Are the x11 100 and 75 dpi fonts absolutely necessary?
If Ubuntu has TrueType support, (as well as OpenType) why do I need all those bit-mapped fonts hanging around?
Can I delete them? (and/or generate ttf/ot versions for those I want to keep)
If I delete those fonts, will some ancient primitive packages still be looking for them and crash, or will I just get a substituted system default?
I've already read this topic: what fonts are absolutely required?
Answers were not really informative enough and kind of vague. I'm hoping my questions are more specific so I get a more definitive idea of just what the font system requires and does not.
