – evening_g Nov 10 '20 at 01:08

It appears that the bug has been fixed in GNOME 3.38.2, which looks like it landed in the Ubuntu repositories at the end of December. Has upgrading worked?
You'll also notice in that thread the recommendation of using ScreenRotator as a temporary fix.

I'm not able to say if the upgrade worked since I'm now using KDE Neon, but I'm closing the question since your answer – evening_g Jan 13 '21 at 03:24
