How to enable the landscape mode on the default launcher on Android Marshmallow? I can read on various news websites that in Android 6 Marshmallow, it is possible to rotate the screen on the launcher.

I can't find any setting about this on my Nexus 5 and when I activate automatic rotation, it doesn't rotate on the launcher. 

Any idea how to enable this feature?
Auto rotate Home screen was one of the top features of 2nd Android M Developer preview.
I hate to burst the bubble, Auto rotate home screen feature was not incorporated in the final version of Android Marshmallow 6.0.  


  We're  disappointed to see that auto rotate support hasn't made it to the home screen, however. In the second developer preview, the Google app added an "allow rotation" option to the home screen settings, which let the home screen rotate like any other app on the system. We loved it. It never made the jump to the final version, though.

However, if you have got a rooted phone, you can modify build.prop file to get this feature.  


Navigate to and open /system/build.prop file using any Root explorers  
Add log.tag.launcher_force_rotate=VERBOSE at the end of the file 
Optional step: Add lockscreen.rot_override=true to enable screen rotation in your lock screen  
Reboot to see the feature working!
