[Bug 2012181] Re: lunar (alpha) grub "no usable video mode found"

[David Coe]

Many thanks Julian! I had downloaded the 2ubuntu17 debs from your
'proposed' site and was in the process of trying them.

I now have

  grub-efi_2.06-2ubuntu17_amd64.deb
  grub-efi-amd64_2.06-2ubuntu17_amd64.deb
  grub-efi-amd64-bin_2.06-2ubuntu17_amd64.deb
  grub-efi-amd64-signed_1.193+2.06-2ubuntu17_amd64.deb
  grub-pc-bin_2.06-2ubuntu17_amd64.deb

installed on the Vostro after having to use apt --fix-broken to clear
out the back-graded 2ubuntu12.1 package setup :-(.

The error diagnostics (no server specified, ... ) have gone!! However,
the grub menu does not auto-detect 1920x1080 resolution, respond to
GRUB_GFXMODE changes nor (I think) to the alternative breeze grub theme
layout. These were all OK with 2ubuntu12.1 but may either be a separate
problem or I may have bungled which grub deb packages need to be
installed.

Is there any thing further I might try? The other amd64 machines in the
MPI cluster seem stable so I'm inclined to let sleeping dogs lie :-).

Best regards

Title:
  lunar (alpha) grub "no usable video mode found"

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  I'm bare-metal testing Kubuntu Lunar 23.04 on a collection of amd64
  machines connected in an MPI cluster. Things have gone very smoothly
  indeed, despite it being still an alpha-release!

  However, one machine (an elderly Dell Vostro 400) is showing a
  regression for Grub 2.06-2ubuntu16 compared with Kinetic 22.10. The
  following occurs during boot-up:

    error: no server specified
           no suitable video mode found
           no video mode activated

  The grub menu stubbornly displays at 640x480 (AMD Turks driving a LG
  24EA52 1920x1080 monitor usually picks up just fine). Auto-detection
  no longer functions and manual changes to GRUB_GFXMODE are ignored.

  X11 starts and KDE initializes as usual (and at the correct
  resolution), so the error message is somewhat cosmetic and doesn't
  seem to affect more modern machines. Nonetheless, it does seem a bug
  that could/should be corrected.

  Best regards and thank you.
