I've installed Knoppix 3.3 19th November to firewire hdd. I'm currently booting using the cd-rom and doing a pivot_root to use my firewire hdd install. Couple of questions:

1. how can I check if the swap is being used? do I have to manuall mnount the swap (which is on the firewire install). 'Top' gives me the idea that at the moment I'm running without swap, a bit worrying as I've only got 128 MB of RAM :(
top - 00:42:01 up 4:21, 1 user, load average: 0.12, 0.14, 0.06
Mem: 126788k total, 121180k used, 5608k free, 12716k buffers
Swap: 0k total, 0k used, 0k free, 47704k cached
2. when I switch ot init 5, the graphical login manager laods up. how can i change it so that I just have a prompt; if I want to have a GUI I prefer to type startx or startkde.

3. how can I change window mangager, are others already installed or do I have to install them?

Got more questions, but I think I've seen most of them discussed elsewhere. I searched for the above, but could not find anything.

Cheers
