I'm not sure when this occured, probably somewhere during the 4.1.2 and 4.1.3 releases of KDE.

The problem is that I have no anti-aliasing of fonts when running KDM, or something which requires root access (KSystemLog). Curiously, an application like Synaptic uses proper anti-aliasing (but not the gtk-qt-kde4 style I assigned, it incorrectly uses Qtcurve instead). All checkboxes regarding anti-aliasing are ticked (in Appearance and Login manager) when I run System Settings both as normal user and as root.

Does anybody know which other settings I might need to change in order to get proper anti-aliased fonts?

I still have this problem with the KDE 4.2 beta.

Anti aliased/hinted fonts do not display in some applications, most notably KDM. But now my KDM also uses QtCurve instead of the native KDE 4/Qt 4 style which was in place before. I think its got something to do with which user (root, nobody, etc.) is running the application.

Does anybody know which config files I need to edit to get the right style and font rendering across applications/users?
