On Ubuntu 23, I want to disable grub pause (the default for 30s) completely = I want 0s. Yes, I am sure. No, I do not have other OSes. I edit file:
sudo nano /etc/default/grub
Contains
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT=0 #new
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
And update settings
sudo update-grub
But nothing helps for my Ubuntu 23. I have UEFI and no secure boot. I also try all variants of GRUB_TIMEOUT_STYLE (menu, countdown, hidden)... How to achieve 0s timeout, please?
Update. I try @vlastimil-burián without success... In my Xubuntu 6.2.0-39-generic I have default very long grub timeout...
My default /etc/default/grub file is
GRUB_DEFAULT=0
GRUB_TIMEOUT_GRUB_HIDDEN_TIMEOUTSTYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
Now I try
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
then
sudo update-grub
After reboot I see default very long delay again... How to disable grub timeout completely?
