The command that I am trying to run is:
gsettings set org.gnome.shell.overrides edge-tiling false I get the message saying No such schema 'org.gnome.shell.overrides' error.I am currently using ubuntu 16.04.
Are you certain that the gnome-shell package is installed? Those keys are added when installing the shell.
Incidentally, the contents of my XDG_CURRENT_DESKTOP variable on my GNOME 3 setup is:
$ echo $XDG_CURRENT_DESKTOP ubuntu:GNOME You can also use the Mutter window manager (used by GNOME 3) to effect the tiling via:
gsettings set org.gnome.mutter edge-tiling true
