good evening everyone,
I've installed 12.10 on Macbook2,1 with 1GB ram. Unity was working but due to hardware restrictions I had to install gnome-sessions-fallback and going back to previous gnome.
in this environment it's usable but I can't have the Switching Windows Shortcut working. When I press the Alt+Tab the windows are not switching. If I open the Keyboard settings, in the shortcuts->navigation I have Alt+Tab selected. I tried changing with different combinations but none of them is working.
