Some more questions about kde
 

- does kde have a 'force quit' item like gnome? how can i get/create an item like that to hav as panel icon like in gnome? can i get the gnome adding as a non-kde application to the panel? wheres the exec and does it need starting args?

- lisa deamon doesnt run says it needs to be activated by root, ive already set it up in cotrol center but it doesnt run either in user mode as in root mode, how do i "activate" it?

- when i log in as root i always get this starting error message "informational - artsmessage; error initializing the sound driver; device: default can't be opened for playbak (Invalid argument) TRhe sound server will continue, using the null output device" but works fine in user mode.

all for now, sure soon more will come ^^

By force quit, if you mean killing an app then use the kill command and the app PID.
Top will show you whats running and the PID

PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND
591 user 96 0 142M 15800K select 0:10 0.29% 0.29% Xorg
617 user 20 0 62008K 54012K kserel 0:56 0.00% 0.00% firefox-bin
594 user 96 0 5676K 5020K select 0:01 0.00% 0.00% fluxbox
will kill firefox in the example above.

If you want to kill the OS then use the halt command.
To run lisa if it is installed just su to root then type lisa.
enter password
You should not be running a GUI as root, bad idea. If you need root access to a file or process just su to root and run it. Or better yet, set up your sudoers file then a user can run commands as root.
