This is a quick hack to disable rotation on devices that support it

Installation:

Check out the extension:

     git clone git://honk.sigxcpu.org/git/gnome-shell-lock-rotation.git ~/.local/share/gnome-shell/extensions/LockRotation@sigxcpu.org

Activate it:

     gsettings set org.gnome.shell enabled-extensions "['LockRotation@sigxcpu.org']
