Hi Sebastien, thank you for looking at my bug report. I have taken a video of the boot, and I am attaching it.
The video was taken immediately after entering the passphrase at the GRUB prompt. The prompt at the top left corner of the screen, says "Attempting to decrypt master key. Please enter passphrase for hd0,gpt1". Remember, I have /boot encrypted and I'm using GRUB's cryptomount as documented in the wiki at https://help.ubuntu.com/community/Full_Disk_Encryption_Howto_2019 I'm certain the password prompt is from GRUB, as if I enter the wrong password, I get dropped into a GRUB shell. At the eight second mark, you can see the GRUB menu pop up. When I hit enter to select "Ubuntu", the menu disappears and the Dell logo comes back on the screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1878107 Title: flicker-free boot gets interrupted by GRUB menu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1878107/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
