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.
