testing reveals that the bug is linked to lightdm
It is not reproducible when lightdm is not running. When lightdm is running, a wide range of kernels show the resume fail. These kernels do not fail resume when lightdm is not running

** Description changed:

  does not resume (no backlight on LCD panel, for example)
+ seems to be caused by lightdm not by kernel; when 
+ service lightdm stop
+  bug is not reproduced by pm-suspend
