Mandriva 2010.1 screen and keyboard freeze after login
I have been running Mandriva KDE for some time, quite successfully and have always been able to either upgrade or re-install new versions. Until 2010.1. The upgrade went OK and I logged in, only to have a complete freeze of screen, mouse and keyboard. I rebooted with Alt+PrtScr+B and the same result.
Has anyone else seen anything like this? Any recommendations gratefully received.
