[SOLVED] Setting Grub timeout?

[robertdaleweir]

Hi
I want to reduce the visible time for grub menu at startup. I cp /etc/default/grub /etc/default/grub-bk . Then I revised /etc/default/grub to the following:
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR="Fedora"
GRUB_DEFAULT=saved
GRUB_CMDLINE_LINUX="rd.md=0 rd.lvm=0 rd.dm=0 KEYTABLE=us quiet SYSFONT=latarcyrheb-sun16 rhgb rd.luks=0 LANG=en_US.UTF-8"

I thought this would change it at boot time but it doesn't seem to work. Any help would be much appreciated...

With grub2, just changing the settings the way you did doesn't make the changes take effect. You need to run this command as root to make that happen:

grub2-mkconfig -o /boot/grub2/grub.conf

I'd also like to point out that taking the timeout period all the way down to zero is a Very Bad Idea because it makes it impossible for you to select an older kernel if the newest one doesn't boot, or to edit the kernel line if you ever need to. IIRC the default is five, but if you're in a hurry, you can always hit Enter to start booting Right Now.

edit the value for set timeout in /boot/grub2/grub.cfg and do grub2-mkconfig -o /boot/grub2/grub.cfg.

Good luck.

Hi sidebrnz
Yes I agree with you about the shorter timeout. Thank you for command:
grub2-mkconfig -o /boot/grub2/grub.conf It is very hard to keep up with all these settings and I very much appreciate your reply...

Hi nonamedotc
Love your username Thanks for your help on this one, I also have /boot/grub2/grub.cfg on my F16 OS. Nice attention to detail, have a great day...

Totally wrong advice. There is no "grub2.conf" file, for you, or anyone else. If you edit the "/boot/grub2/grub.cfg file directly, then do "grub2-mkconfig -o /boot/grub2/grub.cfg", whatever setting is in /etc/default/grub will overwrite your edit in /boot/grub2/grub.cfg.

You make your grub configuration changes in /etc/default/grub, then use "grub2-mkconfig -o /boot/grub2/grub.cfg" to make those changes appear in the /boot/grub2/grub.cfg file.

If you want to make direct edits to /boot/grub2/grub.cfg, then refrain from ever using the grub2-mkconfig command again.

BASH:~/-> grep TIME /etc/default/grub
GRUB_TIMEOUT=10
BASH:~/-> sudo grep time /boot/grub2/grub.cfg
set timeout=10

Thanks for pointing that out PabloTwo. Apologies. I have edited the wrong part so that no one follows that.
