[SOLVED]Grub2 HIDDEN MENU not working

Hi there,



i just installed grub2 and edited /etc/default/grub like this:

GRUB_DEFAULT=0
#GRUB_TIMEOUT=5
GRUB_HIDDEN_TIMEOUT=4
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_DISTRIBUTOR="Arch Linux"
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX="quiet loglevel=3 logo.nologo console=tty1 splash=silent,fadein,fadeout,theme:arch-black"
# 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=true

# 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"

but instead of just booting the first entry, grub waits 4 sec and then displays the normal grub menu. What i want is that the grub menu is not displayed at all, unless i press the shift key during that 4 seconds period in GRUB_HIDDEN_TIMEOUT=4. What am i doing wrong?


Thanks in advance,

RobertBuhren


PS: Yes i executed "grub-mkconfig -o /boot/grub/grub.cfg" after each change to /etc/default/grub

Re: [SOLVED]Grub2 HIDDEN MENU not working

set 

GRUB_TIMEOUT=0

The grub2 hiddenmenu first hides the menu for <GRUB_HIDDEN_TIMEOUT> seconds (it displays the hidden timeout countdoen if <GRUB_HIDDEN_TIMEOUT_QUIET> is not enabled)  and then displayes the menu for <GRUB_TIMEOUT> and then boots to the default entry.

Re: [SOLVED]Grub2 HIDDEN MENU not working

Thanks skodabenz for the quick answer. I changed GRUB_TIMEOUT=0 but still it is not quite working the way i wanted. There are still the messages like "Loading Grub" etc. how to i get rid of these? Actually i want my bootloader to print nothing on the screen. It should only by visible when i`m pressing a button during startup. Also with GRUB_TIMEOUT=0 i can`t access the grub menu anymore (i tried pressing the "shift" and the escape button during startup).

Thanks in advance,

You can't stop "Loading GRUB" from disappearing. That message comes even before the grub.cfg is parsed by grub2.

Also with GRUB_TIMEOUT=0 i can`t access the grub menu anymore (i tried pressing the "shift" and the escape button during startup).

For me "Shift" does not work, but "Esc" works. can you post th generated grub.cfg?

Re: [SOLVED]Grub2 HIDDEN MENU not working

In grub.cfg the code should be like

if sleep --interruptible ${GRUB_HIDDEN_TIMEOUT} ; then
  set timeout=${GRUB_TIMEOUT}
fi

In your grub.cfg instead of

if sleep --interruptible 4 ; then
  set timeout=0
fi

it is

if sleep --interruptible 0 ; then
  set timeout=0
fi

I don't know what is the exact cause of this bug though.

I`m now able to enter the grub menu by pressing escape. Although this is not the best solution for me because it adds an unnecessary delay to the boot process (ok 1sek isn`t much but still smile ) Is there a way to get rid of the "echo" statements in the grub.cfg? I think editing the grub.cfg itself is not a good idea.

Robert

You should ask that in grub-devel mailing list or #grub in irc freenode. Anyway for now mark the thread as [SOLVED].
