I have installed grub-customizer in my system, Kubuntu 14.04.

When I try to start it, I get the following error, (kindly help)...

santosh@santosh-pc:/usr/bin$ sudo ./grub-customizer 
No protocol specified

** (grub-customizer:2992): WARNING **: Could not open X display
No protocol specified
error: XDG_RUNTIME_DIR not set in the environment.

To open grub-customizer simply type sudo grub-customizer in terminal and don't use ./ before that command.

  • try in terminal: gksu grub-customizer – Sudheer May 12 '14 at 17:32
  • I get the message,

    'The program 'gksu' is currently not installed. You can install it by typing: sudo apt-get install gksu.'

    Sorry, for asking a silly question, but is gksu different than sudo. What are the advantages of using it, in place of sudo.

  • you can try installing gksu and run that command again or you may find some info here http://kparal.wordpress.com/2013/02/17/how-to-run-graphical-applications-with-sudo/ – Sudheer May 12 '14 at 17:38

Run

where localuser is Your username. After that, i was able to run

sudo grub-customizer
