Did a fresh "install" (copy to SD-card and boot) of


on a Raspi 3.

Working fine, but when I try to open Yast in GUI (XFCE via VNC, as a normal user, not root), I'm asked for the root password, but afterwards nothing happenz. If I open a console, do a "su" and enter Yast, I can do config changes etc., but that's not as convenient as in the graphical version.

Tried before and after "zypper dup".

Might it be that Yast is blocked in the GUI because of VNC connection? (Have no monitor to test direct access). If the answer is "yes" or "possible", is there any way to change the security settings to allow Yast via VNC?

Many thanks in advance!
