I have occasionally problem with ubuntu 14.10(or 14.04), when I wake up from sleeping, screen remains black. My notebook is Lenovo IdeaPad Z50-70 and graphics is NVIDIA GeForce GT 840M 4GB. Is there any solution for this? Thanks in advance.

This problem has been reported all over, dunno why it's not being addressed for over a year: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/1528735
