 |
|
Hi,
I have upgraded to GRUB2 and managed to get my system to boot but don't see any grub menu. I assume that the system is just falling through to the default kernel after the timeout. I tried uncommenting
| Code: |
GRUB_TERMINAL=console
|
and remaking the grub.cfg:
| Code: |
grub2-mkconfig -o /boot/grub/grub.cfg
|
but no luck.
Here is grub.cfg:
http://pastebin.com/h9BZaTz8
Any clues? |

If you want to see the menu for ever until you make a choice set in /etc/default/grub
| Code: | GRUB_HIDDEN_TIMEOUT=-1
GRUB_TIMEOUT=-1 |
and then
| Code: | | grub2-mkconfig -o /boot/grub/grub.cfg |

I don't see the menu at all. Currently I have
| Code: |
GRUB_TIMEOUT=10
GRUB_HIDDEN_TIMEOUT=0

I've never used grub2, so it's just a guess.... timeout=0 means "show menu for 0 seconds and then boot default"
I'd be surprised if you have noticed menu shown for 0 seconds. Try what Logicien suggested and set it to -1 instead. It's a common trick to use negative value as "infinity" (sometimes 0 means infinity, but as it can be a valid value you need something else) |

I'm hesitant to set the timeout to -1 since I've never actually seen the grub2 menu and wouldn't know how to navigate it blind. I did try setting everything to 60s:
| Code: | GRUB_HIDDEN_TIMEOUT=60
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=60 |
Then rebuilt grub.cfg.
On booting I go through the BIOS screen, then the screen goes blank for approximately 60s before finally booting. I think GRUB2 seems to be handling the timeout time properly just not the video. |

If you want to see what is happening in the 60 seconds while it is loading do this.
In the /etc/default/grub file have this line.
| Code: | | GRUB_TERMINAL=console |
At least I think this is what your talking about.
If you change this file be sure to run the commands.
mount /boot
grub2-mkconfig -o /boot/grub/grub.cfg |

Tryn,
I already have that set. It seems that should disable the graphical menu in favor of a text one but I don't even get the text menu. |

nw_biohazard, I'm not sure but, just in case it gives you an idea, below is my working /etc/default/grub file. I had to add the "GRUB_VIDEO_BACKEND=vbe" to get a background image to be displayed for the GRUB 2 menu, so perhaps you could compare the file below to yours to see if anything else is different that might be worth trying.

Thanks for the suggestion. I tried "GRUB_VIDEO_BACKEND=vbe", both with and without "GRUB_TERMINAL=console" and with "GRUB_GFXPAYLOAD_LINUX=640x480" and "GRUB_GFXPAYLOAD_LINUX=1024x768". Still no luck. I'm posting the entire default file here in case that helps anyone locate the problem.

Could it be something to do with your framebuffer, I wonder? I've got xf86-video-fbdev installed:
| Code: | $ eix xf86-video-fbdev
[I] x11-drivers/xf86-video-fbdev
Available versions: 0.4.3 (~)0.4.3-r1 0.4.4
Installed versions: 0.4.4(19:19:29 31/12/13)
Homepage: http://xorg.freedesktop.org/
Description: video driver for framebuffer device |
and I have the following kernel options selected:
| Code: | $ cat /usr/src/linux/.config | grep -i frame
CONFIG_SCHED_OMIT_FRAME_POINTER=y
# Frame buffer hardware drivers
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=y
CONFIG_FRAMEBUFFER_CONSOLE_ROTATION=y
CONFIG_FRAME_WARN=2048
CONFIG_ARCH_WANT_FRAME_POINTERS=y
CONFIG_FRAME_POINTER=y |

Thanks for the suggestion. I did not have xf86-video-fbdev installed so I emerged it:
| Code: | # emerge --search xf86-video-fbdev
Searching...
[ Results for search key : xf86-video-fbdev ]

My kernel options are nearly identical to yours:
| Code: | # cat /usr/src/linux/.config | grep -i frame
CONFIG_SCHED_OMIT_FRAME_POINTER=y
# Frame buffer hardware drivers
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=y
# CONFIG_FRAMEBUFFER_CONSOLE_ROTATION is not set
CONFIG_FRAME_WARN=2048
CONFIG_ARCH_WANT_FRAME_POINTERS=y
CONFIG_FRAME_POINTER=y
|
Still no luck. By pressing a key at the appropriate time during the blank screen episode, I can tell that the menu is actually there as booting is delayed until I hit a RETURN. Can't see the menu though.
I must misunderstand something about how GRUB works because I don't see why kernel options would matter before the kernal has actually been chosen. |

