Public bug reported:
Whenever I try to suspend my laptop(Dell Latitude 3440, currently
running ubuntu 14.04 with 4.4.0-31-generic) the screen goes black and it
freezes and it does not suspend properly. I am only left with option of
forcefully shutting it down. I previously thought the bug was due to
using of nvidia drivers, so i deleted all the drivers. The problem was
still there so i thought of upgrading the kernel to the latest kernel
and deleting the old ones. So i deleted the old kernels after installing
4.4.0.
