I’d always gone to the QT 4 Settings from the kickoff launcher.
I should have realised that you had to run qtconfig as root to get it to change for things like YaST!
I now have a nice looking YaST thanks to Droid Sans 9
Sans Serif 9 was a bad choice of font IMHO. I hope it is not the default choice in 11.4!
Glad you managed to change your font
Running 11.4 M3 on my netbook and so far the YaST font looks the same I will fire up the qtconfig utility to confirm
I’d prefer:
kdesu systemsettings
over this Qt4 utility. Let’s you change the appearance of GtK+ applications, in case you have the Gtk+ YaST, that are run as root too.
