Good to know. From the back of my mind, I can confirm that running Firefox, vim, Terminator, or Gedit in the foreground does not affect the lock screen. In other words the bug lies with the interaction between Unity Lockscreen and Google Chrome.
Also, related to my previous comment, forget what I wrote there. I think `workaround-screen-lock-malfunction_1_all.deb` is meant to fix something else, and so is totally unrelated to this bug. I have had the issue after installing it. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu. Matching subscriptions: dx-packages https://bugs.launchpad.net/bugs/1348668 Title: Unity lockscreen lets applications capture keyboard input Status in “unity” package in Ubuntu: New Bug description: I noticed that with the Vimium extension activated in Google Chrome, I cannot unlock Unity's lockscreen because keyboard input is hijacked by Vimium. The lockscreen really should not let this happen, and it can even be considered a potential security vulnerability as it might allow applications to capture a user's password. I have noticed this before as well when using another application, though I can't remember which one it was at the moment. The workaround is to use the mouse to choose the Switch user-option, but this is really not obvious to anyone who might encounter this bug.
