yast problem

I’m running openSUSE 11.0 and xfce on a older laptop. I’m new to linux.

I was just getting the hang of things when I got a message today about security updates. I installed them, but now YAST will no longer run in graphical mode. When I try to force with yast --qt, I get the error message, “Qt GUI wanted but not found, falling back on ncurses.” Well this has me falling back on a few curses myself. Did the upgrade change a library so now yast is incompatible?

Open a terminal and type
su
root password

now do

zypper dup

if that doesn’t help get back
