Nothing is displayed and the screen remains turned off, including backlights (this is diferent from having backlights on again a blackscreen displayed on screen). I can reproduce the same behaviour by using the pm-suspend command from shell, or clicking "suspend to ram" into the exit menu. If I boot from the 3.19.0-15 kernel, everything works properly. I tried another kernel picked up from here http://kernel.ubuntu.com /~kernel-ppa/mainline/?C=N;O=D following this wiki page https://wiki.ubuntu.com/Kernel/MainlineBuilds?action=show&redirect=KernelMainlineBuilds (respectfully the v4.1-rc3-unstable and v4.1-rc2-vivid and I got the same problem each time.
