I am using Ubuntu 11.10 with "Gnome classic (no effects)" at login. Using alt+tab cycles between windows on current desktop. How can I set it to cycle through ALL open windows?
Well, I have done as proposed, here is what happened: when I pressed Alt+Tab, it still showed only window icons from current desktop. Furthermore, I could only switch between the two most recently used windows with a single Tab press. Releasing the Tab and pressing again closed the window chooser.
Another try after logout-login gave another result: pressing Alt+Tab just showed the main menu.
More ideas are welcome.
I had the same problem.
Looking in System Settings → Keyboard → Shortcuts → Navigation, I realized that Alt+Tab combination was assigned to two different options:

Assigning a new combination to the last one solved my problem! I hope this helps you.
Under "System Settings > Keyboard > Shortcuts > System > Show the activities overview" you can set alt+tab, which then should cycle through all open windows and applications, on all workspaces, no matter if active/in use or inactive.
I tested it in Gnome-Classic and it works fine! Please let us know, if that solves your problem!
Edit: Gnome Shell Extensions that might do the job:
A bug has been reported to Launchpad on this issue. Until it's resolved, install Compiz Config Settings Manager, then use the "Scale" settings there to set ALT-TAB as you want it. Works nicely, actually.

Note, this is the default:
