I used to have a lock orientation button in the top right gnome menu. Now this is gone and the screen does not rotate anymore.
I would say that may a reboot will bring it back, or it is disabled, do you take a look into gnome display settings? may there is something related to set?
As this is only there if you have an iio-sensor inside the machine, it is not visible on systems without iio-sensor…
I find this gsettings command to enable the feature:
gsettings set org.gnome.settings-daemon.plugins.orientation active true
possible also that the driver or recognition of your iio-sensor is broken, but to see this logs-please-mr
That option returned an error:
No such schema “org.gnome.settings-daemon.plugins.orientation”
There are orientation settings in settings-app but thats for static monitors. I have not looked in to the logs yet, other strange things are going on as well. This is a laptop, I reboot all the time .
I make things work…
