Vaio + Kubuntu?

Hejsan

Jag har precis installerat Kubuntu på min nya sony vaio. Jag postade ett meddelande på ett engelsktalande forum, och jag tänkte klistra in den texten rakt av utifall det finns någon som är engelsktalande som skulle läsa det här

I'll post all of my questions, and I appreciate any help I can get with any of them:

1) How do I get my WiFi to work? I've googled and really tried, but I just can't figure it out. All the pages I've read have been discussing what to do if the WiFi doesn't work at all, but the thing is that Kubuntu sees the WiFi card, and I'm even able to scan the area for networks. I just can't connect to a network, not even the ones without a key. I've tried Network Manager, but I haven't gotten it to work. It seems that NM is meant for Gnome, and I use KDE.

2) How do I know if Kubuntu understands that I have a Dual Core processor? If it doesn't, how do i fix this?

3) How do I get the "fn" and "S1" and "S2" keys to work?

4) How do I do to make the Stamina/Speed switch to work?

5) How do I know that I get the most out of my nVidia graphics card? Is there a test-program?

6) How do I activate Sony Vaio under System Settings / Laptops & Power / sony vaio laptop?

7) I've installed javac, but what should I do to be able to write just "javac" in order to use the java compiler (right now I have to write /home/alex/jdk1.5.0_08/bin/javac. I think I have to change/add a path somewhere, but where and how?)

Cool How do I remove "tapping counts as click" on the pad?

9) How should I approach the problem of drivers when connecting a new device? For example, I've just bought a scanner/printer (Canon PIXMA MP500) and I can't get it to work with my laptop.

10) Once I get the wireless to work, how do get the WIRELESS ON/OFF switch to function?

Here is the computer I've bought:

Well, that's about it for now. I just spewed out all the questions I had (of course I've googled all of them quite a lot). And as I said before, I really appreciate all the help I can get with any of the above questions.

Thanks a lot!
