However, "E233: cannot open display" error appears when starting gvim
on ubuntu 8.04 root shell.
# gvim /etc/fstab
E233: cannot open display
Press ENTER or type command to continue
# kdesudo gvim /etc/fstab
kdesudo: cannot connect to X server

What does 'DISPLAY' say, before and after you run the sudo?

# echo $DISPLAY
# sudo echo $DISPLAY
.
