My aplogies if this message has been sent before, but I've been having trouble with kmail and I'm not sure my last post was sent. Anyway, here we go again - After a crash (one of my regular crashes thanks to my Alcatel DSL USB modem), I find I cannot run Yast2 when I am logged on as myself (not root) and in the KDE environment. I go to the SuSE menu, pick system, pick Yast2 control center. The root password screen comes up. I enter my root password. Nothing happens. I've tried running "kdesu -- yast2 menu" from the command line and I get this: xauth: error in locking authority file /home/kmp/.Xauthority kdesu (kdelibs): WARNING: No X authentication info set for display :0.0 Then the password dialog comes up. I fill in the password and kdesu replies: xauth: error in locking authority file /home/kmp/.Xauthority kdesu (kdelibs): WARNING: No X authentication info set for display :0.0 xauth: error in locking authority file /home/kmp/.Xauthority kdesu (kdelibs): WARNING: No X authentication info set for display :0.0 Then kdesu exits. It seems something is wrong with my .Xauthority file. It exists, but is completely empty. Can anyone tell me what should be in my .Xauthority file? (or is it root's .Xauthority file that's wrong?) Or what these errors mean. Everything worked OK before the crash. I should mention that I get similar errors if I open a shell and type sux then try running yast2 as root. (I get "error in locking authority file /root/.Xauthority then "connection to :0.0 refused by server") - Ken
