I am more or less a complete Linux noob, and using 12.04 for the first time. Everything works great, and I am very happy, but there is one exception: suspend won't resume. Every time I suspend my computer, (whether by clicking suspend or by closing the lid) it goes to a black screen (with the backlight on) but there is no way to wake it up.

I've tried doing Fn+F8 to see if the screen was off, but it didn't work. I tried keyboard, mouse and power button, but nothing works, and I have to shut down and restart.
