[Bug 1247907] Re: Ubuntu booting into black console

[Sohoffice]

I'm having the same issue with a freshly installed 13.10 server x64.
The kernel is 3.11.0-12-generic, and the graphic card is AMD HD 7770.
Setting GRUB_CMDLINE_LINUX_DEFAULT="nomodeset" shows me the login prompt, but the resolution is quite low.

Before I reached there, I've tried to experiment with GRUB_GFXMODE and GRUB_GFXPAYLOAD, but these doesn't seem to be relevant.
In the end, I've reverted all the changes and switch to add the nomodeset parameter which gave me the login prompt.

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)
