With the lateset upstream kernel, 3.16.0, the bug still exists but the
behavior is different. Upon resume, the login screen appears and does
allow me to login, but then the screen goes blank after successfully
logging in. At that point I am able to CTRL-ALT-F1 to get a console and
kill my xvfe session to start a new one.

Title:
  Screen goes blank after resume from suspend

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  After upgrading to Xubuntu 14.04, whenever I close the lid to my
  laptop to suspend it and then reopen it, the computer appears to
  resume properly (power light, hard drive light, wireless light are all
  lit), but the screen turns on for a second then turns off. There is
  nothing I can do but hit the power button to power off the machine.
  Upon powering back up everything is normal.

  Attempts to go to the console by hitting CTRL-ALT-F1 do nothing. The
  screen stays off.
