Force alt + tab to switch only on current workspace in GNOME shell. Here is the solution I came up with:
Very fast & easy, without any installations/extensions:
-
Install
dconf-editor
(already installed on current debian/ubuntu distributions):sudo apt-get install dconf-editor
-
Open
dconf-editor
(from the Dash or a Terminal) -
Navigate to: org -> gnome -> shell -> app-switcher
-
Set "current-workspace-only" to true
..and you're done :)
