[Test case] This will work only in the case that your lockscreen is set (from unity control center, lock pane) to lock immediately (when screen turns off). 1. Open a window that will hold the grab, such as the ssh password dialog or a virtual machine (such as virtualbox in fullscreen). 2. Wait for the lock screen to activate [1]. 3. The screen won't be locked, since it's not possible to steal drag to another window. [Regression potential] For the same reason of lp:49579, we can't lock the screen (yet) if something takes the grab in X, or we won't able to get input back. This is not a regression because it has never been possible in Ubuntu before, while when we tried that, it caused this bug. A possible source of regression might be that we now try to grab/ungrab the screen (the only X reliable way for grab checking), when showing the dash/hud or the lockscreen itself, and this might slow things down a little, but from measurements done this slow down is generally about 2ms, so nothing to worry about. * Compiz Debdiff is found at https://launchpadlibrarian.net/178439518/compiz-trusty-sru-2.debdiff * [1] You can use this to reduce the locking delay: gsettings set org.gnome.desktop.session idle-delay 5 and resetting it with: gsettings reset org.gnome.desktop.session idle-delay ----------- Original Description: My screen just timed out and locked when a password prompt which had a grab was displaying. I couldn't type my password or interact with the indicators. gnome-screensaver just refuses to lock in this situation, perhaps unity could do the same unless it's possible to remove and readd the grabs yourself, but I don't think XLib lets you do that (you can only remove your own grabs AFAIK).
