I also get this problem - randomly (and quite frequently when using keyboard shortcuts to switch around apps & workspaces) the keyboard focus is lost.
A quick double Alt-Tab usually fixes the problem, but the frustration factor is very high. A key culprit appears to be Eclipse - it very frequently does not gain keyboard focus when switched to. I would suggest that diagnostic attempts begin there. If there's any tracing I can enable to help recreate this, please let me know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/757435 Title: keyboard input lost, when window focus lost in unity To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/757435/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
