Basic questions

[Rafi Gabzu]

Hi ,
I just installed Debian "testing" , I'm new in Linux. Few questions:
1. How do I configure my audio card , it doesn't recognize it ?
2. How do I add additional keyboard layout (Hebrew) and fonts?
3. How do I know if I'm working in KDE /GNOME , how do I switch between them ?
4. Is there a guide/book that can help new users like myself ?
I have many more questions ...

Thanks,
