keyboard doesn't work after xscreensaver shuts down the monitor

[Václav Haisman]

I am experiencing the same symptoms as described in https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/586528. This bug report is new on request.

I run Xubuntu with XFCE, xscreensaver and Light Locker. Recently, whenever I log back (twice, once through locker and once through xscreensaver), the X11 applications are not accepting keyboard input. I can switch desktops using keyboard shortcuts, though. What fixes the issue for me is switching into a Terminal window. Then the keyboard input start working.

I have one more bit of information to add. I have just logged in and clicked into and Emacs X11 window. The cursor in Emacs moved to the place I have clicked onto but it stayed unfilled which means the Emacs X11 window does not have focus. So, it seems like this whole issue has something to do with focus.

Does any of the following actions make the bug to stop?:
- Switch to a non terminal window.
- Pressing the Alt + Tab key combination.
- Minimizing and maximizing the application.

Does locking the screen (Ctrl+L) make the bug to appear?
