[gentoo-user] Strange grub problem

[gentoo-user] Strange grub problem

[Ivan Alden]

Hi,

My laptop ran out of battery and shut off while I was using it and it
seems to have done some damage to the bootloader. When I reboot I can't
see the grub splashscreen any more but if I press enter I does boot into
my kernel. As the computer is booting the output looks all messed up
(but you can make that its initializing devices) until it reaches around
the networking devices which then corrects and works properly.

I've tried reconfiguring grub with
root (hd0,0)
setup (hd0)

Does anybody have any suggestions of how to fix this?

Thanks.

This was discussed over the past day or so.  If I recall correctly the 
splash image has been moved by some package update.  Just check that 
everything your grub boot line points to is actually there.

If you need more info, I can search through my old emails and find the 
fixes for you.

Thanks its fixed. I guess it was coincidence I lost power at the same
time to this issue. I appreciate the help.

Your welcome.  Just a normal reboot would have helped that "issue" come 
out of the dark too.  You are not alone in having that happen.

Glad you got it sorted.

Copy a grub splash image from /usr/share/grub/ or /usr/share/splashimages/ 
back into your /boot/grub/

The last grub upgrade has messed up your settings without asking you - 
unacceptable behaviour for an ebuild.

Maybe it is this grub splashimage problem. If so, see for grub "emerge 
make boot screen and others unreadable" in this mailing list.
If not, I am sorry, don't know an answer.

Hello Ivan,
I had just yesterday exactly the same problem, not because my laptop
runs out of battery, but because of full system update. I do it only
once a week. Anyway.

I could fix it in the following way:
- Switch off your laptop and wait some seconds.
- Start your laptop
- Boot your kernel, you have to imaging on which position in the
  boot menu this one is
- after the machine is up and running
- emerge -av grub
- reboot and it should be fine

That's it.

Hope I could help

Oh sorry,

_very_ _important_ :

Mount your boot partition _before_ you emerge grub.

I believe that the grub ebuild mounts it for you, messes up your grub.conf and 
carries on with its business . . .

So far I that now, is that now changed. You have to mount it before
you emerge grub. The following is from the ebuild grub-0.97-r6.ebuild:

-- Quote begin ---------
pkg_postinst() {
    if [[ -n ${DONT_MOUNT_BOOT} ]]; then
        elog "WARNING: you have DONT_MOUNT_BOOT in effect, so you must
apply"
        elog "the following instructions for your /boot!"
        elog "Neglecting to do so may cause your system to fail to boot!"
        elog
    else
        setup_boot_dir "${ROOT}"/boot
        # Trailing output because if this is run from pkg_postinst, it
gets mixed into
        # the other output.
        einfo ""
    fi
    elog "To interactively install grub files to another device such as
a USB"
    elog "stick, just run the following and specify the directory as
prompted:"
    elog "   emerge --config =${PF}"
    elog "Alternately, you can export GRUB_ALT_INSTALLDIR=/path/to/use
to tell"
    elog "grub where to install in a non-interactive way."

}

-- Quote end ------

Good!  That's the preferred behaviour.  It shouldn't really mess things up 
without asking.

Yeh, you are right, but that seems not always to be true. :-(

It doesn't touch grub.conf, that would be unacceptable. What is does do
is it no longer installs the default splash image to /boot, so that is
removed when the previous version is unmerged. If you use a different
image, or even if you have touched the existing splashimage file, your
boot won't be affected.

[Pintér Tibor]

same here with the latest grub update on x86.
setting the console font restores normal operation during the boot process.
