Re: log in as the root
Hi
You could use the prefix sudo before running commands that need to be run as root, for example:
sudo kate /boot/grub/menu.lst
This will open the file menu.lst, and because of the sudo prefix, give you permission to change and save it.
You could also use the prefix kdesu. I'm not really sure what the difference is, some say it's safer to use kdesu but I've always used sudo and I haven't run in to any problems.
If you're extremely keen on actually being root, you could use sudo -s. This will switch the user to root. To switch back, type su YOUR_USERNAME. -
Re: log in as the root
Always use kdesu when you're going to run a GUI app as root. It's not because "some say" it, but because Ubuntu says you should.

Iwas still able to edit the menu.lst and save it ok
Is this some thing to do with a network it is trying to connect to or do i have a broken link some where?Comment

Re: log in as the root
the right command is
the sudo command is only for terminal commands, not for GUI programs (as jucato already told you)Code:kdesu kate /boot/grub/menu.lst
for example if you edit your file with vi terminal editor, you type
Code:sudo vi /boot/grub/menu.lst

Re: log in as the root
vi is a text editor that runs in a terminal, sorry for my bad explanation
