Sometimes when prompted to enter the password to unlock a locked screen the text box has lost the focus. The user must move the mouse pointer and click the textbox in order to enter the password. When this happens the blinking cursor is also absent (even clicking the textbox doesn't show the blinking cursor). I have reproduced it when the screen locker is used with a screen saver. Reproducible: Sometimes Steps to Reproduce: 1. Enable the Screen saver option for the screen locker. 2. Try to lock/unlock the screen couple of times. Actual Results: The screen locks and the unlock dialog is presented as normal. The user must click on the textbox in order for it to take focus and the user be able to enter the password. Expected Results: The text box should not loose focus.
I can confirm this on an Ubuntu system. This is a really annoying bug, when you have to lock your screen several times per day.
I am having the same issue with my self-compiled KDE 4.10.1. The problem is not reproducible: Sometimes when the screen is locked due to inactivity or the system going to suspend, the password field does not have focus. So far, I did not see this happen when using the shortcut to manually lock the screen.
I can also confirm this under Kubuntu. It's quite annoying; sometimes you can just enter your password, and sometimes you can't without clicking first. I haven't found a pattern either, but the password textbox never seems to be in focus for me when waking up from sleep.

Bug 324821 might be related, in a multi-monitor setup, each monitor shows an unlock dialog box, but sometimes no dialog has the keyboard focus.
This can be triggered by pressing the alt key. Looks like the focus is never returned back to the input line after that.
Here's a patch to fix the alt key behaviour: https://git.reviewboard.kde.org/r/113697/ if someone wants to try it out.

The screen locker architecture changed with Plasma 5. The classic screen savers are no longer supported. The 4.x series won't see any further feature development, so this bug report won't be implemented as it doesn't apply to our current version any more. I want to thank you for your bug report and for helping improving the quality of our software and I'm sorry that we were not able to provide a fix before we retired the affected component.
