According to the default /etc/fonts/fonts.conf, it should not be changed. However, the KDE Font Installer KControl applet replaces this file. The replacement file also breaks Xft-only fixed width fonts (they are 2x wider than they should be).
Correction: The problem with the fixed width fonts does not seem to be related to the replacement of /etc/fonts/fonts.conf. I just didn't notice it since Konsole used a working font with the correct fonts.conf.
I'll be looking into changing this applet, so it uses local.conf. For now, don't use it ;-)
This bug has been inactive for a very long time, probably more than a year. I cant reproduce this. The applet changed my local.conf file, but didn't touch my fonts.conf file. Can this be closed?
Confirmed, in that I can't get it to modify local.conf either, even in admin mode. AFAICS it only modifies the Fontmap file.
Why did you mark the bug as FIXED if you simply confirmed that the bug exists??
Sorry, I thought one thing and wrote another... I meant: I can't get it to modify neither fonts.conf nor local.conf. The only file it ever modifies under /etc/fonts is Fontmap. Other changes go into ~/.fonts (normal mode) or /usr/local/share/fonts (admin mode). The kfontinst changelog corroborates this, and its source never touches/opens fonts.conf or local.conf.
