I have the same issue in xubuntu. I narrowed it down to it not working when I click a window when going to a workspace. If that workspace has some spare desktop space in it and you click there instead, then expo keeps working. It seems that giving a window focus from when you are 'zoomed out' results in losing the ability to zoom out again.
I tried to take a video to demonstrate, but it appears that kazam also does not work in xubuntu 13, and I just have a black screen and can only see my mouse moving around. Perhaps this is to do with Mir? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1131106 Title: Expo key stops working after a while To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1131106/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
