Whoops... I may have my desktop back, but I CANNOT access another login screen.... errr.. terminal, using ctrl alt +Fx key, all I get is nothing... no video at all, the only F key that works is F8 for the KDE session.. I had this problem when I was trying to rename my .kde4old... I couldn't log into another terminal to do it, so I had to use a terminal in the kde session. The desktop is back to normal but the other terminals are still missing.
