Now done. ** Description changed:
- 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* + [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. - 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. + [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. - 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. + [Regression Risk] + This SRU only removes a patch added in the previous SRU. ** Changed in: grub2-signed (Ubuntu Artful) Status: New => In Progress ** Changed in: grub2-signed (Ubuntu Bionic) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752767 Title: grub2 regression, simultaneous console and video graphical glitches with new patch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1752767/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
