How do I change the grub menu boot time to say 10 seconds?
I’m using Fedora Silverblue

Thanks

Not sure what editor to use but the file is /etc/default/grub. Probably need to use the sudo command as well for access.

Anyway I was able to see the contents of that file without using sudo. Went to /etc/default and just did a cat grub command and the contents of the file appeared.

Command not found was the reply. But was able to make it work with this code.
sudo nano /boot/grub2/user.cfg
set timeout=10
Ctrl S - to save and reboot

Thanks

Interesting. I was able to do a sudo nano /etc/default/grub and then changed my timeout from 5 to 10 and it worked. Glad you figured out a different method as well. Sometimes in Linux there are a couple different ways to do things. Don’t know if me being on MATE would have anything to do with that. It would seem that the base commands would be the same.

If you want to make your code stand out when you post it just select it and then hit the </> button at the top of the edit screen. Just an FYI.

Well, I learn something every day. From a Google search I found this previous thread on the same forum here and figured out how to update grub by reading the very first post. Linux is pretty simple really. Don’t be afraid of the command line…

The Atomic Desktops (Silverblue etc) use a static GRUB config file at /boot/grub2/user.cfg, whereas in non-atomic Fedoras, the defaults are at /etc/default/grub and are incorporated into the config when grub2-mkconfig is run.

So you and @usfarang both did the right thing for your own flavours of Fedora, but it’s not interchangeable between atomic and non-atomic.

Thank you for that information. Good to know.
