I upgraded from 12.04 to 12.10 with no problem. I am trying to edit the grub file, but in console I get the following message:

Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated

As a result I see nothing when the editor opens. Is there a fix for this? I don't see much information on Google about this.

Thanks for any help!