If you read the GRUB 2 documentation:
| Quote: | ‘GRUB_TIMEOUT’
Boot the default entry this many seconds after the menu is displayed, unless a key is pressed. The default is ‘5’. Set to ‘0’ to boot immediately without displaying the menu, or to ‘-1’ to wait indefinitely.
‘GRUB_HIDDEN_TIMEOUT’
Wait this many seconds for a key to be pressed before displaying the menu. If no key is pressed during that time, display the menu for the number of seconds specified in GRUB_TIMEOUT before booting the default entry. We expect that most people who use GRUB_HIDDEN_TIMEOUT will want to have GRUB_TIMEOUT set to ‘0’ so that the menu is not displayed at all unless a key is pressed. Unset by default.
‘GRUB_HIDDEN_TIMEOUT_QUIET’
In conjunction with ‘GRUB_HIDDEN_TIMEOUT’, set this to ‘true’ to suppress the verbose countdown while waiting for a key to be pressed before displaying the menu. Unset by default. |
I think you need to have:
| Code: | | GRUB_HIDDEN_TIMEOUT=0 |
At the moment you have it set to 10 seconds, the same as GRUB_TIMEOUT. Notice that, in my /etc/default/grub file, I have GRUB_HIDDEN_TIMEOUT=0 and GRUB_TIMEOUT=10.

Thanks. I changed to the following:
| Code: | GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
|
And tried with and without GRUB_TERMINAL=console commented. Same behavior. |

| I know it might be considered giving up, but why won't you just mask grub2 and update to grub1? |

I'm getting close to that point. I would not have upgraded but was persuaded by the dire warnings about grub1 no longer be developed/supported.
I suspect this may be a hardware-specific issue. I need to learn a bit more about how grub2 handles video. |

| Ok, I get the point. Don't worry, you won't get hacked with emac through s/sendmail/grub/. As long as it is usable for you it's perfectly fine, even if nobody tunes it to match new filesystems anymore. What has been done will work until some major changes ocure, and that change would most likely be switch to UEFI. |

I still don't have GRUB2 working but may have made some progress. When booting from a SystemRescueCD flash drive, I get a working (non-graphical) GRUB2 menu. I tried comparing the grub.cfg file from SystemRescueCD with my installed version but can't seem to figure out the relevant difference. Any help at what variables to set in /etc/default/grub to reproduce these settings would be appreciated.
The grub.cfg file from SystemRescueCD is very simple:
| Code: | # Global options
set timeout=90
set default=0
set fallback=1
set pager=1
# Display settings
if loadfont /boot/grub/font.pf2 ; then
set gfxmode=auto
insmod efi_gop
insmod efi_uga
insmod gfxterm
terminal_output gfxterm
fi
menuentry "SystemRescueCd (64bit, default boot options)" {
set gfxpayload=keep
linux /isolinux/rescue64
initrd /isolinux/initram.igz
}
menuentry "SystemRescueCd (64bit, cache all files in memory)" {
set gfxpayload=keep
linux /isolinux/rescue64 docache
initrd /isolinux/initram.igz
}
menuentry "SystemRescueCd (64bit, alternative kernel with default options)" {
set gfxpayload=keep
linux /isolinux/altker64
initrd /isolinux/initram.igz
}
menuentry "SystemRescueCd (64bit, disable Kernel-Mode-Settings)" {
set gfxpayload=keep
linux /isolinux/rescue64 nomodeset
initrd /isolinux/initram.igz
}
menuentry "SystemRescueCd (64bit, directly start the grahical environment)" {
set gfxpayload=keep
linux /isolinux/rescue64 dostartx
initrd /isolinux/initram.igz
}
menuentry "Boot exising Linux OS installed on the disk (64bit kernel)" {
set gfxpayload=keep
linux /isolinux/rescue64 root=auto
initrd /isolinux/initram.igz
}

What kernel are you using? I don't even see that kernel listed in portage that shows in your grub.cfg .
The basic difference that I see between my grub.cfg file and yours is these two items
| Code: | function load_video {
if [ x$feature_all_video_module = xy ]; then
insmod all_video
else
insmod efi_gop
insmod efi_uga
insmod ieee1275_fb
insmod vbe
insmod vga
insmod video_bochs
insmod video_cirrus
fi
} |
Then this line.
| Code: | | set gfxpayload=keep |
The rest of the difference that I see is just the uuid for your items which would be different.
Then the kernel which I can't find in portage.
I'm using this one. sys-kernel/gentoo-sources-3.12.13 |

