Assuming I'm using intel's driver.
Gnome-shell allows to rotate screens in Settings -> Display when using Xorg.
Is it possible to rotate when using Wayland?
There is no setting available in the BIOS to change the orientation. The Graphics driver in the BIOS does not support display rotation. Only the default portrait mode is available until Windows boots and its graphics drivers are loaded.
Just press "Ctrl-Alt" and any arrow key to rotate the screen.
I had the problem with no screen rotation buttons in the monitor settings in my Lenovo Yoga 910 laptop, which is a convertible.
After Gnome started to randomly flip the screen I disabled automatic screen rotation via:
gsettings set org.gnome.settings-daemon.plugins.orientation active false
and suddenly, I've got these buttons!
GNOME's Mutter supports screen rotation on Wayland since 3.20, and 3.22 has improved it. https://wiki.gnome.org/ThreePointTwentyone/ReleaseNotes
