I did a clean install of Ubuntu 14.04. When I resume from suspended the system freezes after I enter my password. I am forced to power off and start again. I had a similar problem on this laptop when I upgraded to 13.04 and don't recall how I fixed it.

I installed the proprietary Nvidia drivers as given in this post by "floppy". Voila! My system resumes from suspend without any hitch.
