For me killing unity-panel-service as a last resort doesn't work (anymore). 
I am sometimes, but not always, lucky by preforming these voodoo steps:
1) switch to a VT (text terminal, e.g. CTRL-ALT-F1), log in and type "startx". 
2) It starts another X session, and asks for a password ("authentication is required to change your own userdata"). Just press ESC a few times, and you end up with an empty, unusable desktop. You can't do much here. 
3) Now switch back to the VT  (again CTRL-ALT-F1) and press CTRL-C, which kills the new X session. 
4) press CTRL-ALT-F7 to switch back to the original (black-screen) X session, which hopefully snapped out of blackness by the above steps.

This bug is causing data loss much of the time, as it prevents accessing
all your open apps and documents after suspending/resuming.

Title:
  Black screen after resuming from suspend

Status in X.org xf86-video-intel:
  New
Status in xserver-xorg-video-intel package in Ubuntu:
  Incomplete

Bug description:
  Using Ubuntu 14.10 on a Lenovo Yoga 2, when I resume the laptop from
  suspend I frequently (around 50% of the time) get a blank black screen
  with a mouse cursor on it, and am unable to login or interact with the
  desktop at all. Often (also about 50% of the time) switching over to a
  text terminal and killing "unity-panel-service --lockscreen-mode"
  causes it to snap out of it and prompt me with the unlock dialog when
  I switch back to X.
