i just went in and deleted the fonts i installed
that worked and i got my pc working
after a while...
i tried this: sudo fc-cache -fv right after i opened nautilus, made a myfonts folder in the truetypefonts and copied all my fonts.
but the result was the same, so i had to remove them manually from root, for the ubuntu to work again.
is there any other way except nautilus for fonts to be installed?
this is obviously not working for me
p.s. i tried at a friends place on fresh 7.10, it did the same crash....no menu, only wallpaper
