Comment 3 for bug 1234111

On one of my machines, the problem disappeared and I can normally use the lock screen again. On the other machine, though, there is still no input possibility on the lockscreen and it just shows the background picture without anything else. Killing kscreenlocker_greet from a tty is still the only option. But every now and then when I do this, Xorg dies and takes with it the whole KDE session... This is a very severe bug, I would really appreciate any help to track it down or to fix it.
