Changing Grub2 settings have no effect

n0rv · 2012-11-06 18:45:41

I try to set higher resolution and swap partition for resuming from hibernation. My Grub config looks like this:
/etc/default/grub

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vga=775"
GRUB_CMDLINE_LINUX="resume=/dev/sda7"

# 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=5
#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=1280x1024x8

# 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"

After running:

grub-mkconfig -o /boot/grub/grub.cfg

as root I have:
/boot/grub/grub.cfg

#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by grub-mkconfig using templates

After reboot I need to manually edit options in Grub menu, because this config takes no effect. I have something similar to:

.linux /vmlinuz-linux root=UUID=2dfb055e-f6e5-41f6-846e-0ab29d67178a ro quiet

I missed something? I tried everything from wiki: https://wiki.archlinux.org/index.php/Gr … resolution and nothing.
I have Radeon hd4770, fglrx driver (12.6) from AUR, kernel 3.6.6-1

Any suggestions?

Do you have a separate /boot partition that you're either mounting or forgetting to mount? Or perhaps another Linux distribution?

Yes, I have separate /boot partition, but it's not a problem (I think), because Grub boots kernel properly (I write this post from Arch).
It looks like Grub can't read config and loads kernel with default options.

Maybe, but I'd like to make sure.

Can you post the output of:

uname -a

and

file /boot/vmlinuz-linux

uname -a
