[Bug 1298476] Re: Trusty: inconsistent behaviour of GRUB_TIMEOUT_STYLE=countdown

Fri Mar 28 11:22:30 UTC 2014

After further investigation I found that the problem appears to be
related to installing with LVM enabled. When I installed Trusty I
encountered a problem (that started in 13.10 sometime between 11/28/13
and 1/19/14) when installing with LVM enabled over a  previous LVM
enabled installation (also happens if you try to install with LVM
enabled over a previous Windows 7 installation). This causes a warning
message that the "boot partition is not large enough and the
installation may fail". On the first three machines I did not install
with LVM enabled but on the other four machines I installed with LVM. I
normally install with LVM and had no issues until this warning message
started sometime between 11/28/13 and 1/19/14 (in saucy 13.10).  For
some reason the LVM equipped machines are the ones that are showing the
menu instead of the countdown. I proved this by reinstalling Trusty on
the four machines that were displaying the menu without LVM this time
and they now work as intended. I will attach both a pass (e.g. working
countdown case: sabertooth-nonlvm-grub.cfg) as well as a failure case
(e.g. menu instead of countdown: m4a785m-lvm-grub.cfg) files.

If you need me to reinstall with LVM and collect more data let me know .

Thanks again,
B.Bogert

Title:
  Trusty: inconsistent behaviour of GRUB_TIMEOUT_STYLE=countdown

Status in “grub2” package in Ubuntu:
  New

Bug description:
  For some reason GRUB_TIMEOUT_STYLE=countdown is not being treated in a
  consistant manner on all my machines. On ASUS m4a785m(2), ASUS
  m5a97(1) and ASUS p8h61m despite having the GRUB_TIMEOUT_STYLE set to
  countdown and GRUB_TIMEOUT set to 10 in /etc/default/grub I was
  getting a menu. On ASUS Sabertooth, ASUS a88xpro and another ASUS
  m5a97 countdown worked as designed. After a bit of trouble shooting I
  found that the /boot/grub/grub.cfg files on the offending hardware
  were actually setting the GRUB_TIMEOUT_STYLE value to menu in a OS-
  PROBER block at the end of the file despite it being set to countdown
  in the /etc/default/grub file. Since the offending code was in an OS-
  PROBER block I tried setting GRUB_DISABLE_OS_PROBER to TRUE and
  running update-grub which corrected the problem. Although this
  temporarily fixes the problem I do not think it is addressing the real
  issue which is the inconsistent setting of GRUB_TIMEOUT_STYLE and
  therefor inconsistant behavior even on different machines of the same
  hardware. Since ASUS m5a97(2 different machines) exibited both the
  fail and pass mode I have to think that this is not hardware specific
  but possibly something going haywire in grub_mkconfig. Here is my
  /etc/default/grub file with the problem:

  # If you change this file, run 'update-grub' afterwards to update
  # /boot/grub/grub.cfg.
  # For full documentation of the options in this file, see:
  #   info -f grub -n 'Simple configuration'

  GRUB_DEFAULT=0
  GRUB_TIMEOUT=10
  GRUB_TIMEOUT_STYLE=countdown

  GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`

  GRUB_CMDLINE_LINUX=""

  Here is the "working" /etc/default/grub file:

  # /boot/grub/grub.cfg.
  # For full documentation of the options in this file, see:
  #   info -f grub -n 'Simple configuration'

  GRUB_DEFAULT=0
  GRUB_TIMEOUT=10
  GRUB_TIMEOUT_STYLE=countdown
  GRUB_DISABLE_OS_PROBER=true

  GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
  GRUB_CMDLINE_LINUX=""

  # Uncomment to enable BadRAM filtering, modify to suit your needs

  GRUB_BACKGROUND="/usr/share/backgrounds/warty-final-ubuntu-bt.png"

  Note that the only difference is the GRUB_DISABLE_OS_PROBER=true
  directive.

  I can try and recreate the problem and provide /boot/grub/grub.cfg
  files if needed.

  lsb-release -rd:

  Description:	Ubuntu Trusty Tahr (development branch)
  Release:	14.04 

  Grub version is 2.02~beta2-7,

  Almost forgot.. I upgraded 10 machines (9 desktop and 1 laptop) to Ubuntu 12.04.4 last night and set them up to use GRUB_TIMEOUT_STYLE=countdown. All 10 machines worked as expected without any issue (a mixture of MSI and ASUS
  hardware) so the problem seems to be related to Trusty(e.g. 14.04) only.

  Thanks,
