Title:
  Resume from suspend fails

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm running ubuntu on a Dell studio laptop with Intel® 965GM x86/MMX/SSE2 graphics. Most things work great, but every time I try to resume from  suspend the machine hangs. The screen simply stays black. I have to hold the power button to hard reset. The reboot then works ok. 
  I seem to remember that the resume used to work under 12.04 but since I upgraded to more recent versions it stopped working. I most recently upgraded to 14.10 hoping the problem would go away with more recent versions, but no luck. I've searched around a lot, found a post that suggested that looking at file /var/log/Xorg.0.log.old might give useful information.
  That file does indeed state a few things that seem relevant to me, such as:

  ...
  [    33.637] (II) Loading /usr/lib/xorg/modules/libfbdevhw.so
  [    33.638] (II) Module fbdevhw: vendor="X.Org Foundation"
  [    33.638] 	compiled for 1.16.0, module version = 0.0.2

  [    35.971] (II) UnloadModule: "intel"
  [    35.971] (EE) Screen(s) found, but none have a usable configuration.
  [    35.971] (EE) 
  Fatal server error:
  [    35.971] (EE) no screens found(EE) 
  [    35.971] (EE) 
  Please consult the The X.Org Foundation support 
  	 at http://wiki.x.org
   for help. 
  [    35.971] (EE) Please also check the log file at "/var/log/Xorg.0.log" for additional information.
  [    35.971] (EE) 
  [    36.014] (EE) Server terminated with error (1). Closing log file.

  
  I guess if "drm failed" and as a result "no screen has a usable configuration" then that would explan why the screen simply stays black on resume, but I have no idea how to debug this further or how to fix it.
  Any help / advice much appreciated.
