Gnome 3.X usually provides window snapping (tiling) and it is triggered by moving a window to the left or right edge of your screen. However, on my desktop this feature isn't working. Moving a window to the edge does not have any effect? How could I activate window snapping in Gnome Shell without installing any extension?


It took my some hours to find out, how to activate this feature. However, if it does not work, try the following command in a terminal:

gsettings set org.gnome.shell.overrides edge-tiling true

To deactivate the feature again, use:

gsettings set org.gnome.shell.overrides edge-tiling false

Mutter is the default window manager for GNOME 3, which led me to the gsetting to change for my installation:

gsettings set org.gnome.mutter edge-tiling true

The desktop overrides, via org.gnome.shell.overrides edge-tiling, seemed to have no effect even after restarts. It would seem that the overrides should replace the mutter configs if I look at the override migration source code. Nevertheless, setting the mutter tiling solved it immediately (no restart required), and it worked with the overrides edge-tiling set to either true or false.

Tested on Ubuntu 18.04.1 LTS, Gnome 3.28.2.
