    How to edit Grub 2.0 boot loader time out.

    So the time out is default at 10 seconds, I want it to be 300 seconds. Sudo /etc/default/grub and bring it up and edit it, but as soon as I type anything it changes to read only and wont save. Do I need to save it as a new file? If so which one?

    You need root privileges to edit and save this file.
    Also, dont forget to call "update-grub" afterwards.
    You must always face the curtain with a bow.

    If you're using the command line such as vi, sudo should work fine.
    If you're editing the file in GUI mode, use gksudo gedit /etc/default/grub
    After saving the file, you want to run grub-mkconfig -o /boot/grub/grub.cfg
