I upgraded from 12.04 to 12.10 with no problem. I am trying to edit the grub file, but in the 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 can't find much information on Google.
