This is a recurring problem that I've had with Ubuntu literally since I first started using linux about a year ago. It seems that whenever I have my laptop suspend for about more than 30 minutes, the system freezes upon waking up. I can see the login screen, however I cannot type anything in, nor move my mouse. The only solution is to hold the power button until it turns off. I've researched this problem for a few weeks now, without finding any real solutions. Does anyone have any idea on what I could do to prevent my system from freezing upon wake up?

I'm using a Lenovo Ideapad u430 Touch, with an Intel i5 4210 CPU and Intel® HD Graphics 4000.
