[SOLVED] Updates to /etc/default/grub not working

samrob85 · 2017-07-24 14:47:47

My bootloader is GRUB

I am trying to remove the screen to select arch linux on boot to improve boot speeds. I have tried to do this using the following wiki page https://wiki.archlinux.org/index.php/GR … and_tricks. I have modified the file accordingly so it now looks like this:

 
GRUB_DEFAULT=0
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""

# Preload both GPT and MBR modules so that they are not missed
GRUB_PRELOAD_MODULES="part_gpt part_msdos"

# Uncomment to enable Hidden Menu, and optionally hide the timeout count
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=false

# Uncomment to use basic console
GRUB_TERMINAL_INPUT=console

# Uncomment to disable graphical terminal
#GRUB_TERMINAL_OUTPUT=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=auto

# Uncomment to allow the kernel use the same resolution used by grub
GRUB_GFXPAYLOAD_LINUX=keep

# Uncomment if you want GRUB to pass to the Linux kernel the old parameter 
# format "root=/dev/xxx" instead of "root=/dev/disk/by-uuid/xxx" 
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
GRUB_DISABLE_RECOVERY=true

# Uncomment and set to the desired menu colors.  Used by normal and wallpaper 
# modes only.  Entries specified as foreground/background.
#GRUB_COLOR_NORMAL="light-blue/black"
#GRUB_COLOR_HIGHLIGHT="light-cyan/blue"

# Uncomment one of them for the gfx desired, a image background or a gfxtheme
#GRUB_BACKGROUND="/path/to/wallpaper"
#GRUB_THEME="/path/to/gfxtheme"

# Uncomment to get a beep at GRUB start
#GRUB_INIT_TUNE="480 440 1"

#GRUB_SAVEDEFAULT="true"

I then ran grub-mkconfig -o /boot/grub/grub.cfg to apply the changes according to this wiki page: https://wiki.archlinux.org/index.php/GRUB#Configuration

What am I doing wrong?

That gave the same result as before, leaving the menu on for 10s

Were the changes actually applied to /boot/grub/grub.cfg?

You should post that file as well as /etc/default/grub

Presuming that grub.cfg was indeed altered then perhaps the Arch system is not in "control" of GRUB (ie, the bootloader is reading grub.cfg from another filesystem tree on your drive) — are you multibooting?

If so, gain control of GRUB from Arch by using `grub-install`, as per the wiki (or alter grub.cfg in the other system).

Using grub-install says that It can't find the EFI directory

You're supposed to declare the folder under which the EFI system partition is mounted rather than /dev/whatever

The command will need to be run whilst booted in UEFI mode to create a new NVRAM entry.

You seem to be booting with systemd-boot at the moment, which would explain why /etc/default/grub "isn't working"...

You need to use the mount point, not the device name...

grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=grub

Sorry, I tried for a few hours to solve my problem using the wiki and searching the forums but I didn't find anything to say that I was in the wrong boot mode. I will try harder in the future, I've only had Arch Linux for 1 day so am not very experienced in using it but hopefully, with time, I will develop my knowledge and skills.
