This problem is not related to Unity. You also do not have to try any of the reported tricks to lose focus.
I have experienced the bug under Kubuntu (KDE). All I have to do is to type in Konsole. Time to time, the window lose focus and my actual typing probably goes to nowhere. The top bar of the window still indicates that the window is the one having focus but it is not true. Since I use the "Focus follows mouse" setting, all I have to do to fix the situation is to move my mouse to another window and back to actually re-focus the window I was originally working in. I am also sure that my mouse pointer still had been in the original window when it lost its focus. I have seen that some people reported using two displays. So if it matters, I use two screen setup, too. Please, set a proper importance level for this bug because working on such a distro is real pain and some serious damages to your work/data could be made. ** Project changed: unity => ubuntu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/865193 Title: Windows keep losing focus in Ubuntu 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/865193/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
