Black screen after wakeup

I know there is a lot of other posts like this, but I have been looking for hours and I still haven't found any solution.

I have recently installed Kubuntu Linux along side my Windows 7, the sleep on my Win7 works fine and resumes like normal. When I am loaded into Kubuntu, and I put my laptop to sleep, it goes into sleep as normal. When I go to RESUME from the sleep, the screen stays solid black, it doesn't light up, no blinking curser or anything. The Wi-Fi light is 'off' (orange) and I cannot turn it on. The Caps lock and the Num lock lights on the keyboard blink slowly. I hear something on the inside of the computer start to spin.

I am not very experienced with Kubuntu/Linux, but I do know a bunch of computer terminology, I am still far from an expert though.

I have about 300GB designated to my Win7 stuff, and another partition with about 100GB for my Kubuntu Linux.

My computers specs are as follows: Windows 7 64-bit I have the most recent version of Kubuntu because I just downloaded it a few days ago and updated it yesterday. AMD Athlon Duel-Core processor 4GB of RAM And it is a HP G61 Laptop

How big is your swap? For the sleep function to work, the swap has to be at least the size of your RAM. –  Lekensteyn Jun 19 '11 at 21:19
    
What is the model of your laptop, not the series? Does it do this after you lock/switch users? –  nickguletskii Jun 20 '11 at 9:42
    
did this ever get resolved –  jjesse Jan 1 '12 at 20:12

Suspend/sleep doesn't require swap, only hibernate does. Suspend on Ubuntu worked fine, but as I switched to Kubuntu, it doesn't work anymore. Likely a kernel + graphics driver bug.

What's your graphics card? Radeon HD?
