OpenSuse 13.1 x64, KDE 4.12, problem resume after hibernation


I have OpenSuse 13.1 x64 with KDE 4.12, I have a problem with my laptop after it goes in hibernation, when I try to resume, the connection screen appears without the password prompt window, hit space bar, hit other keys, nothing appears.
I still can connect with shell using the other ttys (ctrl+alt+F1…), but I cannot re-login to my previous KDE session.

any ideas?

thanks in advance.
