hELP!? cant get text editor to work as su

[etheesdad]

Hi I want to edit my grub menu.lst file

When I do sudo su and then kate menu.lst

it says

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

cannot open display:
Run 'gedit --help' to see a full list of available command line options.
root@jim-desktop:/boot/grub#

Why is it refusing to open the text editor?

Open a console. Type:

kdesu kate /boot/grub/menu.lst

There's a How-To fix that error somewhere here on the board, I saw it recently (past couple days), but now can't find it. I get that error quite often, too.


If kdesu kate also doesn't go for you, then:

You can re-boot; or first try Control-Alt-Backspace..

You can also just give up and go for GUI, if you can:
Konqueror
Enter /boot in the location window
click on the grub folder
right-click on menu.lst
Actions > Edit as Root
then it opens (as root) in KWrite or in Kate
do your edits
then File > Save and File > Quit
