[Bug 1247907] Re: Ubuntu booting into black console

[Thomas Schweikle]

This was one of the things I tried. Without success. Same as before.
Btw.: the kernel prints a message vga= being deprecated and ignored thus
I suppose it not doing any harm any more.

I've tested now additionally:

Debian testing and unstable. Both have the very same problem. Only one difference:
Grub switches to 800x600, then, after loading the kernel but before transferring control, it switches back to 640x480. Unlike Ubuntu 12.10, 13.04, 13.10, it prints what the kernel logs up to the line: "Host SMBus controller not enabled!". Sometimes an additional line: "... Driver 'pcspkr' already registered, aborting..." is printed. Ubuntu 14.04 does this too, since applying the latest updates.

Debian stable and Ubuntu 12.04.3 do both work as expected: Grub
switching to 800x600, then back to 640x480 and then the kernel again
switches to 800x600 (if LINUX_GFXPAYLOAD is not set to 'keep').

Title:
  Ubuntu booting into black console

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  Setting

  GRUB_CMDLINE_LINUX_DEFAULT="vga=0x340"
  GRUB_CMDLINE_LINUX=""

  and

  GRUB_GFXMODE=800x600
  GRUB_GFXPAYLOAD=800x600

  then executing "update-grub" or "update-grub2" leads to booting Ubuntu without console. The screen is black and stays this way. The system itself is running! It is possible to remotely log in using ssh.
  Grub switches to 800x600, after the kernel overtakes, it switches back to 640x480, but never to 800x600 again. I've tried various combinations even "keep", but without success.

  Switching to

  GRUB_CMDLINE_LINUX_DEFAULT=""
  GRUB_CMDLINE_LINUX=""

  and

  GRUB_GFXMODE=
  GRUB_GFXPAYLOAD=

  makes the console been shown again, but not at higher resolution.

  I could find this problem with:

  Ubuntu 12.10 (Quantal Quetzal)
  Ubuntu 13.04 (Raring Ringtail)
  Ubuntu 13.10 (Saucy Salamander)
  Ubuntu 14.04 (Trusty Tahr)
