So, I don't know what I did (I was tweaking with some configs on my system), but now the fonts on my computer is pixelated I and just can't fix this. I searched about that but didn't found anything useful, like a config file to edit, or something like that.
I created a new user to see if this is my fault, and it was. Anyone here now something that is related with the font rendering? I really need it to read and do some design stuff
(also, sorry for my english)
