Strange KDE2.1 Artifact

Hi, I have installed KDE 2.1 on SuSE 7.0, on both x86 Pro and PPC version. I have downloaded RPMs from SuSE ftp server and installed with YAST. However, I noticed strange keyboard artifact on BOTH systems: function and arrow keys stopped working in terminal window, and now I cannot do anything in YaST1. On the PPC, situation is even worth: after switching keyboard layout all keys are malfunctioning, and screen fonts become garbage. Complete removal and installation of KDE 2.1 did not helped. Thanks in advance for any suggestions. Andrei
