I rebooted with 3.18-rc5.  The graphics driver is now broken.  The 
system has reverted to a lower resolution.  Even when I try booting the 
previously working 3.16-24 and 3.16-23 I cannot get proper resolution.  
On 3.18-rc5 I cannot resume from suspend whether the suspend was 
performed manually or by closing and opening the lid. Remember in 14.10 
the system actually resumes.  The ONLY problem is that it does not turn 
the backlight on.  All I want is for someone to tell me what I have to 
do to turn the backlight on.  Otherwise 14.10 is resuming from suspend fine.

Meanwhile: How do I fix the graphics that were broken when I installed 
3.18-rc5?

Title:
  resume hang ubuntu 14.10 kernel 3.16

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Since upgrading to 14.10 every time I open the laptop lid the system
  hangs after enabling the keyboard but before turning on the display.
  That is the backlight on the LED screen is not turned on.  This issue
  has occurred occasionally since 12.4, but is now completely
  consistent.
