Since last update, I have this message when I login on my kde session: No modules loaded IMsettings won't affects anything on your desktop. please make sure if you have proper module ins.. My rawhide work, and this message disappears after 20 seconds. How do we no longer have this message?
You have to install imsettings-qt for Qt applications for your desktop at least. though you should get the proper backend sub-packages if you do yum groupinstall kde-desktop. How did you install your desktop?
I install imsettings-qt and problem is solved. I install my kde desktop when I installed my F14, option in anaconda "install kde-desktop", and after I update with rawhide repos to get rawhide.