Kernel:
| Code: | # uname -a
Linux wombat 3.2.1-gentoo-r2 #9 SMP Sat Feb 16 15:16:57 PST 2013 x86_64 Intel(R) Core(TM) i5-2405S CPU @ 2.50GHz GenuineIntel GNU/Linux
|
Why would the kernel version matter? I thought that GRUB functioned before any specific kernel was loaded? |

Here is my working /etc/default/grub file. This file is taken from a newly installed gentoo laptop and is exactly what I got after installing grub2 as shown in the installation handbook.
I am not a grub2 expert at all, but I cannot believe that the kernel configuration make any difference at all.
Just to confirm... When you run the grub2-mkconfig command, it your /boot filesystem mounted? iirc, be default the gentoo /etc/fstab does not mount /boot automatically.
After updating your /etc/default/grub file, make sure /boot is mounted, run the grub2-mkconfig and then to a full power down reboot (shutdown -h now). I read somewhere in the forums that there was the possibility of memory artifacts left in memory for a shutdown -r now reboot. That seems pretty far fetched to me, but it is worth a try.

Thanks for the advice. I have verified that /boot is mounted and that a new grub.cfg file is created each time. I tried the shutdown -h now followed by a reboot with the same result.
I strongly suspect this is some sort of video mode issue. I'm trying to understand whether, in the working grub.cfg file, the following lines are executed:
| Code: | # Display settings
if loadfont /boot/grub/font.pf2 ; then
set gfxmode=auto
insmod efi_gop
insmod efi_uga
insmod gfxterm
terminal_output gfxterm
fi |
Not sure how I can tell if the "loadfont" variable is set.
If not, then it seems that everything is being determined by
| Code: | | set gfxpayload=keep |

Update after another read of the GRUB manual, more hacking with numerous combinations of parameters in /etc/default/grub, and testing a couple of different keyboards. No combination of parameters I have tried so far has caused the grub menu to appear.
As far as I can tell, grub is responding correctly to the setting of
Setting it to some positive number causes the system to wait that long unless a carriage return is entered to launch the default entry. Setting it to 0 causes immediate boot of the default. Setting it to -1 causes grub to wait for a carriage return.
Setting
| Code: | | GRUB_HIDDEN_TIMEOUT |
to a negative number does not seem to have any effect.
Setting
| Code: | | GRUB_TERMINAL=console |
also has no effect.
I also tried commenting everything out of /etc/default/grub and running
| Code: | | grub2-mkconfig -o /boot/grub/grub.cfg |
with no effect.
I suspect this might be a hardware issue. I'm running an ASUS P8H67-M motherboard with integrated Intel Integrated Graphics Processor. If anyone has a working grub2 configuration for a similar system, it would be great to see it.
Here is my current /etc/grub/default

I've examined the grub2 setup on a version of SystemRescueCD which displays the menu when I bood from a USB flash drive and tried to transfer that grub.cfg to the my Gentoo system. Here is the SystemRescueCD grub.cfg file, modified for my system:
| Code: | # Global options
set timeout=90
set default=0
set fallback=1
set pager=1
# Display settings
if loadfont /boot/grub/font.pf2 ; then
set gfxmode=auto
insmod efi_gop
insmod efi_uga
insmod gfxterm
terminal_output gfxterm
fi
menuentry "Gentoo GNU/Linux" {
set gfxpayload=keep
linux /kernel-3.2.1-gentoo-r2 root=/dev/sda3 ro
}
|
I also copied /boot/grub/font.pf2 from the SystemRescueCD installation to /boot/grub on my machine.
Unfortunately, this grub.cfg behaves exactly as all of the ones I have generated on my system: no menu is ever displayed regardless of whether <SHIFT> (have tried both left and right) or <ESC> is pressed, or any other variable setting in /etc/default/grub that I have tried.
It seems that there must be some difference in the environment on boot between the SystemRescueCD installation and what I have that is causing something not to get picked up by grub but I have no clue what that might be.
One thing that does seem somewhat different is the presence of "efi.img" and "x86_64-efi" in /boot/grub. Not sure what the significance of that is but any help would be appreciated as I am rather hamstrung at the moment in terms of rebuilding or upgrading kernels if I can't choose them in the grub menu. Thanks in advance!
