@Andreas , @Martin - let me clarify, I'm having the issue brought up by the patch that Lorenzo reports, With "file:///usr/share/plasma/look-and-feel/org.openSUSE.desktop/contents/lockscreen/MainBlock.qml:85: TypeError: Property 'tryUnlock' of object function() { [code] } is not a function" I note that it takes a little while after the monitor is turned off - and by turned off, I mean monitor suspend makes it happen. If you still wish for me to file the bug at bugs.kde.org, will do so but I just wanted to make sure we weren't too suse specific since there's this patch mentioned in this thread.
