in advance

Been meaining to get into Linux for years now. I have Mr Linux Box No1 up and running on Ubuntu and have even got over the annoyance of having to /sudo everything for root. MY Difficulty is I have a couple of specific things I am looking for solutions for and I can't seem to find help.

Would you mind if I linked a couple of questions I had in other forums here and see if I could maybe get a couple of links to help me out? One question is regarding OpenGL/Quake4 and the second one to do with VPN implementation (or extreme lack of GUI/config for same) in linux. I have been reading every howto I can and googling myself until my fingers are near bleeding (this is worse than guitar).

Here are the 2 links:

For the reply to this, maybe people could just post links for me to look at? I am really looking for sources of help

I've been reading through so so many howto's and I think the biggest barrier is structure of linux, especially directory structure. Like, for example, why is the network ppp stuff stored in etc? WTF is there a dir called etc for and why should it have important and not "etc" type info in it?

Thanks for any help you can provide, and I apologise for the nature of the post as I know it's going to annoy some folks - but I just can't find answers at present
