I used instructions from following website:

http://askubuntu.com/questions/77160/how-can-i-tell-what-workspace-i-am-
in-with-unity

Then I installed the deb package from the link on the website and put 
indicator-workspaces in startup applications and restarted.

Then I get number 1 in the panel, but it stays at 1 even when I change 
workspace.

Then I went to preferences in this nr 1 box in the panel and then I can 
change the workspaces to show in one row like in old gnome 2x but the 
number stays at 1
