grub: highlighted entry blinks in text mode

Bug Description

Binary package hint: grub2

If grub is set to use text mode (GRUB_TERMINAL=console uncommented in /etc/default/grub), the highlighted entry of grub is blinking. This happens because of this line from /etc/grub.d/05_debian_theme:

set menu_color_highlight=black/white

Bright background is not safe to use. The same bit can be interpreted as a blinking attribute. The BIOS default is blinking. I'm seeing it on Toshiba Satellite 1800. Maybe things have changes since then.

To eliminate blinking, following line should be used instead:

set menu_color_highlight=black/light-gray

This bug was fixed in the package grub2 - 1.98~20100128-1ubuntu4

grub2 (1.98~20100128-1ubuntu4) lucid; urgency=low

  [ Colin Watson ]
  * Update DM-RAID probing patch, removing some cruft.
  * Add patch from Colin King to shave eight bytes off the
    pre-partition-table part of boot.img.
  * Don't display "GRUB loading" unless Shift is held down.
  * Use light-gray as the default background for highlighted menu entries;
    white is not safe because some systems interpret the top bit as blink
    (thanks, proski; LP: #527334).
  * Adjust versions of grub-doc and grub-legacy-doc conflicts to tolerate
    our backport of the grub-doc split (LP: #493968).
  * Optimise hostdisk device handling, substantially speeding up grub-probe
    filesystem reads (LP: #425650).
