giving command as sudo doesn't work

[outer]

Hi all.
I am new to Kubuntu, i'm coming from ubuntu and i have to ask you something cause it seems very strange to me.
I'm used to log as root in order to do some action and hence via terminal i give
sudo su
or
sudo -i
or
sudo command bla bla bla

Now comes the strange thing:

root@lorenzo-desktop:/tmp/vmware-root# bluefish modconfig-4880.log 
No protocol specified
No protocol specified

** (bluefish:7552): ERROR **: Error parsing command line options. Cannot open display: 
Please run: bluefish -?

Rilevato trace/breakpoint (core dump creato)

also kate give such an error and every program i try to run when i am root!

How come? how can i solve this issue? can you help me? thanks for help!!!

You should use kdesudo to run a gui program as root.
