description |
Okay, so the following patch at http://launchpadlibrarian.net/356413428/grub2_2.02~beta3-4ubuntu7.1_2.02~beta3-4ubuntu7.2.diff.gz
which basically amounts to changing a single line in /etc/grub.d/00_header TOTALLY breaks my menu selection graphics when I boot up. Every time a line changes, like as in scrolling the menu or watching the countdown timer, I can see the console mode GRUB line flashing black and white behind the video gfx mode screen. I believe this regression is caused entirely by Dann Frazier's idea for the grub patch: "Instead of switching from "console" to "gfxterm", let's output to both." *sigh*
Removing the single change, the "--append" flag, in the file /etc/grub.d/00_header and regenerating the grub.cfg file completely solves the problem. What concerns me is that this patch somewhat breaks the average user's default grub gfx mode; it looks glitchy and horrible. I simply cannot tolerate this behavior on an incredibly simple boot selection menu, let alone on an actual grub theme, KDE-style. My machine is a very standard HP EliteDesk 800 G3 Mini Desktop, and I had no problems before with GRUB doing this horrible-looking pop-from-behind simultaneous video and console behavior. This tiny patch represents a misguided and frankly appalling regression.
And yes, this applies upstream to Bionic Beaver (I tried the proposed package also) as well as the current version of the grub2 package on Artful Aardvark. Please fix before the Ubuntu LTS release ships with this glaring bug. |
[Impact]
The last SRU introduced a regression whereby, on EFI systems that support the graphical GRUB menu, there is a flickering affect where the menu switches between graphical and console modes while scrolling through menus.
[Test Case]
On an EFI system that supports a graphical GRUB menu, drop to the edit screen, and hold down the up/down arrow keys to cause rapid scrolling. You should not see the menu switch between graphical and console mode.
[Regression Risk]
This SRU only removes a patch added in the previous SRU. |
