Recently installed ubuntu 14.04 and gnome shell 3.10.4 on a dsktop with 2 screens connected.
When switching workspaces (ctrl + alt + up/down) I want both displays to change, but only the primary display changes (the secondary stays static with the same windows.)
Installing 'gnome-tweak-tool', turning 'Workspaces only on primary display' off did not help.
Couldn't find any other suggestion online.
Please help! Thanks!
