I have a dual monitor setup with an internal laptop monitor and an external VGA monitor (extended, not mirrored). When I now switch workspaces, this only happens on the internal monitor; windows on the external monitor are always "sticky"!
What I would want is the workspace stretching over both the internal monitor as well as the extended external monitor, and switching workspaces should have the same effect on both monitors.
I do not want to establish separated workspaces on each monitor which are switchable individually. This is a feature for which I found several questions here on the platform, but for my specific problem I was not able to find a solution or even a matching question...
My system is an Ubuntu 13.10 (currently with Gnome Shell) with kernel 3.12. The laptop has an nVidia Optimus graphics adapter; I basically always rely on the precessor's internal graphics adapter.
Thanks in advance!
I resolved the issue now. It turned out that it is actually a Gnome problem, this is why I did not find anything with my Ubuntu related search attempts.

The desired behavior is activated by executing
gsettings set org.gnome.shell.overrides workspaces-only-on-primary false
in a shell.
