[Bug 1247907] [NEW] Ubuntu booting into black console

[Thomas Schweikle]

Public bug reported:

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)
