Grub theme: black screen with purple border

[Edwin Pujols]

There's a minor typo on the grub theme which produces a black screen with purple border before the grub menu is drawn and on Plymouth start. AIUI, there's a `!` (negation) missing before the background_color invokation:

$ cat /lib/plymouth/themes/ubuntu-logo/ubuntu-logo.grub
  if background_color 44,0,30; then
      clear
  fi

should be

$ cat /lib/plymouth/themes/ubuntu-logo/ubuntu-logo.grub
  if ! background_color 44,0,30; then
      clear
  fi

I don't think this is a bug; the effect of clearing the screen after successfully setting the background_color should, AIUI, be precisely to refresh the screen with the background color (as opposed to only using the background color when drawing more text to the screen). But assigning to Colin, who (as grub maintainer and author of the code in question) will be able to answer more authoritatively.

[Edwin Pujols (edwinpm5)]

OK, I also thought that at first. But when I tried with the "fix", the
purple frame disappeared:

- With timeout=0, the screen was purely black (good)
- With timeout>0, the background was purple under the menu (good)

I'll check again.

[Edwin Pujols (edwinpm5)]

Yep, after testing it again I can confirm the frame is drawn before the grub menu is presented (or when timeout=0). With the negation this does not happen: background is continuous on one or other color, the right thing (tm).

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Alberto Salvia Novella (es20490446e)]

It's a cosmetic or usability issue that doesn't limit the functionality of a non-core package.

[Sebastian (sebastianhaselbeck)]

shouldnt this phase show the ubuntu logo with what used to be a loading bar?

[Sebastian (sebastianhaselbeck)]

Still having this on a fresh install of 14.04
Disappointing. So how can it be fixed? Would be nice to see the regular Ubuntu logo splash screen instead....

[Brian Burns (aundae)]

I also see this on a fresh install of 14.04 today. The proposed fix doesn't change the behavior for me.

[dan (dadan)]

See attached what it looks like. it's a regression since 13.10 --> 14.10 upgrade.

it boots coorectly, but no access to grub menu and its options.

[Aidan (knowles-aidan)]

Also experiencing this bug on fresh install of 14.04.

Grub covered with black square and purple border + no plymouth screen/animation on boot.

[jaideepsai (jaideepsai)]

Hi friends i am a newbie to ubuntu ...i recently made a fresh install of 14.04 ...i have this black +bluescreen problem.....can anyone tell me how to fix it?
Thank you in advance

[Matt White (mattw922)]

Same experience as others here. Proposed solution made the purple frame go away, but still no access to GRUB options.

[Edwin Pujols (edwinpm5)]

I believe this comment might provide a workaround to the "no access to GRUB options" problem:

https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1273764/comments/8

It's about another bug in which grub ignores the timeout options in /etc/default/grub
