[Bug 2012181] Re: [lunar+] grub: no server specified, no suitable video mode found

[David Coe]

I can confirm the bug is fixed for 23.10 RC on my Vostro 400. If you
need to run 23.04 on a non-UEFI machine, back-grading grub2-common grub-
common grub-pc grub-pc-bin to the 2ubuntu12.1 debs from the Kinetic
archive has worked without issue for me these last 6 months.

Many thanks, good people!

Title:
  [lunar+] grub: no server specified, no suitable video mode found

Status in grub2 package in Ubuntu:
  Fix Released

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.
