Update problems I don't master

So I took a look at my packages and saw that there were updates to TDE (from 14.0.0 to 14.0.3, openSUSE here). I first choose "update if newer" for all my packages (in Yast) and ended in a disaster: apparently minimal X with a terminal, message about wrong permissions for Xorg. Setting these permissions right let me start X... but only in KDE 4! I thought the problem was with openSUSE, so I restored and tried updating only Trinity. This time the message is: .servauth.1668 does not exist cannot open /var/log/xorg.1.log please consult X.org foundation support There are plenty of lines with (EE) too Same correction to Xorg now brings up Icevm. I'm out of my depth here. I restored again and will make a copy install to investigate the matter. I understand this may be openSUSE linked but any suggestion can help. Not urgent however, 14.0.0 is running very well... Thierry
