when i boot into knoppix using GRUB (finally it works) :

title Knoppix 3.2
root (hd0,4)
kernel /boot/vmlinuz-2.4.20-xfs root=/dev/hda5
initrd /boot/initrd.gz

and now i'm stuck with the command line (eg: knoppix@Mark:#$)
or something like that.. so how do i get to the graphical interface? to knoppix...
