fc-cache command gives me this error
Fontconfig error: Cannot load default config file
Reinstalling fontconfig solves both this error message and the problem with the fonts of the login manager.
However the fonts after login looks horrible. Changing settings in system settings and even in the preferences of the internet browsers has no effect.
I remember that I followed the instrutions of the link below to improve the font rendering a few days after install my system, maybe it’s a cause of my problems.
Can anyone say how to undo the following symbolic links please?
sudo ln -s /etc/fonts/conf.avail/70-no-bitmaps.conf /etc/fonts/conf.d
sudo ln -s /etc/fonts/conf.avail/10-sub-pixel-rgb.conf /etc/fonts/conf.d
sudo ln -s /etc/fonts/conf.avail/11-lcdfilter-default.conf /etc/fonts/conf.d
