I recently did the KDE upgrade. I did this upgrade through YaST and everything seemed to go fine. All my apps work and everything looks real nice. The problem I have had crop up is that I can't use the ctrl-alt-F7/F8 to switch from one session to the other. I can use the switch option and log in to the new session, but when I try to switch the screen goes black and the cursor just blinks in the upper left corner. When this happens the computer is frozen in this mode. The only option I have is a ctrl-alt-del to reboot. Any ideas?
