How to turn off Sticky Edges in Ubuntu Gnome [duplicate]
Solution 1:
Sorry for the late answer, but better late than never?
The setting you are looking for can be done graphically in dconf-editor, navigating to /org/gnome/shell/overrides and toggling the value edge-tiling, as appears below:
To do this using a CLI, enter the command
gsettings set org.gnome.shell.overrides edge-tiling false
to turn off the tiling at the edge of the screen, or
gsettings set org.gnome.shell.overrides edge-tiling true
to set it back on.
