I fear the problem here might be in reality more than one and we should
get them into separate reports to make it simpler to work on them. The
symptom and maybe the overall problem might be the same but each
graphics type will need to be addressed individually. This report was
initially about vmwgfx. @Thomas, just for the records, do you still have
any issues?

Sergio, beside opening a new bug to have your specific hardware setup
recorded there, have you ever tried to enable the commented out line in
/etc/default/grub that enables text mode for the grub menu. Probably for
debugging one also wants to comment out the two lines about hidden
timeout. This brings up the grub menu on reboot without playing tricks
with pressing left shift at the right time (which I never manage). Make
sure to run "sudo update-grub" after changing that file.

>From slipch it would be important to know whether the nouveau or the
nvidia binary gfx driver is in use. But that should be automatically
included when filing bugs by running "ubuntu-bug linux". Since there is
no GUI up in the problem case this would have to be done after booting
with whatever workaround you have. Best after a "bad" boot since then
/var/log/syslog should have the info of the previous boot, too.I would
also suggest to include the driver in the title line (eg. ... boots to
blank console with nouveau).

After creating new bug reports, please add a comment here to report the
bug number(s). Thanks.

Title:
  Ubuntu 14.04 boots to blank console

Status in “linux” package in Ubuntu:
  Confirmed
Status in “linux” package in Debian:
  New
Status in “linux” package in Fedora:

Bug description:
  Ubuntu 14.04 as of 22:00 o'Clock Jan, 19th 2014 boots into blank console.
  Ctrl-Alt-F{1..6} does nothing or all consoles are blank, but "ps axf" shows /sbin/getty running on tty{1..6}:

  # ps axf | grep tty
    880 tty4     Ss+    0:00 /sbin/getty -8 38400 tty4
    885 tty5     Ss+    0:00 /sbin/getty -8 38400 tty5
    890 tty2     Ss+    0:00 /sbin/getty -8 38400 tty2
    891 tty3     Ss+    0:00 /sbin/getty -8 38400 tty3
    893 tty6     Ss+    0:00 /sbin/getty -8 38400 tty6
   4290 pts/1    S+     0:00                      \_ grep --color=auto tty
   1093 tty1     Ss+    0:00 /sbin/getty -8 38400 tty1

  
  Removing deprecated "vga=768" from kernel commandline => doesn't boot into 800x600, keeps 640x480
  Settings
    GRUB_GFXMODE=800x600
    GRUB_GFXPAYLOAD=800x600
  are ignored.

  Grub boots up with 800x600, switches back to 640x480 (setting
  GRUB_GFXPAYLOAD to "keep" it is the same) kernel doesn't switch back
  to 800x600.

  Adding deprecated "vga=768" back in:
  Grub boots up with 800x600, switches back to 640x480, kernel switches back to 800x600, but doesn't use this console. No output at all. Keys are accepted (you can login, but you'll have to guess what is going on on the screen).

  Exactly the same error is found with debian. Switching to a self
  compiled kernel solves this error. Looks a lot like some necessary
  stuff for console resolution switching is missing in the debian
  -/ubuntu-kernels.
