[raed]

hello guys

i am trying to edit "/boot/grub/menu.lst" to remove quiet splash but when i open konsole - type su - then try kate and kwrite there is error message

Code: [Select]

[b][color=brown][root@localhost raedov]# kwrite /etc/default/grub[/color][/b]
kwrite(3914)/kdeui (kdelibs): Session bus not found
To circumvent this problem try the following command (with Linux and bash)
export $(dbus-launch)

is it a bug ? any idea how can i fix it or how to edit "/boot/grub/menu.lst".

The correct command would be: kdesu kwrite /boot/grub/menu.lst or kdesu kate /boot/grub/menu.lst

export $(dbus-launch)

Do the command as instructed

export $(dbus-launch)

Then launch the application.
